Directions: Five sentences A, B, C, D, and E are given below, you need to rearrange the sentences so that the five sentences can together form a meaningful paragraph.

A. We breathe polluted air, drink polluted water and eat polluted food.
B. Rising pollution is a very big problem for us.
C. The question is rising how can we protect ourselves from this enemy.
D. It is producing health challenges for all.
E. Pollution produces many health challenges not only for all creatures but also for our environment.

Which of the following should be the SECOND sentence after rearrangement?

The correct option is D.

To find the second sentence after rearrangement, let us analyze the logical flow of the given sentences:

1. Sentence B ("Rising pollution is a very big problem for us.") introduces the main subject—pollution as a major problem. Thus, it serves as the introductory or FIRST sentence.
2. Sentence D ("It is producing health challenges for all.") follows B logically by expanding on the primary consequence of pollution using the pronoun "It" (which refers back to "pollution" in B). Therefore, D is the SECOND sentence.
3. Sentence A ("We breathe polluted air, drink polluted water and eat polluted food.") elaborates on how it creates health challenges in our daily lives. This forms the THIRD sentence.
4. Sentence E ("Pollution produces many health challenges not only for all creatures but also for our environment.") broadens the scope of the problem to environment and creatures, making it the FOURTH sentence.
5. Sentence C ("The question is rising how can we protect ourselves from this enemy.") poses a concluding question on how to tackle the issue, serving as the FIFTH (final) sentence.

The complete coherent paragraph is: B - D - A - E - C.

Hence, the SECOND sentence after rearrangement is D.
