Topic: Ordering of sentences

Directions · Q21 to Q25

In this section each item consists of six sentences that comprise a passage. The first and sixth sentences are given in the beginning as S1 and S6. The sequence of the middle four sentences has been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly on the answer sheet.

Q21

S1: Although all sources of energy ultimately come from natural processes, non-renewable resources cannot be replaced naturally at the rate they are being used.

S6: The sustainable use of natural resources in a manner that provides the maximum benefit of these resources to humans over a period of time can be termed as conservation.

P: This will increase the time and cost of mining and once these resources are used up they cannot be replaced.

Q: Hence, we must remember that though our country is rich in mineral deposits these resources are short-lived.

R: Extraction of these ores through the process of mining will soon become difficult and very expensive because these minerals have to be mined from greater depths over time.

S: Mineral resources can be said to be finite and non-renewable.

  2. (b) SPQR
  3. (c) SQRPCorrect answer
  4. (d) SQPR

Solution.

Answer: (c) SQRP

  1. S introduces mineral resources as an example of the non-renewable resources in S1. Q draws the warning that even rich deposits are limited.
  2. R then explains the increasing difficulty of extraction, and P follows because “This” refers to mining at greater depths.
  3. S6 moves to conservation as the response.
  4. The complete sequence is S1–S–Q–R–P–S6.
  5. In particular, R must precede P to supply the cause of increased mining time and cost.
