[Q]: Write a multi-choice question for the following article, with the given choices and answer: 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. Options: A To identify the gene that helps rice survive underwater. B To increase the ability of rice to fight against floods. C To help farmers spend less time removing weeds. D To make sure of enough food supplies. Answer: D To make sure of enough food supplies. Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: It was when I was attending high school that I first read Asimov's stories. At the time, a few science fiction magazines began to introduce this author, and to translate a few pieces from his "Robot Series". Of Asimov's works, the one that left the deepest impression on me was Pebble in the Sky. This novel directly influenced my early science fiction writing. Asimov was one of the leading writers of western science fiction's Golden Age, so although his writing may not have a direct influence on writers of today, his underlying influence on many levels is undeniable -- the famous Three Laws of Robotics, and many classic writing techniques, for example. Asimov's novels are marked by a fully integrated logical system, and his stories are a pleasure to read. This is the reason his novels still attract readers today. Naturally, western science fiction has few people these days who follow Asimov's creative methods. But still the majority of Chinese science fiction readers would rather read the classic works of Asimov. Compared with the "Robot Series", Asimov's "Foundation Series" is a little less well-known in China. In fact, the "Foundation Series" creates an entire world, even grander than that of the "Robot Series"; this science fiction had a direct influence on later western science fiction, the most famous example being Star Wars. Options: A was not as successful as his "Robot Series" B is better known to readers than his "Robot Series" C was more logically organized than his "Robot Series" D was written better than his "Robot Series" in some ways Answer: D was written better than his "Robot Series" in some ways Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: After much thought,I came up with a brilliant plan.I worked out a way for Rich to meet my mother and win her over.In fact,I arranged it so my mother would want to cook a meal especially for him. Rich was not only not Chinese and he was a few years younger than I was.And unfortunately,he looked much younger with his curly red hair,smooth pale skin,and the splash of orange freckles across his nose.He was a bit on the short side,compactly built.In his dark business suits,he looked nice but easily forgettable,which was why I didn't notice him the first year we worked together at the firm.But my mother noticed everything. "So what do you think of Rich?"I finally asked,holding my breath. She tossed the eggplant in the hot oil,angry hissing sound."So many spots on his face,"she said. "They are freckles.Freckles are good luck."I said a bit too heatedly in trying to raise my voice above the noise of the kitchen. "Oh?"She said innocently. "Yes,the more spots the better." She considered this a moment and then smiled and spoke in Chinese:"When you were young,you got the chicken pox.So many spots,you had to stay home for ten days.So lucky,you thought." I couldn't save Rich in the kitchen.And I couldn't save him later at the dinner table. When I offered Rich a fork,he insisted on using the slippery ivory chopsticks.Halfway between his plate and his open mouth,a large chunk of redcooked eggplant fell on his brand new white shirt. And then he helped himself to big portions of the shrimp and snow peas,not realizing he should have taken only a polite spoonful. He declined the new greens,the tender and expensive leaves of bean plants.He thought he was being polite by refusing seconds,when he should have followed my father's example,who made a big show of taking small portions of seconds,thirds and even fourths,always saying he couldn't resist another bite and then groaning he was so full he thought he would burst. But the worst was when Rich criticized my mother's cooking and he didn't even know what he had done.As is the... Options: A "Ai!This dish not salty enough,no flavor,"she complained,after tasting a small bite. B Rich obviously had a different opinion on how the evening had gone C .Halfway between his plate and his open mouth,a large chunk of redcooked eggplant fell on his brand new white shirt. D "Linda,Tim",Rich said,"we'll see you again." Answer: C .Halfway between his plate and his open mouth,a large chunk of redcooked eggplant fell on his brand new white shirt. Question:
