In parts of the Caribbean, the manatee, an endangered marine mammal, has long been hunted for its meat. Having noted the manatee hunters’ expert knowledge of manatees’ habits, local conservationists are encouraging the hunters to stop hunting and instead to take tourists on boat rides to see manatees. Tourist interest is high, so the plan has promise of achieving the twin goals of giving the former hunters a good income and helping ensure the manatees’ survival.

Which of the following, if true, raises the most serious doubt about the plan’s chance of success?
A. Many tourists who visit these parts of the Caribbean are uninterested in manatees
and would not be willing to pay what the former manatee hunters would have to
charge for boat rides to see manatees.
B. Recovery of the species would enable some hunting to continue without putting
the manatees’ survival in jeopardy again.
C. In areas where manatees have traditionally been hunted for food, local people
could easily replace the manatee meat in their diets with other foods obtained
from the sea.
D. There would not be enough former manatee hunters to act as guides for all the
tourists who want to see manatees.
E. To maintain their current income, manatee hunters who switched to guiding
tourists would have to use far larger boats and make many more trips into the
manatees’ fragile habitat than they currently do.

The key to this question is noticing the words 'twin goals.' The correct answer must show how both goals are being undermined.

(A) is a very alluring answer choice. After all, if tourists do not want to see the manatees then the plan of providing manatee tours falls apart. But remember, the conclusion is based on twin goals: 1. Giving hunters a good income 2. Ensuring manatee's survival. If many tourists are uninterested in manatees, then that doesn't completely compromise both goals. After all, some manatee tours may still carry on, albeit with mixed results and manatees may actually end up being less endangered than before (assuming that those manatee tour guides who are working won't be hunting).

(E) shows that the hunters will not receive a good income. Indeed, they will struggle to make the same amount as they were before. And by struggle, they will have to get a bigger boat and make more frequent trips, which will destroy the manatees habitat. Remember, the whole point of the plan was to protect the manatees. Now not only do you have financially struggling tour guides but you've further jeopardized the manatee population.

Hope that helps .

Premise - In parts of the Caribbean, the manatee, an endangered marine mammal, has long been hunted for its meat. Having noted the manatee hunters’ expert knowledge of manatees’ habits, local conservationists are encouraging the hunters to stop hunting and instead to take tourists on boat rides to see manatees.

Conclusion - Tourist interest is high, so the plan has promise of achieving the twin goals of giving the former hunters a good income and helping ensure the manatees’ survival.

Anything which weakens the conclusion is our answer

A)Many tourists who visit these parts of the Caribbean are uninterested in manatees and would not be willing to pay what the former manatee hunters would have to charge for boat rides to see manatees. (Wrong as it is already given in the passage that Tourist interest is high)
B) Recovery of the species would enable some hunting to continue without putting the manatees’ survival in jeopardy again. (Neutral statement)
C) In areas where manatees have traditionally been hunted for food, local people could easily replace the manatee meat in their diets with other foods obtained from the sea. (Rather than weakening it strengthens the conclusion, eliminate)
D) There would not be enough former manatee hunters to act as guides for all the tourists who want to see manatees. (Not relevant)
E) To maintain their current income, manatee hunters who switched to guiding tourists would have to use far larger boats and make many more trips into the manatees’ fragile habitat than they currently do (This is our answer, if the incentives the hunters receive as tourist guides is less or the trouble is more they might not switch the occupation)

Yes E it is because it attacks of both the scenarios.

A- Defeats one of the 2 goals that are part of the conclusion – A negative effect on the income of manatee hunters.
B- Does not cast serious doubt on the conclusion of the above argument. In fact “B” is completely removed from the scope of the argument.
C- Absolutely irrelevant
D- Strengthens the argument.
E- Correct as “E” goes a step further than “A” and defeats the other goal of safeguarding the manatees.

A- is a very attractive choice but if you ready carefully, it actually goes against the premise stated in the argument .

E - is the best answer as they would not be able to maintain their former levels of income.

Great example of a question where one can too quickly get convinced of answer A and therefore doesn't read precise enough until the end. Great lecture for me. Clearly E is much better than A.

Thank you guys
