QUESTION
Five sentences are given below, labeled A, B, C, D and E. They need to be arranged in a logical
 order to form a coherent paragraph/passage. From the given options, choose the most appropriate
 option.
 A. The species, which are most numerous in individuals, will have the best chance of producing
 variations within any given period.
 B. Hence any rare species will be less quickly modified or improved within any given period, and
 they will be consequently beaten in the race for life by the modified descendants of the commoner
 species.
 C. From these considerations I think it inevitably follows, that as new species in the course of time
 are formed others will become rare and finally extinct.
 D. We have evidence of this in the fact that it is the more common species that afford the greatest
 number of varieties, or incipient species.
 E. Extinction or survival, therefore, is a function of a parameter that is totally beyond the control of
 the species.
 (a) ABCDE (b) ADBCE (c) BCAED (d) EDABC
ANSWER
b The entire paragraph talks about how extinction
occurs. Statements A, D and B all discuss how the
commoner species quickly overpower the more rare
ones. Statements E and C are conclusions based on
these statements. Mandatory pairs would be (A-D)
and (B-C).
