Article: Patients and doctors alike have long believed in the healing power of humor.It is claimed that humor not only affects patients' moods, but can actually help them recover faster. Several studies seem to support this.Patients in better spirits are known to have higher immune cell counts.Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies. Despite all this, many researchers are not convinced.They point out the fact that many sufferings have been known to disappear naturally, with or without a daily dose of laughter.They also say that while optimism in general does seem to be related to better health, it is hard to tell which comes first. Humor in times of stress, however, clearly makes us feel better.On one level, it takes our minds off our troubles and relaxes us.On another, it releases powerful endorphins, a chemical produced by your body that reduces pain. There are cases where the appreciation of a good joke is indeed directly related to a person's health.It can show, for example, whether a person has suffered damage to one particular area of the brain: the right frontal lobe . Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list.Subjects with normal brains usually chose endings that were based on a relatively complex synthesis of ideas.Subjects with specifically located brain damage, however, responded only to slapstick endings, which did not depend on a particular context.When pressed, the brain-damaged subjects saw the logic in the correct endings.They simply did not find them funny. Of course, humor is largely an individual matter.Next time your friend does not get one of your jokes, there is no need to accuse him of being a lamebrain.However, you might suggest that he lighten up--for the health of it. Question: Scientists had some people read jokes and asked them to choose the funniest endings from a list to confirm that _ . Yes or no, is the answer "a person suffering certain brain damage doesn't appreciate a good joke"?
No

Article: Water is the "life blood" of our earth. It is in every living thing. It is in the air. It runs through mountains and valleys. It forms lakes and oceans. Water is everywhere. Nature has a great water system. Rain water finds its way to streams and the oceans. Here at the mouth of a river there is much important plant and animal life. Pollution destroys this life, so we have to clean out streams and rivers. Man has to work with nature--not against it. Question: There is much plant and animal life at the _ . Yes or no, is the answer "mouth of a river"?
(Answer)
No

Ques: Article: Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the body--and the body from them--until they can be released at just the right spot. There are lots of ways to trigger this release, including changing temperature, acidity, and so on. But triggers can come with their own risks--burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR, ) on the drug in the capsule. The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have developed polymers and other materials that begin to break down when they absorb either ultraviolet (UV, ) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds absorb NIR well and go through chemical changes. That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer. So Almutairi and her colleagues reported creating a new material for capsules that's even better.This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound called Bhc. When the... Question: Which word can be used to complete the following process of changes? Yes or no, is the answer "exposed"?
Ans: No

Ques: Article: We can achieve knowledge either actively or passively . We achieve it actively by direct experience, by testing and proving an idea, or by reasoning. We achieve knowledge passively by being told by someone else. Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive. Conditioned as we are to passive learning, it's not surprising that we depend on _ in our everyday communication with friends and co-workers* Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told even when it is little more than hearsay and rumor . Did you ever play the game Rumor? It begins when one person writes down a message but doesn't show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn, whispers it to still another, and so on, through all the people playing the game. The last person writes down the message word for word as he or she hears it. Then the two written statements are compared Typically, the original message has changed. That's what happens in daily life. The simple fact that people repeat a story in their own words changes the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative touch to a story, trying to improve on it, stamping it with their own personal style. Yet those who hear it think they know. This process is also found among scholars and authors:A statement of opinion by one writer may be re-stated as fact by another, who may in turn be quoted by yet another; and this process may continue, unless it occurs to someone to question the facts on which the original writer based his opinion or to challenge the interpretation he placed upon those facts. Question: According to the passage, passive learning may occur in _ . Yes or no, is the answer "visiting an exhibition"?
Ans:
No
