• Python.
• Visual Basic.
• C.
• C++.

Key Points

• The segment of the sentence that contains a grammatical error is "was one of those thing you never".
• In the phrase "one of those things", the word "things" should be plural because "one of" is referring to any one member of a group or category.
• The group or category (in this case, "things") is always plural in this construction.

Therefore, the correct sentence should be: "We talked about writing a will, but it was one of those things you never get around to doing."

Formula used:

Calculation:

Let the smallest number be X

According to the question

⇒ X + (X + 2) + (X + 4) + (X + 6) + (X + 8) = (25 × 5)

⇒ 5X + 20 = 125

⇒ 5X = 125 - 20

⇒ 5X = 105

⇒ X =

∴ The smallest number is 21.

• When a large force acts on a body for a short time, then the force is called impulsive force.
• Impulse = force x time = change in momentum
• Impulse is a vector quantity.
• SI Unit of Impulse is Newton second (Ns).

Explanation

Impulse

• When a large force works on a body for a very small time interval, it is called impulsive force.
• An impulsive force does not remain constant, but changes first from zero to maximum and then from maximum to zero. In such a case, we measure the total effect of force.
• The impulse caused by a force during a specific time interval is equal to the body's change of momentum during that time interval.
• Impulse, effectively, is a measure of change in momentum.
• The impulse of a force is a measure of the total effect of force.
• Impulse is a vector quantity and its direction is the same as that of force.
• SI unit of impulse is Newton-second or kg-m-s^-1 and CGS unit is g.m/s

Key Points

• Containers for keeping the strong acids are made up of Lead.
• Lead containers are used for storing or carrying radioactive materials.

Additional Information

• Lead is an element of the periodic table with an atomic number of 82.
• The symbol of the element is Pb.
• Uses of Lead:
  • It is a metal that has been used since Roman times for making paints and pipes corrosion-resistant.
  • It is used in batteries. For eg. lead-acid batteries.
  • For soldering and electrolysis process.

By using the following symbols in the table given below, we can draw the following family tree:

According to the given information:

• Z is the brother of Y, who is the son of W. W is married to S.

• S's brother X is the only son of C.

​X is the only son of C so, S is the daughter of C.

• Q is the paternal grandmother of Y and married to P.

• B is the father - in - law of W.

Clearly, P is 'Father - in - law' of S.
Hence, the correct answer is "Father - in - law".

Concept used:
Sin (90° - θ) = Cosθ
Calculation:
Sin² 35° + Sin² 55°
⇒ Sin² (90° - 55) + Sin² 55°
⇒ Cos² 55° + Sin² 55° = 1
∴ The correct option is 2

Key Points

• As we can see the given sentence is in the active voice format of the simple past tense as the past participle (celebrated) is applied in the sentence, so we have to change the active voice as per the same tense rules.
  • Active voice: Subject + V2 + object
  • Passive voice: Object + was/were + V3 + by + subject
  • Example:
    • Active voice: Maya cleaned the dishes.
    • Passive voice: The dishes were cleaned by Maya.
• By following the above-mentioned rules, we have to change the active to passive by applying the third form of the verb (celebrated) and past helping verb (was) in the sentence.

Therefore, the correct answer is: The Independence Day was celebrated by the residents.
Additional Information

• Let us take a look at the rules of simple past active passive voice:
• Active voice: Subject + V2 + object
• Passive voice: Object + was/were + V3 + by + subject
• Active voice: Subject + did + not + v1 + object
• Passive voice: Object + was/were + not + V3 + by Subject
• Active voice: Did + subject + V1 + object +?
• Passive voice: Was/were + Object + V3 + by subject +?

Triple-click (Ctrl + click) on a sentence to select it is used to select a sentence in a paragraph in MS Word.

Mistake Points

• Double click can only select a single word but Ctrl + Click on a statement can select complete statement. Hence option 3 is correct and 4 is incorrect.

Key Points
Shortcut in MS word for selection:

• To select the current word, double-click on it.
• To select the current paragraph, triple-click on the paragraph.
• To select a sentence and not just a line, hold down [Ctrl] and click once in any place within the sentence.
• To select a vertical block of text, click at the start of the block. Later, hold down the [Shift] key and click a second time at the opposite end of the block. This trick is used when only want to copy one column of a tabular list

Approach (to find the difference in the shortcut)
These can be easily understood if you do it practically on MS word as it has very minute differences which you need to see while performing and reading each point.

While changing the narration of an exclamatory sentence, we need to follow these steps-

• If the sentence is giving making an exclamation with sorrow (Alas! is an expression of sorrow), we make the following changes-
  • The reporting verb said is changed into exclaimed. We add the feeling indicated by the exclamation i.e. sorrow along with the preposition 'with'.
  • The conjunction 'that' is used in place of commas and inverted commas.
  • The tense changes from the simple past tense to past perfect tense.

Eventually, we will get the final sentence- She exclaimed with sorrow that she had failed the test.

  • Identify the subject, verb, and object in the active voice sentence.
  • The subject of the active sentence becomes the object of the passive sentence.
  • The verb is changed to the past participle form.
  • A form of the verb "to be" is added to the past participle form of the verb.
  • The agent (the person or thing performing the action) is added to the sentence in a prepositional phrase beginning with "by."
  • The adverbial phrase is moved to the end of the sentence.
• The general structure is:
  • Active voice: Subject + Verb + Object
  • Passive voice: Object + Auxiliary Verb (be) + Past Participle + (by Subject)
• The subject is "He", the verbs are "picked up" and "flung", and the object is "a bar of soap".
• The object "a bar of soap" now becomes the subject of the sentence, and the original subject "He" is introduced by "by" after the verb.
• The verb "picked up" and "flung" are in the past simple tense in active voice, so in passive voice they become "was picked up" and "flung".
• Therefore, the correct Passive voice is: "A bar of soap was picked up by him from the basin, and flung across the room."

Hence option 3 is correct.
