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 FOURTH sentence after rearrangement?

To find the correct order of the paragraph, let us analyze the given sentences logically:

1. Sentence B introduces the primary topic ("Rising pollution is a very big problem for us.") and serves as the opening sentence.
2. Sentence A follows by illustrating how pollution manifests in daily life ("We breathe polluted air, drink polluted water and eat polluted food.").
3. Sentence D points out the direct result of this pollution ("It is producing health challenges for all.").
4. Sentence E broadens the scope of these challenges ("Pollution produces many health challenges not only for all creatures but also for our environment."), making it the fourth sentence.
5. Sentence C concludes the paragraph logically by asking a question regarding protection from pollution ("The question is rising how can we protect ourselves from this enemy.").

Thus, the complete coherent sequence is B - A - D - E - C.

The fourth sentence after rearrangement is E.
