Some visitors to the park engage in practices that seriously harm the animals. Surely, no one who knew that these practices seriously harm the animals would engage in them. So it must be concluded that some of
the visitors do not know that these practices seriously
harm the animals.
The pattern of reasoning exhibited by which one of the
following arguments is most similar to that exhibited
by the argument above?

(A) Some of the people who worked on the failed project will be fired. Everyone in this department played an important part in that
project. Therefore some people in this department will be fired.

(B) Some of the people who signed the petition were among the mayor’s supporters. Yet the mayor denounced everyone who signed the
petition. Hence the mayor denounced some of her own supporters.

(C) Some of the people polled live outside the city limits. However, no one who can vote in city elections lives outside the city. Therefore some
of the people polled cannot vote in the upcoming city election.

(D) All of the five original planners are responsible for this problem. Yet none of the original planners will admit responsibility for the
problem. Thus some of the people responsible for the problem will not admit responsibility.

(E) Some members of the Liberal Party are in favor of the proposed ordinance. But all members of the city council are opposed to the proposed ordinance. Hence some members of the city
council are not Liberals. 26. Rapid population growth can be disastrous for a small city. Ideally there should be at least one municipal employee for every hundred residents; when too many people move in at once, city services responsible for utilities and permits are quickly overloaded. Most city budgets do not allow for the immediate hiring of new
staff.
