- This option correctly uses a comma to connect the clauses, creating a concise and logical sentence structure. The word "eliminating" accurately describes the action of water filters.
d) through, so they eliminate
- This option uses the phrase "so they eliminate" after a comma, which is not grammatically correct. Additionally, the word "so" implies a cause-and-effect relationship, which is not explicitly stated in the sentence.

| | Rajeev Kumar answered |
This option is the most appropriate and grammatically correct. It uses a relative clause "whose ordering systems maximize efficiency both in the kitchen and behind the counter" to provide additional information about the restaurants. The sentence structure is clear and concise, making it easy to understand. It also correctly uses the verb tense to indicate that the expansion of seating spaces happened in the past.
Language opens the door to other perspectives. What’s given to us is the means to apprehend other ways of viewing our common world and our common humanity.- a)Language opens the door to other perspectives while giving to us the means
- b)Language opens the door to other perspectives by giving us the means
- c)By opening the door to other perspectives through language, we are given the means
- d)Although language opens the door to other perspectives, we are given the means
Correct answer is option 'B'. Can you explain this answer?
Language opens the door to other perspectives. What’s given to us is the means to apprehend other ways of viewing our common world and our common humanity.
a)
Language opens the door to other perspectives while giving to us the means
b)
Language opens the door to other perspectives by giving us the means
c)
By opening the door to other perspectives through language, we are given the means
d)
Although language opens the door to other perspectives, we are given the means
| | Rajeev Kumar answered |
The sentence presents a cause-and-effect relationship between language and our ability to understand different perspectives. To express this relationship correctly, we need to use a coordinating conjunction (such as "by") and a pronoun (such as "us") to convey the cause and the effect, respectively.
Option A uses the coordinating conjunction "while," which implies a contrast between two ideas, rather than a cause-and-effect relationship.
Option C uses a misplaced modifier, suggesting that the means are given to the perspectives, rather than to us.
Option D uses the subordinating conjunction "although," which suggests a contrast between two ideas rather than a cause-and-effect relationship.
Therefore, option B is the correct choice, which uses the coordinating conjunction "by" to express the cause-and-effect relationship, and the pronoun "us" to convey the effect. The sentence reads, "Language opens the door to other perspectives by giving us the means to apprehend other ways of viewing our common world and our common humanity."
Many of the courses in law schools today are purely theoretical exercises. These exercises have little to do with their initial purpose.- a)exercises that
- b)exercises, so they
- c)exercises; they
- d)exercises, being so these
Correct answer is option 'C'. Can you explain this answer?
Many of the courses in law schools today are purely theoretical exercises. These exercises have little to do with their initial purpose.
a)
exercises that
b)
exercises, so they
c)
exercises; they
d)
exercises, being so these
| | Rajeev Kumar answered |
The sentence presents a contrast between the current state of law school courses and their initial purpose. To correctly convey this contrast, we need to use a coordinating conjunction (such as "but" or "yet") and a pronoun (such as "they") to refer back to the subject "courses."
Option A is incorrect because it uses a relative pronoun "that" instead of a coordinating conjunction.
Option B is incorrect because it uses "so" incorrectly, as it suggests a cause-and-effect relationship between the two clauses.
Option D is incorrect because it uses the awkward phrase "being so these" instead of a coordinating conjunction.
Therefore, option C is the correct choice, which uses a semicolon to join the two independent clauses and the pronoun "they" to refer back to the subject "courses." The sentence reads, "Many of the courses in law schools today are purely theoretical exercises; they have little to do with their initial purpose."
