Which of the following most logically completes the argument below?

When mercury-vapor streetlights are used in areas inhabited by insect-eating bats, the bats feed almost exclusively around the lights, because the lights attract flying insects. In Greenville, the mercury-vapor streetlights are about to be replaced with energy-saving sodium streetlights, which do not attract insects. This change is likely to result in a drop in the population of insect-eating bats in Greenville, since __________.

提问唐老师，这个题我只看了population of insect eating bats. 这样对吗？我在B和D中犹豫了一下，因为觉得B的重心在讲bat吃的虫子种类，所以干掉后选的D. 不知道如何可以直接选对D

Meat from chickens contaminated with salmonella bacteria can cause serious food poisoning. Capsaicin, the chemical that gives chili peppers their hot flavor, has antibacterial properties. Chickens do not have taste receptors for capsaicin and will readily eat feed laced with capsaicin. When chickens were fed such feed and then exposed to salmonella bacteria, relatively few of them became contaminated with salmonella.

In deciding whether the feed would be useful in raising salmonella-free chicken for retail sale, it would be most helpful to determine which of the following?

Art restorers who have been studying the factors that cause Renaissance oil paintings to deteriorate physically when subject to climatic changes have found that the oil paint used in these paintings actually adjusts to these changes well. The restorers therefore hypothesize that it is a layer of material called gesso, which is under the paint, that causes the deterioration.

Which of the following, if true, most strongly supports the restorers' hypothesis?

提问唐老师，选项D错误是因为讲的是gesso是个material而没有讲出题干中所说的gesso是原因吗？选项A仔细读觉得讲的是原因，可是无法迅速判定A和D

Archaeologists working in the Andes Mountains recently excavated a buried 4,000-year-old temple containing structures that align with a stone carving on a distant hill to indicate the direction of the rising sun at the summer solstice. Alignments in the temple were also found to point toward the position, at the summer solstice, of a constellation known in Andean culture as the Fox. Since the local mythology represents the fox as teaching people how to cultivate and irrigate plants, the ancient Andeans may have built the temple as a religious representation of the fox.

Which of the following is an assumption on which the argument is based?

提问唐老师，根据问题看了题干最后一句。概括成：因为狐狸教人们农业所以大家建庙来代表狐狸。我选择了D,因为觉得和农业而且和庙有关。虽然觉得选项D提了structure of temple 有点无关，但是觉得其他选项更无关

Tiger sharks are common in the waters surrounding Tenare Island.  Usually tiger sharks feed on smaller sharks, but sometimes they have attacked tourists swimming and surfing at Tenare's beaches.  This has hurt Tenare's tourism industry, which is second only to its fishing industry in annual revenues.  In order to help the economy, therefore, the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of the beaches.
 
Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence?
提问唐老师，这个题看了问题是要读最后一句话还是读the mayor proposed that 后面的内容？我只读了proposed 后面的内容，讲的是杀tiger sharks,而选项A直接接着话茬讲的，所以选了A. 请问正确思路是什么？以及我的思路错在哪里

The prairie vole, a small North American grassland rodent, breeds year-round, and a group of voles living together consists primarily of an extended family, often including two or more litters.  Voles commonly live in large groups from late autumn through winter; from spring through early autumn, however, most voles live in far smaller groups.  The seasonal variation in group size can probably be explained by a seasonal variation in mortality among young voles.
 
Which of the following, if true, provides the strongest support for the explanation offered?

Regulations will not allow a pesticide that is toxic to humans to be used inside houses unless the pesticide will dissipate completely from the air within eight hours after its application.  One test that pesticide manufacturers standardly use to determine how quickly anti-termite pesticides dissipate involves spraying the pesticides on the walls of room-sized plywood boxes and then timing its dissipation.
 
Which of the following would it be most useful to know in order to evaluate whether a dissipation time of just under eight hours on the manufacturers' test indicates that an anti-termite pesticide that is toxic to humans obeys regulations for use in houses?
