Verbal Ability - Question Of The Day

The question below consists of a set of labelled sentences. All or some of these sentences when properly sequenced, form a coherent paragraph. Choose the most logical order of sentences from among the options.

1. This would result in column ozone losses to exceed 20% globally, 25-45% at mid-latitudes, and 50-70% at northern high latitudes persisting for 5 years, with substantial losses continuing for 5 additional years.

2. The nuclear winter scenario predicts that the huge fires caused by nuclear explosions would loft massive amounts of dark smoke and aerosol particles from the fires into the upper stratosphere.

3. These amounts would remain near or below 220 Dobson units at all altitudes even after three years, constituting an extra-tropical “ozone hole”.

4. They would absorb enough solar radiation to heat surrounding gases, setting in motion a series of chemical reactions that would break down the stratospheric ozone layer protecting the earth from harmful ultraviolet radiation.

5. Human health ailments like cataracts and skin cancer, as well as damage to plants, animals and ecosystems at mid-latitudes would rise sharply as ozone levels would decrease and allow more harmful UV light to reach Earth.

OPTIONS

1) CDEBA
2) BCDAE
3) BECAD
4) ADCEB
5) EBDAC
 
 
Solution


Statement B introduces the idea and the rest of the paragraph takes off from it. Eliminate options 1, 4 and 5.
Statement E talks about the ill effects of ozone layer depletion- an outcome of the issues presented in the passage.
Between options 2 and 3, option 2 has a better flow (in spite of not having all the 5 sentences).

Hence, the correct answer is option 2.
