Tiger sharks are common in the waters surrounding Tenare Island. Usually tiger sharks feed on smaller sharks, but sometimes they have attacked tourists swimming and surfing at Tenare's beaches. This has hurt Tenare's tourism industry, which is second only to its fishing industry in annual revenues. In order to help the economy, therefore, the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of the beaches.

Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence?

(A) Even if not all the tiger sharks that come close to the beaches are killed, the existence of the program would reassure tourists.
(B) Business owners who depend on tourism are willing to pay most of the cost of implementing the program.
(C) Tourists come to Tenare Island for its beaches, even though the island features a number of other tourist attractions.
(D) The small sharks on which tiger sharks prey feed on fish that are commercially important to the island's fisheries.
(E) Not all tourists who come to Tenare Island enjoy swimming or surfing.

If we rewrite this stimulus, then it may be .

Tiger sharks Usually feed on smaller sharks and sometimes attack tourists -when tourists swim at Tenare's beaches. This "attack" hurts Tenare's tourism industry that is second annual revenue producing source in relation to fishing industry. To help the economy, therefore, the mayor offered a program to kill any tiger sharks within a mile of swimming areas of the beaches.

Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence?

For which of the following, mayor's program may not be better suited for helping economy or increasing revenue?

As per my understanding in weakening question ,action is firstly to find the alternative-----show the relationship is reverse- and------secondly to prove the coclusion is not tenable.

however, here you can use any of them, because you have to show that the program will not bring intended result in helping economy by increasing revenue.

(A) Even if not all the tiger sharks that come close to the beaches are killed, the existence of the program would reassure tourists.----here this support the argument. because this ensures the potential tourists advent, thereby causing huge revenue. this show that the mayor program still best suited for its achieving goal-to increase revenues.
(B) Business owners who depend on tourism are willing to pay most of the cost of implementing the program. who will bear the cost of the program is not our concern. but the concern is to whether the program will be successful for achieving revenue or not.though it indirectly support the argument, it does not tell the success of the program.
(C) Tourists come to Tenare Island for its beaches, even though the island features a number of other tourist attractions. it may be that the main tourist attractions are to swimming and surfing in Tenare beaches rather than Tenare Island attracting features. this event produces huge revenue, but tiger shark causes hurt these tourists, tourists will not come again and dispense a dire feelings among potential roamers. this will hurt revenue, so this program must be implement for certaining the economy from the losses. this is strenthening the argument not weakening the argument. but if you say, this option is irrelevant, i will not absolutely disagree with you......
(D) The small sharks on which tiger sharks prey feed on fish that are commercially important to the island's fisheries.
(E) Not all tourists who come to Tenare Island enjoy swimming or surfing. this entails some possibilty for some tourists to be attacked by the tiger sharks if they swim in the beaches.-----what the stimulus says ----but sometimes they have attacked tourists swimming and surfing at Tenare's beaches.----------it says tourists swimming and surfing, here swimming and surfing modifies the tourists who are in the beaches for tiger shark's reach. so you can not attack the argument by the same line from the stimulus. and it also true that if some of tourists be attacked by the tiger sharks, other tourists will not be motivated to visit this beaches, i think they will disseminate the bad experience from the beaches to their close one or potential visitors to the beaches.



in D what it says ? our concern is to weaken the program that will not bring intended result in increasing revenues, ok?
D says----
tiger shaks feed small shark
small shark feed fish
fish are first revenue producing industry in Tenare
: if the program be succeed , then small sharks will easily feed on the fish that is 1st revenues generating sector in the beaches, causing negative impact on the economy
: if the program is not be succeeded , the small sharks will be reduced in number and feed on fish,this event will increase the fish and revenue for tenare.

be care when reading a sentence having modifiers...........i will also appear for the exam same date to your

[quote="asax"]Opps i got this wrong. I chose E. I didnt understand D at first, i thought Tiger Sharks are feeding small sharks, with careful reading found out, it is not so!

My take away from HeyGMAT's Explanation - To be careful while choosing options with some,not many, a few sort of wordings. This one is going to my exception list! +1 to you HeyGMAT!



thanks for recalling adverb but dire word choices----some, none, all,most............

The Tenare Island is famous because of 2 things:

- Beaches where the tourists go swimming and surfing
- Fishing activities here

If the tiger sharks did not existed near the beaches, this species would not control the smaller sharks, the main hunter of fish that is important factor to attract tourism.

So, the conclusion (Killing the tiger sharks to help the economy) will be collapsed.
