Question
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. 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.
