The Eurasian ruffe, a fish species inadvertently introduced into North Americaâ€™s Great Lakes in recent years, feeds on the eggs of lake whitefish, a native species, thus threatening the lakesâ€™ natural ecosystem. To help track the ruffeâ€™s spread, government agencies have produced wallet-sized cards about the ruffe. The cards contain pictures of the ruffe and explain the danger they pose; the cards also request anglers to report any ruffe they catch.
Which of the following, if true, would provide most support for the prediction that the agenciesâ€™ action will have its intended effect?
A. The ruffe has spiny fins that make it unattractive as prey.
B. Ruffe generally feed at night, but most recreational fishing on the Great Lakes is done during daytime hours.
C. Most people who fish recreationally on the Great Lakes are interested in the preservation of the lake whitefish because it is a highly prized game fish.
D. The ruffe is one of several nonnative species in the Great Lakes whose existence threatens the survival of lake whitefish populations there.
E. The bait that most people use when fishing for whitefish on the Great Lakes is not attractive to ruffe.

WHat is the Conclusion in this CR question??

Look the sentences in red, the conclusion is implied: "The cards will help to track this fish".
In this case, we have to support that conclusion.

Hope it helps.

Hi gmatpunjabi,

Here the correct answer is C (" Most people who fish recreationally on the Great Lakes are interested in the preservation of the lake whitefish because it is a highly prized game fish. " ) as it offers some support to the government program.

I think the conclusion is given in the question.. the question asks "which of the following if true would provide most support for the PREDICTION THAT THE AGENCIES' ACTION WILL HAVE IT'S INTENDED EFFECT..."

The prediction is the conclusion IMO..

C is the answer .Here we need to find a reason for the anglers to report the catch of a raffe.It is correctly stated in C that since the anglers are interested in the whitefish they would surely report when a raffe is caught since the raffe is responsible for the reduction in whitefish population .

I think this is the conclusion.
