Completion Analysis:
a) Plato described Atlantis as an ideal state, and the name is considered synonymous with Utopia - This option provides additional information about Plato's depiction of Atlantis but does not address the question of its existence.
b) Plato's accounts of Atlantis are in his works Timaeus and Critias, and these philosophical dialogues are the earliest known references to Atlantis - This option highlights the source of information about Atlantis but does not address the conclusion about its existence.
c) The legend of Atlantis is frequently featured in many books, movies, television series, and other creative works - While this option mentions the popularity of the Atlantis legend, it does not address the scientific consensus on its existence.
d) While there are many hypotheses about Atlantis, the vast majority of scientists conclude that Atlantis never existed - This option directly addresses the question by stating that scientists generally believe Atlantis is a fictional island and not a historical reality.

Correct Answer:
The best completion for the sentence is option 'D' because it provides a clear and concise answer to the question of Atlantis's existence based on scientific consensus.

Mary: Are you kidding? We are in June.
Tom: So what? What's wrong with June?

  • c)
    I didn't know your brother knew so much about gardening.
  • d)
    Have you got any idea what the right time is to shorten rose plants?
Correct answer is option 'B'. Can you explain this answer?

Tanishq Mehra answered
Answer:

Understanding the dialogue:
In the given dialogue, Tom and Mary are discussing the right time to trim roses. Tom seems to be unaware of the appropriate timing, while Mary corrects him by stating that the beginning of winter is the right time to trim roses when they lose their flowers.

Explanation of the answer:
The most appropriate option to complete the dialogue is option 'B': "Can you help me prune the roses in the garden at the weekend?" This option is suitable because it directly addresses Mary's suggestion about trimming the roses. Additionally, it shows Tom's willingness to seek help and actively participate in the task.

Explanation of other options:
a) "Are you going to plant those roses in your garden in June or July?": This option is not relevant to the dialogue as it talks about planting roses, whereas the conversation is about trimming them.
c) "I didn't know your brother knew so much about gardening": This option is a random statement that does not contribute to the dialogue or address the topic of discussion.
d) "Have you got any idea what the right time is to shorten rose plants?": This option is close to the correct answer but lacks the request for help or participation, which option 'B' provides.

Therefore, option 'B' is the most appropriate completion for the dialogue as it directly addresses the topic of discussion and shows Tom's willingness to participate in trimming the roses.

Sandra's Vision Problem

Sandra: ________

George: Then you should start wearing glasses.

Sandra: I already have contact lenses, but still I can't see clearly.

George: It's time you changed them, then.

Options:
a) When did you last go to an eye doctor?
b) Should I tell my grandmother to see an optician?
c) I can't see the sentences on the board.
d) Are you able to see better now?

The most appropriate option to complete Sandra's dialogue is option 'c' - "I can't see the sentences on the board."

Explanation:

In the dialogue, Sandra mentions that she already has contact lenses but still faces difficulty in seeing clearly. This implies that her current vision correction method is not working effectively.

When George suggests that she should start wearing glasses, Sandra responds by saying that she can't see the sentences on the board. This indicates that her vision problem is specifically related to her ability to see written sentences on the board.

Key Points:
- Sandra already has contact lenses but can't see clearly.
- Her vision problem is not resolved by the contact lenses.
- Sandra mentions her difficulty in seeing sentences on the board.
- This indicates that her vision problem is related to her ability to see written text.

Therefore, option 'c' - "I can't see the sentences on the board" is the most appropriate option to complete Sandra's dialogue.

Father: What? You crashed the car again?
Son:________
Father: I'm sure it wasn't. This is the third accident you have had this year.
Son: You're very angry now, dad. We better talk about this later.

The most appropriate option to complete the dialogue is:

c) But it wasn't my fault. You've got to believe me.

Explanation:

The son's response of "But it wasn't my fault. You've got to believe me" is the most appropriate option to complete the dialogue. This response shows that the son is denying responsibility for the car accident and wants his father to believe him.

Here's a breakdown of the dialogue:

Father: What? You crashed the car again?
- The father is expressing surprise and disapproval at the fact that his son has crashed the car once again.

Son: But it wasn't my fault. You've got to believe me.
- The son is defending himself by stating that the accident was not his fault and requesting his father to believe him. This response implies that the son feels unjustly blamed for the accident and wants his father to trust his word.

Father: I'm sure it wasn't. This is the third accident you have had this year.
- The father expresses doubt about the son's claim and emphasizes the fact that this is not the first car accident the son has been involved in this year. The father's response suggests frustration and disappointment in his son's repeated accidents.

Son: You're very angry now, dad. We better talk about this later.
- The son acknowledges his father's anger and suggests discussing the issue at a later time when both parties are calm. This response shows that the son recognizes the need for open communication and resolution of the issue.

In this dialogue, option c) is the most appropriate because it captures the son's attempt to defend himself and seek understanding from his father. It also sets the stage for further discussion to resolve the conflict between them.

The simple past tense is indicated by "read" in Option D, where "yesterday" confirms it is a past action. Option B could be either past or present depending on pronunciation but lacks a clear time reference, making D the correct choice.

  • c)
    Is it possible for you to wait for the end of the meeting?
  • d)
    You had better go home and take a rest.
Correct answer is option 'D'. Can you explain this answer?

Tanishq Mehra answered
Explanation:
- The dialogue starts with Rosy expressing concern for Amit's well-being.
- Amit responds by saying that he can wait until the end of the meeting.
- Rosy disagrees with Amit's statement, saying that he can't keep his eyes open.
- Amit then acknowledges Rosy's concern and agrees to go home and rest.

Analysis of Options:
a) "Are you feeling better today than yesterday?" - This option does not fit the context of the dialogue. There is no mention of Amit feeling sick or unwell.
b) "Can you tell me why you're smiling all the time?" - This option does not fit the context of the dialogue. There is no mention of Amit smiling or any indication that his behavior needs explanation.
c) "Is it possible for you to wait for the end of the meeting?" - This option is similar to Amit's initial response, which Rosy disagrees with. It does not address Rosy's concern about Amit's tiredness.
d) "You had better go home and take a rest." - This option is the most appropriate completion of the dialogue. It acknowledges Rosy's concern and agrees to her suggestion that Amit needs rest.

Conclusion:
The most appropriate option to complete the dialogue is d) "You had better go home and take a rest." This option addresses Rosy's concern and acknowledges the need for Amit to rest.

A fax machine works by scanning each outgoing page, turning the image into a series of light and dark dots. This pattern is then translated into audio tones, and sent over regular phone lines. The receiving fax "hears" the tones, pieces the grid together, and prints the total number of dots _______.
  • a)
    He invented a machine capable of receiving signals from a telegraph wire
  • b)
    They were an easy way to send documents to any phone number
  • c)
    The resulting document is a black and white copy of the original page
  • d)
    Then he finally managed to translate these symbols into images on paper
Correct answer is option 'C'. Can you explain this answer?

Surbhi Patel answered
Explanation:

Scanning and Transmission Process:
The fax machine scans the outgoing page and converts the image into light and dark dots. These dots are then translated into audio tones and sent over regular phone lines.

Receiving Process:
The receiving fax machine decodes the audio tones it receives, reconstructs the grid of dots, and prints the total number of dots on the receiving end.

Resulting Document:
As a result of this process, the document that is printed at the receiving end is a black and white copy of the original page that was scanned and transmitted.
Therefore, the correct completion of the sentence would be option c) "The resulting document is a black and white copy of the original page." This option accurately describes the outcome of the fax transmission process where the total number of dots is printed as a black and white copy of the original document.

The jaguar is sometimes called Americans El Tigre by South and Central Americans _______. Both names convey the awe and reverence this largest New World cat inspires. Their gold coat spangled with black rosettes was said to be the stars of night. In the Mayan religion, the sun took the form of a jaguar when travelling through the underworld at night.
  • a)
    Jaguars live in the rain forests and more open countryside in South and Central America
  • b)
    They are known to be the largest members of the cat family there
  • c)
    Long ago, they called it Yaguara, the "cat that kills with a single spring"
  • d)
    None of these
Correct answer is option 'D'. Can you explain this answer?

Akshita Reddy answered
The Context of the Sentence
The sentence discusses the jaguar, its significance, and the cultural references associated with it. The phrase "Americans El Tigre" suggests a connection to the cultural reverence for the jaguar in South and Central America.
Analysis of Options
- Option A: "Jaguars live in the rain forests and more open countryside in South and Central America."
This option describes the habitat of jaguars but does not complete the idea about the names given to the jaguar, making it less relevant.
- Option B: "They are known to be the largest members of the cat family there."
While this option provides factual information about jaguars, it fails to connect to the cultural significance implied by the names "El Tigre."
- Option C: "Long ago, they called it Yaguara, the 'cat that kills with a single spring.'"
This option provides historical context and cultural significance, but it does not directly relate to the name "Americans El Tigre" and the awe associated with the jaguar.
- Option D: "None of these."
This option is correct because none of the previous options effectively complete the sentence in a meaningful way that relates to the cultural reverence and awe conveyed by the names.
Conclusion
The correct answer is option 'D' because the other options fail to provide a relevant completion that ties back to the cultural significance of the jaguar as highlighted in the initial part of the sentence.

Correct answer is option 'D'. Can you explain this answer?

Tanishq Mehra answered
Explanation:
In the dialogue, Chris suggests leaving the car and walking to the bank. However, Nick disagrees with this idea because he thinks it is difficult to find a parking place near the bank.

Reasoning:
- Chris suggests leaving the car and walking, indicating that he prefers to walk to the bank.
- Nick disagrees with this idea, stating that it is difficult to find a parking place near the bank.

Analysis of options:
a) "It may take more than hours to walk to the bank" - This option does not provide a reason for Nick's disagreement. It also does not address the issue of finding a parking place near the bank. Therefore, it is not the most appropriate option to complete the dialogue.
b) "They've decided to open a new branch near here?" - This option is unrelated to the dialogue. It does not provide a reason for Nick's disagreement or address the issue of finding a parking place near the bank. Therefore, it is not the most appropriate option to complete the dialogue.
c) "Normally, I walked to school from home" - This option is unrelated to the dialogue. It does not provide a reason for Nick's disagreement or address the issue of finding a parking place near the bank. Therefore, it is not the most appropriate option to complete the dialogue.
d) "But it's very difficult to find a parking place near the bank" - This option directly addresses Nick's disagreement and provides a reason for not leaving the car and walking to the bank. It is the most appropriate option to complete the dialogue.

Conclusion:
Based on the analysis of the options, option 'D' - "But it's very difficult to find a parking place near the bank" is the most appropriate option to complete the dialogue.

Correct answer is option 'D'. Can you explain this answer?

Muskaan Joshi answered
Error Identification:

The error in the sentence is in the usage of the pronoun 'whom'.

Corrected Sentence:

I found this ring as I dug the garden. It looks very old. I wonder who it belonged to.

Explanation:

The pronoun 'whom' is used to refer to the object of a verb or a preposition. In the given sentence, 'whom' is used to refer to the owner of the ring. However, 'whom' is not the correct pronoun to use in this context. 'Whom' is used when the object is the receiver of the action. In this sentence, the ring did not belong to anyone at the time of finding it. Therefore, the correct pronoun to use in this context is 'who' which is used to refer to the subject of a verb.

  • d)
    correct, as is
Correct answer is option 'A'. Can you explain this answer?

Sanskriti Bose answered
Understanding the Correction
The passage requires grammatical corrections to convey the message clearly. Let's analyze the options and their correctness.
Original Mistakes
1. "You dont see to brush your teeth regularly."
- Correction: "You don't seem to brush your teeth regularly."
2. "Actually, me do, but I eat a lot of sweets."
- Correction: "Actually, I do, but I eat a lot of sweets."
3. "She know how bad them are for health, don’t you."
- Correction: "She knows how bad they are for health, don’t you?"
Explanation of Option A
- "seem" instead of "see":
This is the correct verb to indicate appearance or an impression.
- "I" instead of "me":
"I" is the correct subject pronoun that should be used.
- "you" instead of "he":
The dentist is addressing the patient directly, so "you" is appropriate.
- "they" instead of "them":
"They" is used as the subject of the clause, while "them" is an object pronoun.
Why Other Options Are Incorrect
- Option B: "sit, I, he, their"
- "sit" is incorrect; the right verb is "seem." "he" is not appropriate in this context, and "their" does not match the subject.
- Option C: "seem, you, I, their"
- "I" is incorrectly used as the subject, and "their" does not fit the context.
- Option D: "correct, as is"
- The passage contains several grammatical errors that need correction.
Conclusion
Thus, option A is the most suitable choice, as it corrects the passage effectively while maintaining the intended meaning.

Monarch butterflies travel long distances to stay warm. They fly up to 3,000 miles to the same winter roosts, sometimes to the exact same trees. However, their life span is only a few months _______. Their great-great-grandchildren return south the following fall.
  • a)
    baby swallows and their parents learn each other's voices
  • b)
    most of the bird species migrate south for the winter
  • c)
    other butterflies also fly thousands of miles in search of warmth
  • d)
    so individual monarchs only make the round-trip once
Correct answer is option 'D'. Can you explain this answer?

Rounak Chawla answered
Understanding the Monarch Butterfly's Journey
The completion of the sentence in the context provided is crucial to understanding the life cycle and migration patterns of monarch butterflies.
Key Points of the Answer
- Life Span Context: The sentence states that monarch butterflies have a life span of only a few months. This sets the stage for understanding their migration behavior.
- Migration Explanation: The phrase "so individual monarchs only make the round-trip once" (option D) logically follows from the information given. It emphasizes the fact that due to their short life span, a single monarch will not live long enough to complete the entire journey to their winter roosts and back again.
- Contrast with Other Options:
- Option A: "baby swallows and their parents learn each other's voices" is irrelevant to monarchs and does not relate to their migration.
- Option B: "most of the bird species migrate south for the winter" discusses birds, not butterflies, and does not connect to the life span of monarchs.
- Option C: "other butterflies also fly thousands of miles in search of warmth" is true but does not relate directly to the individual life span of monarchs.
Conclusion
In summary, option D effectively ties together the monarch butterfly's limited life span with its migration behavior, making it the best choice to complete the sentence. This illustrates the unique and fascinating life cycle of these remarkable insects.

Nina: Why are you always complaining about your parents?
Nina is asking Mark why he constantly complains about his parents. This question implies that Mark frequently expresses dissatisfaction or annoyance with his parents.

Mark: That's because they never stop criticizing me.
Mark responds to Nina's question by stating that his parents constantly criticize him. This implies that their critical behavior is the reason why he complains about them.

Nina: Why don't you try telling them how you feel about it?
Nina suggests that Mark should communicate his feelings to his parents. She encourages him to express himself and let them know how their criticism affects him.

Mark: Do you think I haven't? They just don't care about how I feel.
Mark responds to Nina's suggestion by saying that he has indeed tried telling his parents how he feels, but they are indifferent to his emotions. This implies that despite his attempts to communicate, his parents do not show any concern or understanding towards his feelings.

Therefore, the most appropriate option to complete the dialogue is:
a) Why are you always complaining about your parents?
This option aligns with the context of the conversation between Nina and Mark. Nina's initial question and Mark's response indicate that Mark frequently complains about his parents due to their constant criticism.

In each iteration, the entering variable is selected based on the optimality condition, which involves calculating the ratios of the right-hand side (RHS) coefficients bi to the coefficients of the entering variable a.

If all ratios are negative, it means that the objective function is unbounded in the direction of the entering variable. In other words, we can increase the value of the entering variable indefinitely while still satisfying all constraints, which leads to an unbounded solution. This situation occurs when the feasible region is not bounded, and the objective function can increase or decrease without limit.

Therefore, the correct answer is option D, unbounded solution.

Summary:

- Simplex method requires selecting an entering variable based on the optimality condition.
- If all ratios of RHS coefficients to entering variable coefficients are negative, the problem has an unbounded solution.
- An unbounded solution occurs when the feasible region is not bounded and the objective function can increase or decrease without limit.

What has Pravah decided to become?
  • a)
    I strongly advise he becomes a lawyer.
  • b)
    He offered to become a lawyer.
  • c)
    I think he's considering becoming a lawyer.
  • d)
    He had not decided yet.
Correct answer is option 'C'. Can you explain this answer?

Praveen Kumar answered
Pravah is considering becoming a lawyer, which indicates he is still in the process of making a decision. The word "considering" suggests that the decision is not final but is being carefully thought out. The other options imply either advice or a lack of decision, but C captures the process of deliberation.

You can study grammar rules from a book,
  • a)
    they will improve your speaking ability.
  • b)
    they will improve your driving ability.
  • c)
    but you can only learn to speak English by speaking.
  • d)
    they will improve either your speaking or writing ability.
Correct answer is option 'C'. Can you explain this answer?

Praveen Kumar answered
While grammar rules are important, speaking is a skill that improves with practice, not just study. Option C emphasizes that true language fluency comes from actual communication, which is a key distinction between theoretical learning and practical application.

Which sentence is written in the present perfect tense?
  • a)
    I have eaten lunch.
  • b)
    I eat lunch.
  • c)
    I will eat lunch.
  • d)
    I ate lunch.
Correct answer is option 'A'. Can you explain this answer?

Shiksha Academy answered
The present perfect tense is formed by "have" followed by the past participle of the verb, "eaten." This tense shows an action that was completed at some point before now, without specifying when.

Your secretary thanks you for giving her a lift. What will you say?
  • a)
    I enjoyed your company after all.
  • b)
    Oh! Don't mention it. I was coming past your house anyway.
  • c)
    I wanted to know where you live.
  • d)
    You are always welcome.
Correct answer is option 'B'. Can you explain this answer?

Vp Classes answered
Option B is a polite and natural response to someone thanking you for a favor. It downplays the action as a small gesture, making the recipient feel more comfortable. The other responses either sound formal or a bit awkward in this context.

two-week holiday. We had been chosen our destination carefully.

    had
  • b)
    been

  • d)
    ok
Correct answer is option 'B'. Can you explain this answer?

Jay Goyal answered
Analysis of the Sentence
The sentence provided is: "We had been chosen our destination carefully." Upon review, it is clear that there is a grammatical error.
Identifying the Error
- The phrase "had been chosen" is incorrect in this context.
- The correct phrase should be "had chosen," indicating that the subject (we) made a choice regarding the destination.
Correct Option
- Thus, the correct choice is option b) been, as it is the extra word that makes the sentence grammatically incorrect.
Revised Sentence
- The revised sentence should read: "We had chosen our destination carefully."
Explanation of the Correction
- "Chosen" is the past participle of "choose," and in this case, it should be used with "had" to indicate that the action of choosing was completed before another action (like going on a holiday).
- The inclusion of "been" creates a passive construction that does not fit the intended meaning, making the sentence confusing.
Conclusion
- The error lies in the unnecessary inclusion of "been," and correcting it clarifies the intended message about actively selecting the holiday destination.
This detailed analysis clarifies why option 'B' (been) is the correct answer in this context.

He was going to stroke the dog, but
  • a)
    it bit him on the leg
  • b)
    it cut him on the arm
  • c)
    it hit him on the head
  • d)
    it ate him on the shin
Correct answer is option 'A'. Can you explain this answer?

Vp Classes answered
Dogs are more likely to bite someone if they feel threatened or uncomfortable, making Option A the most plausible. The other actions (cutting, hitting, or eating) are not logical in the context of a dog's behavior.

The variance of the completion time for a project is the sum of variances of
  • a)
    all activity times
  • b)
    non-critical activity times
  • c)
    critical activity times
  • d)
    activity times of first and last activities of the project
Correct answer is option 'C'. Can you explain this answer?

Gauri Sarkar answered
Explanation:


The variance of the completion time for a project is the sum of variances of critical activity times. This is because critical activities have no slack time, and any delay in critical activities will delay the overall completion time of the project. Thus, the critical activity times have the greatest impact on the completion time variance.

Reasoning:


The variance of completion time for a project is a measure of the spread of completion times around the expected completion time. It is affected by the variance of the activity times and the dependencies between the activities. The critical path of a project is the longest path of dependent activities, and any delay in a critical activity will delay the overall completion time of the project. Therefore, the critical activity times have the greatest impact on the variance of the completion time of the project.

Conclusion:


In conclusion, the variance of the completion time for a project is the sum of variances of critical activity times. This is because critical activities have no slack time, and any delay in critical activities will delay the overall completion time of the project. Therefore, it is important to identify and focus on critical activities to minimize the variance of the completion time of the project.
