Read the following article and select the best answer. Article: Energy goes from one plant or animal to another.A food chain shows how this energy moves.Each time an animal gets eaten,its energy is passed onto the animal that eats it.The food chain is very important because it keeps the balance of nature.If one part of the food chain disappears,it can affect all the other plants and animals.Any threat to the food chain is a threat to the environment's biodiversity .The food chain helps keep animal populations in balance.However,if something happens to damage one of the links in the food chain,that balance is broken.If one animal becomes endangered,it puts all the animals above it at risk. Some of the threats are natural,such as wildfires,hurricanes,tornados,floods and so on.But the biggest threats to the food chain come from you and me.These threats include overfishing,logging,farming,development,pollution,etc.The food chain is endangered anywhere humans have had an effect on the natural environment. A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast.Canadian and American scientists say sharks are being killed in great numbers for their meat and fins .Now,not enough sharks are around to eat the cownose ray.The ray's population has increased and they have eaten up the shellfish to the point where it has hurt commercial fishing. Many of us disturb the natural environment in our own backyards.It's up to us to take care of the environment and try not to disrupt the natural food chain.If we don't act responsibly,animals will start disappearing. Question: We can infer that the writer wrote this passage mainly to _ . - explain what the food chain is - tell us something interesting about nature - suggest that we stop eating meat to save animals - suggest that we should not disrupt the natural food chain
suggest that we should not disrupt the natural food chain

Read the following article and select the best answer. Article: A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it. Some children reach eagerly for the treat they see. Some last a few minutes before they give in. But others are determined to wait until the last moment. By the time the children reach high school, something remarkable has happened. A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular, adventurous, confident and dependable. The children who gave in to temptation early were more likely to be lonely, easily frustrated and inflexible . Actually, the ability to delay reward is a sign of emotional intelligence which doesn't show up on an IQ test. The hardware of the brain and the software of the mind have long been scientists' concerns. But brain theory can't explain what we wonder about most, like the question why some people remain _ in the face of troubles that would sink a less resistant soul. Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting people's success, brain ability measured by IQ may actually matter less than the qualities of mind once thought of as "character". EQ is not the opposite of IQ. What researchers have been trying to understand is how they work together; how one's ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the ingredients for success, researchers now generally agree that IQ counts for about 20%; the rest depends on everything from social class to luck. While many researchers in this relatively new field are glad to see emotional issues finally taken seriously, some few fear EQ invites misuse. Question: Which of the following is TRUE of EQ and IQ according to the text? - There is no link between EQ and IQ. - The higher a person's IQ is, the higher his or her EQ is. - Some people can be blessed with lots of both, but some with little of either. - Scientists are trying to discover the way in which EQ and IQ work together.

Scientists are trying to discover the way in which EQ and IQ work together.
