Premise : The naked mole rat is a pest to the farmers of Pellaville. The farmers plan to reduce the rat population by poisoning the stream out of which the mole rats drink.
Ques : Which of the following, if true, is the best support for the scheme of the farmers?
Pre-thinking : Wew need find the option which supports the farmer scheme that which supports the fact that by poisoning the stream out of which mole rats drink, rat population will reduce.
Lets analyse the options now :
(A) The poison that will be used in the stream is not toxic to the farmers' livestock -
Correct - This looks like a promising option. This mean only rats will be kileed and livestock will not be affected by the poison.
(B) The naked mole rat is not susceptible to most conventional poisons -
Incorrect - We need to find an option that strengthens the argument, if this is true for the poison that farmers are using, it will weaken the farmers plan.
(C) The befurred vole, a relative to the naked mole rat, is most effectively controlled with contraception rather than with poison -
Incorrect - This is totally irrelavant and not related to the passage in nay way.
Irrelevant.(D) The poison to be used is less expensive than other poisons -
Incorrect - We are not concerned about the price of the poison but whther the poison will effective in reducing rats population.
Irrelevant.(E) The poison will be most effective if administered after the harvest -
Incorrect - No information has been given that poison was administered before or after the harvet. Hence, the does not affect the farmers plan in any way. If it is administered before the harvest, less rats will be killed and if it is administered after, more rate will be killed.
In either way, rats number will be reduced and farmers will acheive the plan.
