Q: Read the following article and answer the question. Article: If music makes you smarter, and exercise helps brain function, can exercising to music really boost brainpower? Some researchers said it could. Volunteers who listened to Vivaldi~ "Four Seasons" while working out on a treadmill did much better on a test of verbal ability than when they exercised without music, a team at prefix = st1 /OhioStateUniversityfound. "Evidence suggests that exercise improves the cognitive performance of people with coronary artery disease ," said psychologist Charles Emery, who led the study. "And listening to music is thought to enhance brainpower. We wanted to put the _ together," Emery added in a statement. Writing in the latest issue of the journal Heart & Lung, Emery and colleagues said they studied 33 men and women taking part in a cardiac rehabilitation program after having bypass surgery, angioplasty or other procedures to treat clogged arteries. The volunteers said they felt better emotionally and mentally after working out with or without the music. But their improvement on the verbal fluency test doubled after listening to music on the treadmills ."Exercise seems to cause positive changes in the nervous system, and these changes may have a direct effect on cognitive ability," Emery said. "Listening to music may influence cognitive function through different pathways in the brain. The combination of music and exercise may stimulate and increase cognitive arousal while helping to organize cognitive output." Emery said he now wanted to test people using music of their own choice. "We used The Four Seasons' because of its moderate tempo and positive effects on medical patients in previous research," Emery said. "But given the range of music preferences among patients, it's especially important to evaluate the influence of other types of music on cognitive outcomes." Question: We can infer that Emery's next step will be Answer:

OPTIONS:
- to let the volunteers to listen to music of their own choice
- to choose volunteers of different ages
- to let the volunteers to listen to moderate tempo music
- to test whether music can help recovery

A: to let the volunteers to listen to music of their own choice

Problem:OPTIONS:
- Whales are in danger because of the noise.
- Noise pollution is affecting whales.
- Natural noise is good for whales.
- How to protect whales endangered.

Read the following article and answer the question. Article: If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do? Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately, man-made noise from oil and gas drilling, sonar, and ships is also present. Low frequency noise has doubled off the California coast every decade since the nineteen sixties. The main reasons are ships' propellers . They not only generate continuous low frequency sound, some propellers cavitate , which means they create air bubbles that collapse, creating loud popping sounds. Whales use low frequency calls to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the water, are the most at risk. Scientists studying right whales off Canada's east coast have discovered that whales are sending louder calls through the water to make themselves heard. Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area. This could seriously affect survival of this already threatened species. Scientists don't have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels, they are creating sound maps. They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas most important to the whales. Question: What does the passage mainly talk about? Answer:
****
A:
Noise pollution is affecting whales.
