Question

The five sentences (labelled 1,2,3,4, and 5) given in this question, when properly sequenced, form a coherent paragraph. Decide on the proper order for the sentence and key in this sequence of five numbers as your answer.
1.Before plants can take life from atmosphere, nitrogen must undergo transformations similar to ones that food undergoes in our digestive machinery.
2. In its aerial form nitrogen is insoluble, unusable and is in need of transformation.
3. Lightning starts the series of chemical reactions that need to happen to nitrogen, ultimately helping it nourish our earth.
4. Nitrogen - an essential food for plants - is an abundant resource, with about 22 million tons of it floating over each square mile of earth.
5. One of the most dramatic examples in nature of ill wind that blows goodness is lightning.

• A. 51324
• B. 23541
• C. 53421
• D. 12435

Answer 1

Answer: (C)

53421

Answer 2

The correct answer is (C):
5 begins the paragraph by talking about the importance of lightning. 3, which states that lightning starts the series of chemical reactions that need to happen to nitrogen, and ultimately helps it to nourish the earth, is a continuation of 5. 4 follows 3 by explaining how nitrogen nourishes the earth with its ubiquitous presence over each square mile on earth. 2 follows by describing that nitrogen, in its aerial form is insoluble and that it is in need of transformation. 1 complements 2 explaining how nitrogen must undergo transformation similar to the way that food undergoes transformation in our digestive machinery. The logical sequence is 53421.
