Sentences of a paragraph are given below in jumbled order. Arrange the sentences in the correct order to form a meaningful and coherent paragraph.
1) Nitrogen must go through changes akin to those that food goes through in our digestive system before plants may absorb life from the atmosphere.
2) Nitrogen needs to be transformed because it is insoluble and useless in its airborne state.
3) Lightning initiates the chain of chemical processes that must take place for nitrogen to replenish our planet.
4) There are over 22 million tonnes of nitrogen floating over each square mile of the globe, which is a plentiful resource and a necessary meal for plants.
5) Lightning is one of nature's most striking instances of a bad wind blowing good.

  • A.5 4 3 1 2
  • B.5 3 4 2 1
  • C.3 5 4 1 2
  • D.3 5 2 1 4

Answer: B

The order is 5 3 4 2 1. Sentence 5 introduces lightning as an example of a bad wind blowing good. Sentence 3 says lightning starts the chain of chemical processes for nitrogen. Sentence 4 states that there is much nitrogen in the air, sentence 2 says it must be transformed because it is useless in its airborne form, and sentence 1 says what that change is like. Orders that begin with 3 or put 4 before 3 do not follow this chain of ideas.
