[Q]: Article: Bears and humans often meet in National Parks. Although campers and hikers are warned not to feed the bears, many people ignore these warnings and feed the beasts anyway. When bears are used to people's food, problems soon arise. Bears like to eat a large variety of things, both meat and vegetable. Without human assistance, bears live nicely on roots, twigs, leaves of trees, insects and small animals. With people around, the bears' tastes quickly expand to include sandwiches, hot dogs, hamburgers, and anything else they can temp humans into giving up. Bears often develop clever strategies for getting people to let go their food supplies. More often than not, an unsuspecting hiker has taken off his or her pack for a rest only to have a bear charge out of the woods, grab the pack and quickly disappear into the underbrush with it. Hanging the pack on a tree branch won't help. Bears have been known to climb up, jump off, and catch the pack on the way down. One mother bear stretched up with her baby on her shoulders to reach a pack stored on a pole. Many bears threaten people into giving up their supplies. Although a bear is unlikely to attack a person and would probably run away if screamed at, few people are willing to do so. Most people drop the pack and run the other way. This, of course, delights the bear. In some places, the Park Service installed some metal barrels with lids to help campers keep their supplies safe from bears. Although the bears were unable to open these containers, the effort was less than successful. Most campers, unable to tell the metal drums from rubbish cans, never used them for the intended purpose.
Answer: can cause problems
[A]: Feeding bears on people's food_.

[Q]: Article: After their 20-year-old son hanged himself during his winter break from the University of Arizona five years ago, Donna and Phil Satow wondered what signs they have overlooked, and started asking other students for answers. What grew from this soul searching was Ulifeline (www. Ulifeline. org), a Web site where students can get answers to questions about depression by logging on through their universities. The site has been adopted as a resource by over 120 colleges, which can customize it with local information, and over 1.3 million students have logged on with their college ID's. "It is a very solid Web site that raises awareness of suicide, de-stigmatizes mental illness and encourages people to seek the help they need,"said Paul Grayson, the director of counseling services at New York University, which started using the service nearly a year ago. The main component of the Web site is the Self-screening program developed by Duke University Medical Center that tests students to determine whether they are at risk for depression, suicide and disorders like anorexia and drug dependences. Besides helping students, the services compiles anonymous student date, offering administrators an important window onto the mental health of its campus. The site provides university users with links to local mental health services, a catalog of information on prescription drugs and side effects, and access to Go Ask Alice, a vast archive developed by Columbia University with hundreds of responses to anonymously posted inquires from college students worldwide. For students concerned about their friends, there is a section that describes warning signs for suicidal behavior and depression. Yet it is hard to determine how effective the service is. The anonymity of the online service can even play out as a negative. "There is no substitute for personal interaction ," said Dr. Lanny Berman, executive director of the American Association of Suicidology, based in Washington. _ "The purpose is to find out if there are signs of depression and then direct people to the right places," said Ron Gibori, executive director of Ulifeline. Mrs. Satow, who is still involved with Ulifeline, called it "a knowledge base" that might have prevented the death of her son, Jed. "If Jed's friends had known the signs of depression, they might have seen something," she said.
Answer: give their students various help they may need
[A]: One reason that many colleges adopt the website is to _

[Q]: Article: Rice plants normally grow well in still water. But most will die if they are completely underwater for more than four days. Now, researchers have identified a gene that helps rice survive longer underwater. They say the discovery will lead to new kinds of rice plants that can survive flooding, and therefore reach their final aim, ensuring more dependable food supplies. Tests are now being done in prefix = st1 /Laos,BangladeshandIndia. The researchers say experimental rice plants with the gene have survived underwater as long as two weeks. When flooding happens, most kinds of rice plants cannot get enough oxygen, carbon dioxide or sunlight. But the scientists say crop loss depends on several conditions. These include soil conditions and plant age. Others include the amount of time the plant is underwater and the amount of fertilizer used on the crop. On a genetic map of rice, the scientists became interested in a group of three genes. They experimented with one of them, a gene known as Sub-One-A. They found that when this gene becomes very active, it improves the ability of rice to survive longer when rice is covered by water. They believe it succeeds because it affects the reaction to hormones . _ control the ability of a flooded plant to survive. Placing the gene into rice plants that are especially good for conditions inIndia, researchers say the genetically engineered plants not only survived but also produced good crops. The researchers are now trying to identify all the genes governed by the Sub-One-A gene. Being able to leave water on rice plants for an additional week might also help farmers prevent the growth of weeds. Less weed growth around their crops would mean less need for herbicide chemicals.
Answer: the amount of water the plant stands in
[A]:
Crop loss depends on all the following conditions EXCEPT _ .
