7. all zebras have stripes, and the most widespread subspecies has the best-defined stripes. The stripes must therefore be of importance to the species. Since among these grassland grazers the stripes can hardly function as camouflage, they must serve as some sort of signal for other zebras.
Which one of the following, if true, most strongly supports the conclusion regarding a signaling function?
(A) The subspecies of zebras with the best-defined strips is also characterized by exceptional size and vigor.
(B) In certain tall grasses zebras can be harder to spot than grazing animals with a coat of uniform color.
(C) A visual signal transmitted among the members of a species can consist of a temporary change of color perceptible to other members of the species.
(D) Zebras react much faster to moving shapes that have stripes than they do to moving shapes that are otherwise identical but lack stripes
(E) Zebras have a richer repertoire of vocal signals than do similar species such as horses.

Consumer activist: By allowing major airlines to abandon, as they promptly did, all but their most profitable routes, the government's decision to cease regulation of the airline industry has worked to the disadvantage of everyone who lacks access to large metropolitan airport.
Industry representative: On the contrary, where major airlines moved out, regional airlines have moved in and ,as a consequence, there are more flights into and out of most small airports now that before the change in regulatory policy.
17. The industry representative's argument will not provide an effective answer to the consumer activist's claim unless which one of the following is true?
(A) No small airport has fewer flights now than it did before the change in policy regarding regulation of the airline industry.
(B) When permitted to do so by changes in regulatory policy, each major airline abandoned all but large metropolitan airports.
(C) Policies that result in an increase in the number of flights to which consumers have easy access do not generally work to the disadvantage of consumers.
(D) Regional airlines charge les to fly a given route now that the major airlines charged when they flew the same route.
(E) Any policy that leads to an increase in the number of competitors in a given field works to the long-term advantage of consumers.

21. In response to high mortality in area hospitals, surgery was restricted to emergency procedures during a five-week period. Mortality in these hospitals was found to have fallen by nearly one-third during the period. The number of deaths rose again when elective surgery (surgery that can be postponed) was resumed. It can be concluded that ,before the five --week period, the risks of elective surgery had been incurred unnecessarily often in the area.
Which one of the following, if true, most seriously undermines the conclusion above?
(A) The conclusions for which elective surgery was performed would in the long run have been life-threatening, and surgery for them would have become riskier with time.
(B) The physicians planning elective surgery performed before the five-week period had fully informed the patients who would undergo it of the possible risks of the procedures.
(C) Before the suspension of elective surgery, surgical operations were performed in area hospitals at a higher rate, per thousand residents of the area, than was usual elsewhere.
(D) Elective surgery is, in general, less risky than is emergency surgery because the conditions requiring or indicating surgery are often less severe.
(E) Even if a surgical procedure is successful, the patient can die of a hospital-contracted infection with a bacterium that is resistant to antibiotic treatment.
