[問題] gwd 9-14
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.
請問c 哪理是支持阿
不是說為了要track the ruffe's spread 所以做了一堆事情
c是在講釣客的行為
我怎麼覺得是無關
謝
