From 1000CR doc
Though many insects die soon after reproducing for the first time, some may live for years after the survival of the next generation has been secured. Among the latter are some insects that work for the benefit of the ecosystemâ€”for example, bees.
Which one of the following can be properly inferred from the information above?
(A) Survival of the species, rather than of the individual, is the goal of most insect populations.
(B) Insects that do not play a vital role in the ecosystem are more likely to dies after reproducing for the first time.
(C) Most bees live well beyond the onset of the generation that follows them.
(D) Those bees that reproduce do not always die soon after reproducing for the first time.
(E) Most insects are hatched self-sufficient and do not need to be cared for by adult insects.
B Insects that do not play a vital role in the ecosystem are more likely to dies after reproducing for the first time.
B is wrong because only one of the groups that stay alive are the ones that play a vital role in the ecosystem which implies there are other groups that dont play a vital role but live beyond reproducing
a) Cannot be inferred
c) Out of scope
d) Out of scope
e) Out of scope
We need to infer the assumption to supports the conclusion. If the "next generation" of insects has been secure, then there is no need for the "parents" to continue to live since they have fulfilled their purpose (sad isn't it). The best answer is B which can be inferred from the stimulus.
Should this not be B. Argument states that - Among the latter(ie one's that survive to ensure the survival of the next geenration) work for the benefit of the ecosystem. Therefore the insects likely to die would be those that do not play an important role in ecosystem ... which is choice B..
I got D.
let's see how I got that.
A. it is infering too much. going out of scope
B. it never says that, it simply says that some insects that survive after reproducing for the first time, can be useful to ecosystem. Probably some are not useful as well. the ones that die, some of them can be useful as well...no information has been provided regarding that.... so it is out.
C. See the word "May" that means bees may or may not survive...
D. This one is exactly what we can infer. some bees may die, but some survives, that can be surely infered from the argument.
E. is out of scope.
D here. "Those bees that reproduce do not always die soon after reproducing for the first time." => exactly as the premise states that some bees live well beyond the survival of the next generation, and not necessarily die after reproducing, although some bees do.
