Question 1:
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 the most support for the prediction that the agencies' action will have its intended effect?
A. Ruffe generally feed at night, but most recreational fishing on the Great Lakes is done during daytime hours.
B. 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
C. The ruffe is one of several nonnative species in the Great Lakes whose existence threatens the survival of lake whitefish populations there.
D. The bait that most people use when fishing for whitefish on the Great Lakesis not attractive to ruffe.
