In 1960's studies of rats, scientists found that crowding increases the number of attacks among the animals significantly.  But in recent experiments in which rhesus monkeys were placed in crowded conditions, although there was an increase in instances of "coping" behavior—such as submissive gestures and avoidance of dominant individuals—attacks did not become any more frequent.  Therefore it is not likely that, for any species of monkey, crowding increases aggression as significantly as was seen in rats.

Which of the following most logically completes the argument?
 
A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants.  Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert.  Possibly, therefore, the herb's high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ______.

Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migrations.  In the fall, they eat a significant portion of the province's sunflower crop.  This year Midland farmers sought permits to set out small amounts of poisoned rice during the blackbirds' spring stop in order to reduce the fall blackbird population.  Some residents voiced concern that the rice could threaten certain species of rare migratory birds.  Nevertheless, the wildlife agency approved the permits.
 
Which of the following, if true, most helps to justify the wildlife agency's approval of the permits, given the concerns voiced by some residents?
