I'm taking a test and have to guess the right answer to the question after the article. Article: Fencing or Not Wildlife fences are constructed for a variety of reasons including to prevent the spread of diseases, to protect wildlife from poachers , and to help manage small populations of threatened species. Human-wildlife conflict is another common reason for building fences. Wildlife can damage valuable farm animals and crops. Some species carry diseases of agricultural concern, and a few threaten human lives. At the same time, people kill wild animals for food, trade, or to defend lives or property, and human activities destroy wildlife habitat . Separating people and wildlife by fencing can appear to be a _ beneficial way to avoid such harmful effects. But in a paper in the journal Science, published recently, some scientists argue that fencing should only be used if worse comes to worst. According to the scientists, although fencing can have conservation benefits, it also has costs. When areas of wildlife habitat are changed into islands, the resulting small and isolated populations tend towards extinction, and the resulting loss of larger-bodied species can affect interactions between species in ways that cause further local extinctions. Therefore, scientists are asking that conservationists carefully weigh up the biodiversity costs and benefits of new and existing fences. In addition to fences' ecosystem-wide impact, the scientists don't think they always achieve their specific aims. Construction of fences to reduce human-wildlife conflict has been successful in some places but the challenges of appropriate fence design, location, construction, and protection mean that fences often fail to deliver the anticipated benefits. In some places, fences also provide poachers with a ready supply of wire for making traps. A variety of alternative approaches, including better caring for farm animals, community-based crop-guarding, insurance and wildlife-sensitive land-use planning are suggested to reduce conflicts between people and wildlife without the need for fencing. Some projects working with local... Question: The main purpose of the passage is to   _  . Options: A: argue and prove B: inform and explain C: appeal and discuss D: compare and assess

I'm taking a test and have to guess the right answer to the question after the article. Article: A lot of people are afraid of spiders . One would even avoid walking in grass . And if he thought the spider was in the room or house, he would have to leave the house for days. In fact, fear of spiders is a type of disorder called specific phobia , one of the most common anxiety disorders, which annoys about 7% of the population, a study says. Common specific phobias also include fear of blood, needles, snakes, flying and enclosed spaces. The Northwestern University Feinberg School of Medicine tried the "exposure Therapy ", which was small, done on 12 adults, but all of them held or petted the spider afterward. One participant celebrated by getting a spider tattoo  after having been unable to even look at photos of spiders. This is the first study to document the immediate and long-term brain changes after treatment and to illustrate how the brain recognizes long-term to reduce fear as a result of the therapy.  Every one would come in thinking: I am going to be the one who can't do this . There is no way ,"Haunter ,author of the study ,says "They were impressed by the end." In therapy lasting two or three hours, which is different for each person, the participants were taught that troublesome thoughts about spiders were untrue." "They thought the spiders might be capable of jumping out of the cage and on to them," Hauner says. Exposure therapy gets its name from exposing a patient to what he fears, says Todd, research assistant professor: "A lot of it about dispelling people's beliefs. You can get significant changes in a short period of time". Question: According to Hauner ,  _  . Options: A: the therapy was completed ahead of time. B: the therapy removed the participant' fear. C: each participant doubted the therapy at first. D: spiders sometimes attacked the participants.
