Nevertheless, about 150 nonstudents still use the library without paying. We will therefore gain financially if we hire a guard to identify nonstudents and ensure that they have paid the fee. Which of the following would it be most important to know in order to evaluate the librarians conclu- sion ? (A) The number of students who use the library annually. (B) The librarys budget this year. (C) Whether the library has installed an expensive computerized cataloging system. (D) How much the librarys budget was decreased three years ago. (E) The annual cost to the library of hiring a guard. 2. The first people to inhabit North America came from Asia. Scientists had hypothesized that these people traveled across a now-submerged landmass that connected the two continents until 14,000 years ago, depending for food only on the land animals they hunted as they traveled. Recent discoveries have led to the new hypothesis that the first people came by boat along the southern shore of the land- mass, eating fish and sea mammals. Which of the following, if true, most strongly supports the new hypothesis by casting doubt on the earlier hypothesis? (A) The landmass connecting North America and Asia extended very far to the north. (B) In Europe, maritime cultures primarily depen- dent on the sea for food developed no earlier than 10,000 years ago. (C) People living in Asia at the time the two conti- nents were connected hunted land animals for food. (D) The landmass was so bitterly cold that its vege- tation would have been too sparse to support land animals. (E) Sophisticated and mature cultures that display great similarities to each other existed as far back as 8,000 years ago in North America and Asia.
