input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Scientists from England's Newcastle University have discovered that bacteria have the ability to detect smells, according to a study by the university on Sunday. The team of scientists, led by Dr. Reindert Nijland, discovered that bacteria can detect certain types of smell- producing chemicals, including ammonia that is produced by other bacteria. Once they sense the smells from other kinds of bacteria, the bacteria will gather together to form a colony and form a layer of slime in order to force the competitors out of their area. The response decreases as the distance between the two bacterial colonies increases. That slime, also known as biofilm, is one of the primary causes of infection on many medical implants . Biofilms also slow down ships and are believed to cost the marine industry millions of dollars annually. However, they can also be used to clean up spilled oil floating on the sea, as they grow strong on it. "This is the first evidence of a bacterial 'nose'able to detect potential competitors," Dr. Nijland said in the August 15 statement, which confirms that bacteria possess qualities similar to four of the five senses that humans enjoy (sight, hearing, touch, taste, and smell), the others being touch, taste, and sight. "The fact that bacteria formed slime when exposed to ammonia has important significance for understanding how biofilms are formed and how we might be able to use them to our advantage," he added. Their findings were published in Sunday's edition of biotechnology journal, and could change the way scientists look at how each of the senses developed over time. "It was thought for a long time that smell existed only in complex living creatures," Dr. Nijland said. "Now we see that bacteria are able to do the same, so the indication is that the ability may have developed even earlier." Options: A may cause oil to spill B can be used to benefit humans C are the major causes of infection D are more likely to be found on ships Answer: B can be used to benefit humans Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: The yearly Academy Awards ceremony was once a private affair. Now, because of television, it is very much a public affair. Hundreds of people gather in Hollywood to see the Oscars presented to outstanding actors, and others involved in the motion picture industry. Millions more watch on television. It all began on May 16, 1929, when 270 men and women sat down to dinner at the Hollywood Roosevelt Hotel. There was no secret about the winners. The names of the winners had been known for months. Janet Gaynor, for example, had won as Best Actress. Douglas Fairbanks presented her with the famous gold statue . The little statue was not then called Oscar. Like a new actor, Oscar was unknown. About six years later, it somehow got that renowned name. A number of explanations have been offered for its origin, but nobody knows the true story for certain. Nowadays the results of the Oscar voting are kept secret. Only two people know the winners before the names are announced at the ceremony. The counting of votes is not done by one group of people but by different groups. Nobody except two members of an accounting company sees the final results. The information is not kept in open files. Winners' names are placed in closed envelopes. The accountants each carry a complete set of envelopes to the ceremony. One set is simply a spare to be used in case something happens to the other one.
