A paragraph has been provided. From the given options, choose the sentence that continues the paragraph in the most appropriate way.
Most significantly, Darwinian natural selection has helped researchers develop hypotheses for thinking about the process by which chemicals organise themselves into living forms. Natural selection, the process that shapes evolution, tells us that, as populations reproduce and change, those species best adapted to their environment survive. Many researchers think that natural selection can also explain the process by which inanimate matter begins to organise itself into living forms._________________
1.To anyone watching, it might seem like we'd need a set of parallel universes to test all of the alternatives.
2.If new species emerge by natural selection, then there might be prebiotic chemical precursors that become capable of evolution - perhaps evolution marks the beginning of life.
3.Indeed, scientists tackling the hard problem of life's origins have reached deep into the evolutionary past only to extend far beyond it.
4.Is life easy or hard?
5.More than one of the above
Correct Answer : 2
Solution :
The main theme of the paragraph is Darwinian natural selection.
Option (a) - Incorrect as it not related to the paragraph.
Option (b) - Correct as it concludes the paragraph by explaining how evolution marks the beginning of life.
Option (c) - Incorrect as it introduces the problem of life's origin but the paragraph does not talk about it.
Option (d) - Incorrect as it is not related to the paragraph.
Hence, (b) is correct.
