The author implies that if, in the experiment described in the second paragraph, the parasitic wasps had been drawn to the plants after they had been damaged by a razor blade but without application of oral secretions from the caterpillar, then scientists would likely have concluded which of the following?

Parasitic wasps propagate by injecting their eggs into a caterpillar that then becomes paralyzed as the eggs inside develop into wasp larvae. The wasp larvae kill the caterpillar host as they feed on it, form cocoons, and finally develop into wasps. In attempting to discover how such wasps detect the presence of the caterpillar...

Which of the following, if true, provides the strongest reason for the manufacturer of Lorex not to challenge the chain’s use of the triangular package design?

Under United States law, a distinctive package design can be legally protected against copying. Lorex shampoo, a leading brand, is packaged in a triangular-shaped bottle with a gold label. A major pharmacy chain has introduced a similar, less expensive shampoo in similarly shaped bottles with plain black-and-white labels carrying the chain’s name. Though the...

Which of the following, if true, would most undermine the reasoning offered for the claim that gray markets can in certain conditions lead to increased profits among authorized retailers?

Manufacturers and retailers tend to look askance at gray markets, where products are sold at cut-rate prices outside their authorized distribution channels. Manufacturers fear that gray markets will undercut margins and tarnish brand names. Retailers fear that they will siphon away customers and erode prices. A new study indicates, however, that gray marketing actually...

Parasitic wasps propagate by injecting their eggs into a caterpillar that then becomes paralyzed as the eggs inside develop into wasp larvae. The wasp larvae kill the caterpillar host as they feed on it, form cocoons, and finally develop into wasps. In attempting to discover how such wasps detect the presence of the caterpillar hosts that are so critical to the wasps’ propagation, researchers have uncovered an intriguing defense mechanism developed by the plants on which the caterpillars feed.

Which of the following most accurately states the passage’s main point?

The decision as to when to bring charges for a criminal offense is the prerogative of the prosecutor, not the prospective defendant. This prerogative should not be put to unfair advantage. Sometimes decades elapse before charges are brought. Though this may be appropriate when striking new evidence implicates someone, bringing charges after many years...

According to the passage, the majority of the pairings observed in Sommer’s study exhibited postconflict affinity under what conditions?

Members of many primate species approach an opponent shortly after conflict and initiate behaviors such as embracing, grooming, or huddling―a phenomenon researchers call postconflict reconciliation. Existing research, however, suffers from several shortcomings. The variability between groups of the same species is rarely addressed; the majority of studies investigate only a small fraction of the...
