Directions : In this section each item consists of six sentences of which comprise a passage. The first and the sixth sentences are fixed in their position as S1 and S6. The middle four sentences have been jumbled up and labelled as P, Q, R and S. You are required to find out the proper sequence of the four sentences and mark your response accordingly on the answer sheet.
S1: Although all sources of energy commonly come from natural processes, non-renewable resources, are being rapidly depleted and at the rate they are being used.
S6: The sustainable use of natural resources in a manner that provides for resource needs for current resources for humans over a period of time can be termed as con- servation.
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 natural deposits these resources are not.
R: Extraction of these ores through the process of mining will soon become difficult and also expensive because these minerals are often located deep from greater depths over time.
S: Mineral resources can be said to be finite and non-renewable.

Key Points
- The passage discusses the depletion of non-renewable resources and the importance of conservation. We need to establish a logical flow from the introduction (S1) to the conclusion (S6).
- S1: Introduces the problem of non-renewable resources being rapidly depleted.
- Sentence S directly follows S1 by defining these resources more specifically: "Mineral resources can be said to be finite and non-renewable." This clearly elaborates on "non-renewable resources" from S1.
- Sentence Q logically follows S, acting as a reminder or consequence of the finite nature mentioned in S: "Hence, we must remember that though our country is rich in natural deposits these resources are not." This emphasizes their limited nature.
- Sentence R then explains a practical consequence of these finite resources being exploited: "Extraction of these ores through the process of mining will soon become difficult and also expensive because these minerals are often located deep from greater depths over time." This details why their depletion is a problem.
- Sentence P builds directly on R's point about difficulty and expense: "This will increase the time and cost of mining and once these resources are used up they cannot be replaced." The word "This" refers to the difficulty and expense mentioned in R. P also reiterates the non-renewable aspect.
- S6: Finally, S6 defines conservation, which is the solution to the problem discussed throughout S1, S, Q, R, and P.
- The correct sequence is SQRP.
Coherent paragraph after rearrangement:
"Although all sources of energy commonly come from natural processes, non-renewable resources, are being rapidly depleted and at the rate they are being used. Mineral resources can be said to be finite and non-renewable. Hence, we must remember that though our country is rich in natural deposits these resources are not. Extraction of these ores through the process of mining will soon become difficult and also expensive because these minerals are often located deep from greater depths over time. This will increase the time and cost of mining and once these resources are used up they cannot be replaced. The sustainable use of natural resources in a manner that provides for resource needs for current resources for humans over a period of time can be termed as conservation."
