Read the following article and select the best answer. Article: On an elementary school playground, hundreds of children run and jump, smiling and laughing as they play. Watching sea otters playing in their own environment is like watching children at play. Sea otters, which are presently on the endangered species list, are experiencing an increase in population. Groups of sea otters live on the shores of the North Pacific Ocean. They are seldom found far from land but almost spend their entire lives at sea. The otter has been known to dive as deep as 180 feet and stay underwater as long as minutes. Each day the sea otter eats as much as one-fifth of its body weight in fish or shellfish. Not only are sea otters playful, they are also amazingly resourceful. Their favorite food, abalone , is protected by a thick shell that sea otters are unable to break with their teeth. Sea otters use stones from the ocean floor and break the abalone open on their bellies as they move slowly across the surface of the water on their backs, a behavior that makes them one of only a few animals on Earth, including human beings, to use tools! Their intelligence is also displayed while sleeping. In order not to move into dangerous waters, sea otters actually cover themselves with plants on the sea, which keep them in place before falling asleep. Because sea otters have a special means of keeping insulated , they can keep their body heat in their cold environment. They have unbelievably fine fur that traps tiny bubbles, and that keeps them comfortable when warmed by body heat. However, their fur loses this insulating quality if it becomes dirty. Sea otters have faced dangers from hunters in the past and from oil spills more recently. Fortunately, due to a 1911 agreement and to rescue and habitat protection efforts, the sea otter population has nearly recovered. Question: The author mentioned playful children at the beginning in order to _ . - show sea otters are fun to watch. - describe a scene where children play with sea otters. - compare children with sea otters. - discuss the problem faced by sea otters
show sea otters are fun to watch.

Read the following article and select the best answer. Article: Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation. Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth. Question: If a human being is hit by nuclear radiation, he may _ . - die of cancer after many years - die immediately - have a child who may be born weak - all of the above
(Answer)
all of the above
