The Eurasian ruffe, a fish species inadvertently introduced into North America�s Great Lakes in recent years, feeds on the eggs of lake whitefish, a native species, thus threatening the lakes� natural ecosystem. To help track the ruffe�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 agencies� 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.

Any thought?

IMO C (because all other answers are either irrelevant or out of scope)

A - irrelevant
B - Actually weakens by stating tht it is unlikely the alien predator (ruffe) wud be fished.
C - Till now only relevant option
D- This restates the premise of the main question stem
E- Weakens tht ruffe wud be fished /not relevant to the action of government agency to curb the existence of Ruffe.

Thus C, actually states that the local people treasure the Lake whitefish, and tht government is taking steps to enlighten people tht the existence of the native fish is endangered.

Hope the explanation helps.
Gearing up for the D-day.

The OA is C

My answer is also C, but I thought it might be to weak to support the main conclusion. Thanks for annakool's explanation! :)
