Question : 45 of 120

Marks: +1, -0

Directions: In this section, each item consists of six sentences of a passage. The first sentences in each sentence are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labeled 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: The ecosystem of water is complex and many environmental factors are intricately linked.

S6: The trees slowly transfer rainwater into the sub-soil and this is critical for sustaining water for months after the rains.

P: Thick forests make for excellent catchments.

Q: The problems we see are because we have undermined these links over decades.

R: First, rain and snowfall are the only sources of water - about 99%.

S: In the four months of monsoon, there are about 30-35 downpours and the challenge is to hold this water in systems that can last us over 365 days.

The correct sequence should be:

Q, R, S, P
P, S, R, Q
S, R, Q, P
R, Q, S, P

Solution:

Concept:

Arranging jumbled sentences requires logical flow: from a general statement to specific details, cause, and solution.

Explanation:

S1 introduces the complex water ecosystem and linked factors.

Q directly follows: problems arise because these links have been ignored.

Next, R explains the primary water source: rain and snowfall (

99\%

).

S then describes the monsoon's

30-35

downpours and the challenge of storing water for

365

days.

Finally, P offers the solution: thick forests as excellent catchments, connecting to S6 about trees transferring water.

Answer:

Q, R, S, P (Option A).
