Several people have died while swimming during high water on Yangzi River near Wuhan in recent years. The Wuhan police department has proposed a ban on swimming when the river reaches flood stage. Opponents of the ban argue that the police should ban an extreme sport only if it harms people other than those participants of the sport, and therefore conclude that that the proposed ban is unwarranted.

Which of the following, if true, most seriously weakens the opponent’s conclusion?

A) Statistics provided by the Chinese Health Department show that fewer people drown on rivers with high water swimming bans than on rivers without such bans.

B) Participants of extreme sport are, on average, more likely to take risks and behave recklessly.

C) Several Wuhan police officers have been injured while attempting to rescue swimmers who became exhausted on the Yangzi River while swimming in high water.

D) When risks are involved in a sporting activity, it is the participants who should bear the blunt of the potential harm.

E) It is within the authority of the police to ban any activities they deem dangerous to people.

这道题同上一题，都是问错误前提假设的。       原因：只要禁止使别人受伤的极限运动就好了   结论：规定无效                 这个错误前提假设很有跳跃思维啊。。。。说有些官员受伤是因为救人。。。   脑子要转弯几次的考题一般真题里不会出现吧

A only if B --> If A, then B; NOT if B, then A

Opponents of the ban argue that the police should ban an extreme sport only if it harms people other than those participants of the sport

the police should ban an extreme sport =A
it harms people other than those participants of the sport=B
A only if B → if B，then A

so answer C  give evidence to B

right?

thank u!

A logic conclusion.  Bravo.

You guys rock!  The answer is C, in which someone other than the participants of the sport have been and could be hurt due to the swimming in high water.  It definitely removes a pillar underneath the opponent's argument.
