I'm taking a test and have to guess the right answer to the question after the article. Article: Normally, about 10 percent of the hair on your head is resting (not growing). After a few months, the resting hair falls out and new hair begins to grow in its place. The growing time can last from 2 to 6 years. During the growing period, hair will gain about 1 centimeter a month. It is normal to experience hair loss every day. Some people experience too much hair loss from a variety of causes. Most people _ believe that hair loss is caused by things like stress, scalp ,or wearing hats. With the exception of stress, none of these factors has been proven to be a cause of hair loss. Stress is also not very likely unless you have experienced extreme physical or psychological suffering. This hair loss also doesn't last long. The real cause of hair loss lies with hormonal problems. Hair loss occurs when male or female hormones are out of balance. An imbalance of hormones is usually genetic and cannot be cured. Male and female-pattern baldness is the most common form of hair loss. This is caused by a hormone called DHT, which helps in sexual development. An increase in DHT in a grown-up can lead to hair loss. There are also other causes of hair loss. Blood-thinners, some kind of medicines, and an excess of vitamin A, have all been shown to increase hair loss in certain people. Infections of the scalp can cause hair loss as well as certain diseases like diabetes. Question: What is this passage mainly about? Options: A: The side effects of medicines. B: The effects of hormones. C: The causes of hair loss. D: Some ways to protect your hair.

I'm taking a test and have to guess the right answer to the question after the article. Article: The deep sea is one of the most mysterious places on earth. Scientists rarely go there. Those few do discover new species all of the time. Many places of the deepest parts of the ocean, where it's forever dark, can light up. Now, a teen's research has shown new light on how one of these swimming animals behaves in darkness. The giant flashlight fish lives in the Indian Ocean as well as in tropical parts of the central and western Pacific. It lives at depths of up to 400 meters, (about 1,300 feet). But not always. Sometimes it lives in coral reefs in shallow waters. In those shallow waters, the blackish-blue fish comes out only at night. Reef-dwelling members of this species tend to be smaller than those living in deeper waters. Those biggies can grow to lengths of 35meters (14inches). That may not sound like a giant, but they are the largest of their type of fish. The giant flashlight fish gets its name from a small glow-in-the-dark patch found in a packet of tissue under each eye, explains Caroline Edmonds. She is a 13- year-old student from Fountain Valley, Calif. There, she attends Talbert Middle School. She said that the eye pockets in these fish contain light-producing bacteria. These bacteria and their host fish have built a relationship that helps both. The fish use the bacteria as a way to communicate with creatures around them. The bacteria gain nutrients from the fish and a safe place to live. When a fish wants to " flash" its light, it turns the bacteria-filled pocket toward the outside of its body, Caroline explains. When a fish wants to hide its light, it turns the pocket back toward the inside. According to her data, the fish flash most often when they are being fed. They flash least often late at night, when they are resting. Question: The deep sea is dark and mysterious, but _ Options: A: a teen's research is going to light it up. B: in the deepest part, lives a swimming animal. C: scientists are looking for a new species to light up. D: a kind of glowing fish has been found there.

I'm taking a test and have to guess the right answer to the question after the article. Article: "Can I get a light?" This question is among the most common between smokers. What if this question was to come from an unusual source? In April 2014, the National Health Promotion Foundation uploaded an anti-smoking advertisement onto YouTube. The anti-smoking ad has quickly been known as the "most powerful anti-smoking ad." The anti-smoking video, called the "Smoking Kid," features children walking up to adult smokers asking for a light. The children in the ad are actors but the adults smoking are _ participants in the project. The video begins with the statement "adults know that smoking is harmful, but don't remind themselves of this fact " Once a "smoking kid" approaches the adults, every adult asked is shocked that a child with a cigarette in hand is asking for a light. The first adult starts by saying, "I'm not giving it to you," and the video goes on to state "every adult filmed said no and reminded the children that smoking is bad." Before going away, the kid hands each adult a booklet after being turned down for a light. The booklet says, "You worry about me, but why not about yourself?" Each adult looks around for the child as their faces are filled with confusion and discomfort. The video shows that a few of the smokers quickly threw away their cigarettes or put their cigarettes away, showing that this experiment was affective at that moment. The most influential element in the ad isn't the use of children or the responses from the smoking adults. It comes down to something much simpler than that. Why is it that we worry about other people, forgetting to worry about ourselves? Question: According to the text, the anti-smoking ad is _ . Options: A: unusual B: shocking C: influential D: encouraging
