I'm taking a test and have to guess the right answer to the question after the article. Article: Redwood trees are the tallest plants on the earth,reaching heights of up to 100 meters.They are also known for their longevity,typically 500 to 1000 years,but sometimes more than 2000 years.A hundred million years ago,in the age of dinosaurs,redwoods were common in the forests of a much more moist and tropical North America.As the climate became drier and colder,they declined to a narrow strip along the Pacific coast of Northern Califomia. The trunk of redwood trees is very strong and usually forms a single straight column.It is covered with a soft bark.This bark can be pretty thick,well over two feet in the more mature trees.It gives the older trees a certain kind of protection from insects,but the main benefit is that it keeps the center of the tree harmless from moderate forest fires because of its thickness.This fire resistant quality explains why the giant redwood grows to live that long.While most other types of trees are destroyed by forest fires,the giant redwood actually prospers because of them. Moderate fires will clear the ground of competing plant life,and the rising heat dries and opens the ripe fruit of the redwood,releasing many thousands of seeds onto the ground below. New trees are often produced from shoots,little baby trees,which form at the base of the trunk.These shoots grow slowly,fed by the root system of the "mother'' tree.When the main tree dies,the shoots are then free to grow as full trees,forming a "fairy ring" of trees around the original tree.These trees,in turn,may give rise to more shoots,and the cycle continues. Question: Which of the following is a function of the tree bark as mentioned in the passage? Options: A: It allows redwood trees to bear seeds. B: It prevents redwood trees from attack by insects. C: It helps redwood trees absorb water in the air. D: It makes redwood trees more beautiful and appealing.

I'm taking a test and have to guess the right answer to the question after the article. Article: Fish species are expected to shrink in size by up to 24% because of global warming, say scientists. The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected. The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish's body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size. The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth's poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future." Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans. When compared with actual observations of fish sizes, the model seems to _ what's actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted. Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously... Question: We can infer that as ocean temperatures increase _ . Options: A: more big fish will be born in the sea B: fish tend to swim towards the shore C: fish tend to move towards the warm areas D: fish tend to move towards the colder areas

I'm taking a test and have to guess the right answer to the question after the article. Article: As a parent, you might never guess all the ways a good imagination benefits your child. It helps a preschooler. Develop social skills As children play pretend, they explore relationships between family members, friends and co-workers and learn more about how people interact. Playing doctor, they imagine how physicians care for their patients. Playing house, they learn more about how parents feel about their children. Imaginative play helps develop empathy for others. If children can imagine how it feels to be left out of a game or to lose a pet, they are better able to help those in need. They become more willing to play fair, to share, and to cooperate. Build self-confidence Young children have very little control over their lives. Imagining oneself as a builder of skyscrapers or a superhero defending the planet is empowering to a child. It helps them develop confidence in their abilities and their potential. Boost intellectual growth Using the imagination is the beginning of abstract thought. Children who can see a king's castle in a mound of sand or a delicious dinner in a mud pie are learning to think symbolically . This skill is important in school where a child will have to learn that numerals symbolize groups of objects, letters symbolize sounds, and so on. Practice language skills Kids who play pretend with their friends do a lot of talking. This helps boost their vocabulary, improve sentence structure and promote communication skills. Work out fears Playing pretend can help children work out their fears and worries. When children role-play about the big, bad monster under the bed, they gain a sense of control over him and he doesn't seem quite so big or so bad. Imaginative play also helps kids vent confusing feelings they might have, such as anger toward a parent or compete with a new sibling . To encourage your youngster's imagination, read to him every day. Books offer children the opportunity to visit other worlds and create new ones of their own. For generations children have enjoyed... Question: What's the purpose of writing the article? Options: A: To tell readers the benefits of encouraging children's imagination. B: To introduce some wonderful Disney stories to readers. C: To provide ways of helping make kids more imaginative. D: To persuade parents to buy the Disney edition of Peter Pan.
