Q: Read the following article and answer the question. Article: Don't worry, be happy and, according to new research, you will also be healthy. It is estimated that over the course of one year, Americans suffer 1 billion colds. But new research shows that all it may take to avoid this common affliction is a positive and upbeat attitude. People who are energetic, happy and relaxed are less likely to catch a cold than those who are depressed, nervous or angry, finds a new study published in the journal Psychosomatic Medicine. Healthy volunteers first underwent an emotional assessment in which they were asked to rate their tendency to experience positive and negative emotions--how often they felt pleased, relaxed, happy, or anxious, depressed and hostile. The subjects were next given a squirt up the nose of a rhinovirus, the nasty little germ that causes colds. Researchers then watched the volunteers to see who came down with a cold and waited to see how the unlucky ill manifested their cold symptoms. "We found that people who regularly experience positive emotions, when exposed to rhinovirus, are ly protected from developing illness," said Dr. Sheldon Cohen, lead author of the study and a psychology professor at Carnegie Mellon University." Increases in positive emotional styles were linked with decreases in the rate of clinical colds, but a negative emotional style had no effect on whether or not people got sick," Cohen said. So how can your emotions influence your health? In simple terms, when the brain is "happy" it sends messages to our organs that help keep the body healthy and sound." It's like a drug that is released by your state of mind and simply changing the state of mind can produce effects on the rest of the body through the nervous system and hormones," said Dr. Neil Shulman, associate professor of medicine at Emory University School of Medicine and author of Doc Hollywood. "Your chance of developing the common cold, pneumonia, or even cancer may very well be decreased by keeping your brain in a healthy state." In addition,... Question: The experiment states that _ Answer:

- positive people show a greater resistance to colds.
- negative people necessarily get sick more often.
- the alternative emotional styles have effect on whether or not people get sick
- positive people have stronger immune functions than negative ones

A: positive people show a greater resistance to colds.

input: OPTIONS:
- Most people are interested in Jiang Shan's art-piece, which brings about a feeling of warmth.
- Most visitors will kiss each other in front of the stainless steel mirror at the gate.
- All the decorations in the mall are aimed at encouraging lovers to express their love bravely.
- The 18-meter-high interactive tree-shaped light equipment will be on for each kiss. Now, answer this question: Read the following article and answer the question. Article: Shanghai Xintiandi Style Mall is filled with a festive mood, featuring large-scale equipment, knit works and various activities, under the theme "kiss". "Kissing is seldom taken as the theme of artworks because in oriental culture, people restrain themselves from expressing their emotions," says Jiang Shan, who is in charge of the exhibition. "Through the exhibition, we hope to encourage people to be confident and brave in expressing their love." Inside the mall, which covers a large area from Zizhong Lu (Road) to Fuxingnan Lu (Road), dozens of color1ful decorations, including balloons, lollipops and lip-shaped decorations are hung on the walls and from the ceiling. Among the decorations, a bright-color1ed wool artwork attracts most eyeballs and brings about a feeling of warmth. The designer, Gu Yeli, says the art piece, Kiss Forest, was inspired by US artist Andy Warhol's 1963 experimental film Kiss, which featured various couples kissing for three and a half minutes each. Gu also organizes a small workshop to teach knitting to children. Artist Wang Xuejun sets up a stainless-steel mirror at the mall's gate leading to Zizhong Lu. Visitors, including men, are invited to put on lipstick and kiss the mirror, thus kissing themselves. The Beast Floral Shop, a flower shop in Shanghai, contributes two walls of flowers that are made into the shape of a book, named Kiss Book. Artifacts of bees and butterflies are fixed among the blossoms, kissing the flowers. The work represents love and harmony in nature. Architect Ma Ke creates a Kiss Bridge with transparent acrylic boards and ceramic fishbowls. Bridges are often spots for dating lovers in traditional Chinese folk stories and the goldfish in the bowls are witnesses of the lovers' kisses. In the south plaza, an18-meter-high interactive tree-shaped light equipment encourages people to kiss. Each kiss turns a certain light on, reminding audiences of their sweet childhood memories of kisses. At the side of the tree is a counter, in which each kiss is counted... Question: What can we learn from the article? Answer:
A:
output: The 18-meter-high interactive tree-shaped light equipment will be on for each kiss.

Problem:OPTIONS:
- the dolphins might affect the existence of fishes in Haifa port
- he is curious about the dolphins
- he will do research on the dolphins
- he is uncertain about what will happen to the dolphins

Read the following article and answer the question. Article: Dozens of dolphins swam out of the polluted waters of Haifa Harbor on Tuesday.This was the first time that dolphins had visited this crowded Mediterranean port,and researchers were surprised and delighted by the unexpected event. Between 40 and 50 of the dolphins appeared in the busy port on Tuesday morning,obviously drawn by the fishrich waters of Haifa Harbor. However,the bay is also full of harmful chemicals. Aviad Sheinin,professor of Haifa University's Maritime Studies Department,said he didn't think the dolphins were harmed by the pollution,but he hoped that they would swim back to the sea soon. "It seems that they are quite relaxed. They don't seem to be stressed," he said. Haifa Harbor is lined by chemical companies that have been pouring poisonous waste into the water for decades. While pollution levels have dropped in recent years,the water is still considered a health hazard. "There are lots of fish in Haifa Harbor. Unfortunately we couldn't tell the dolphins that the fish are not healthy;and I don't know what the result will be," he told Israel Army Radio.Hundreds of Haifa residents gathered around Haifa Harbor to see the interesting sight,and researchers said this provided a rare chance to film and study the roughtoothed dolphins. In addition to the dozens of dolphins which swam into the port on Tuesday,a similar number stayed outside the breakwater .Later Tuesday the dolphins left the port but remained near the entrance and Israel's coast guard was patrolling the area to try to make sure the dolphins didn't reenter the poisonous waters. Relatively little is known about roughtoothed dolphins,which are usually found in deep and warm tropical waters. Question: Aviad Sheinin's words suggest that _ . Answer:
****
A:
he is uncertain about what will happen to the dolphins
