It is not, therefore P : that I pay a tribute Q : to conductors as a class R : with any feeling of unfriendliness S : to a particular member of that class The Proper sequence should be:

The correct answer is: A. PQRS

The sentence is about the speaker’s tribute to conductors as a class. The speaker is not paying this tribute with any feeling of unfriendliness to a particular member of that class. The sentence should be sequenced as follows:

1. It is not, therefore, that I pay a tribute to conductors as a class.
2. With any feeling of unfriendliness.
3. To a particular member of that class.

The first sentence states the main point of the paragraph. The second sentence provides a reason for the main point. The third sentence provides an example of the main point.

Option B, RQPS, is incorrect because the second sentence comes before the first sentence. Option C, RSPQ, is incorrect because the third sentence comes before the second sentence. Option D, PSRQ, is incorrect because the third sentence comes before the first sentence.
