S1: Man has existed for about a million years. P: Science, as a dominant factor in determining the beliefs of educated men, has existed for about 300 years; as a source of economic technique, for about 150 years. Q: When we consider how recently it has risen to power, we find ourselves forced to believe that we are at the very beginning of its work in transforming human life. R: In this brief period it has proved itself an incredibly powerful revolutionary force. S: He has possessed writing for about 6,000 years, agriculture somewhat longer, but perhaps not much longer. S6: What its future effects will be is a matter of conjecture, but possibly a study of its effects hitherto may make the conjecture a little less hazardous. The Proper sequence should be: A. PQSR B. PRSQ C. RQPS D. SPRQ

[amp_mcq option1=”PQSR” option2=”PRSQ” option3=”RQPS” option4=”SPRQ” correct=”option1″]

The correct answer is: A. PQSR

The first sentence, S1, provides a general overview of the topic: man’s existence and his accomplishments. The second sentence, P, provides more specific information about one of man’s accomplishments: science. The third sentence, Q, provides a commentary on the significance of science. The fourth sentence, R, provides evidence to support the commentary in Q. The fifth sentence, S, provides additional information about man’s accomplishments. The sixth sentence, S6, provides a conclusion to the passage.

The following is a brief explanation of each option:

• Option A: PQSR
  This is the correct answer. The sentences are in the correct order, and the passage flows smoothly.
• Option B: PRSQ
  This option is incorrect. The sentences are not in the correct order. The first sentence, S1, should come before the second sentence, P.
• Option C: RQPS
  This option is incorrect. The sentences are not in the correct order. The first sentence, S1, should come before the third sentence, Q.
• Option D: SPRQ
  This option is incorrect. The sentences are not in the correct order. The first sentence, S1, should come before the fourth sentence, R.
