61. A milepost on the towpath read "21" onthe side facing the hiker as she approached it and "23" on its back. She
reasoned that the nextmilepostforward on the path would indicate that she was halfway between one end of
the path and the other. However, the milepost one mile further on read "20" facing her and "24" behind .
Which of the following, if true , would explain the discrepancy described above?
(A) The numbers on the next milepost had been reversed.
(8) The numbers on the mileposts indicate kilometers, not miles.
(e) The facing numbers indicate miles to the end of the path, not miles from the beginning.
(O) Amilepost was missing between the two the hiker encountered.
(E) The mileposts had originally been put in place for the use of mountain bikers, not for hikers.
62. In response to viral infection, theimmune systems of mice typically produce antibodies that destroy the virus by
binding to proteins on its surface. Mice infected with a herpesvirus generally develop keratitis, a degenerative
disease affecting part of the eye. Since proteins on the surface of cells in this part of the eye closely resemble
those on the herpesvirus surface, scientists hypothesize that these cases of keratitis are caused by antibodies
to herpesvirus.
Which of the following, if true, gives the greatest additional supportto the scientists' hypothesis?
(A) Other types of virus have surface proteins that closely resemble proteins found in various organs of mice.
(8) There are mice that are unable to form antibodies in response to herpes infections, and thesemice
contract herpes at roughly the same rate as othermice.
(e) Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as
infected mice that do develop keratitis.
(D) There are mice that areunable to form antibodies in response to herpes infections, and these mice
survive these infections without ever developing keratitis.
(E) Mice that have never been infected with a herpesvirus can sometimes develop keratitis.
63. Traditionally, decision making by managers that is reasoned step-by-step has been considered preferable to
intuitive decision making. However, a recent study found that top managers used intuition significantly more than
did most middle- or lower-level managers. This confirms the alternative view that intuition is actually more
effective than careful, methodical reasoning.
The conclusion above is based onwhich of the following assumptions?
(A) Methodical, step-by-step reasoning is inappropriate for making many real-life managementdecisions.
(8) Top managers have the ability to use either intuitive rea soning or methodical, step-by-step reasoning in
making decisions .
(e) The decisions made bymiddle- and lower-level managers can be made as easilyby using methodical
rea soning as by using intuitive reasoning.
(0) Top managers use intuitive reasoning in making the majority of their decisions.
(E) Top managers are more effective at decision making than middle- or lower-level managers.
64. High levels of fertilizer and pesticides, needed when farmers try to produce high yields of the same crop year
after year, pollute water supplies. Experts therefore urge farmers to diversify their crops and to rotate their
plantings yearly.
To receive governmental price-supportbenefits for a crop, farmers must have produced that same crop for the
past several years.
The statements above, if true, best support which of the following conclusions?
(Al The rules for governmental support of farm prices work against efforts to reduce water pollution.
(B) The only solution to the problemof water pollution from fertilizers and pesticides is to take farmland out of
production.
(e) Farmers can continue to make a profit by rotating diverse crops, thus reducing costs for chemicals, but
not by planting the same crop each year.
(D) New farming techniques will be developed to make it possible for farmers to reduce the application of
fertilizers and pesticides.
(E) Governmental price supports for farm products are set at levels that are not high enough to allowfarmers to get out of debt.

The following editorial appeared in the Elm City paper.
“The construction last year of a shopping mall in downtown Oak City was a mistake. Since the mall has opened, a number of local businesses have closed, and the downtown area suffers from an acute parking shortage, and arrests for crime and vagrancy have increased in the nearby Oak City Park. Elm City should pay attention to the example of the Oak City mall and deny the application to build a shopping mall in Elm City.” |
