In each of the following questions, two columns are

Solution

The correct pairs are AF, BE, and CD. AF - The adjective ISOLATED in A can modify the noun ISLAND SPECIES given in F. The sentence here seeks to convey that although the giant tortoise experienced more good and bad situations than the isolated island species, the bad situations that these tortoises experienced can turn out to be very dangerous for them. "The Aldabra giant tortoise experienced more ups and downs; but for isolated island species, downs can all too often prove catastrophic." BE - The connector AND used in B needs to connect the clause given before it with another clause to make a meaningful sentence. The clause given in E is suitable for it. The sentence here seeks to convey that animals that live longer face problems surviving, and giant tortoises are among these animals. "Animals that live for a long time take pains to avoid early death, and giant tortoises are among the longest-lived of all land animals." CD - We need a noun to function as an object of the preposition OF in C. The noun ONE'S SPECIES in D can fulfil this role. The sentence here seeks to convey that no matter what kind of life a particular species is destined to have, a creature's life is in his own hands. "Faced with the specific fate of one's species, life remains very much what you make it." Thus, C is the right answer.
