Read the following article and select the best answer. Article: Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea animals comes from a number of human activities. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land caused pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect. Some scientists have planned to set a noise limit of one hundred and twenty decibels in oceans. They have found that noises at that level can frighten and confuse whales. A team of American and Canadian scientists discovered that loud noises can seriously hurt some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected. Many researchers whose work depends on ocean sounds disagree to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to stop noises from harming creatures in the ocean. Question: We can know from the passage that many scientists think that the noise limit of one hundred twenty decibels would _ . - stop them from doing their research work - benefit them a lot in their research work - do good to their health - increase the industrial output
stop them from doing their research work

Read the following article and select the best answer. Article: Think stars don't move? Think again! When you look at the sky at night, the stars may appear to stay in the same place. But stars are always on the move--they are just so far away that the movement is hard to see. But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities . It was located on the outer edge of the Milky Way, the galaxy we live in. The star was speeding away like nothing he'd ever seen. "It seemed unbelievable. No star in the galaxy has a speed like that," Brown remembers. "I thought, oh my goodness, I have something kind of special here." No one had ever seen a star like this one. What does a scientist do when the results don't make sense? Brown didn't give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called _ stars. Hyper means "above" and velocity has to do with speed. He and his team just found six more of these "above speed" stars, bringing to the total of 16. And, he says, he's found even more, and is just waiting for the scientific community to confirm them. Question: The writer writes this passage to tell us _ . - something about an astronomer. - where the Milky Way is - something about the speedy stars. - how scientists do their research
something about the speedy stars.
