input question: Write a multi-choice question for the following article: Article: Scientists in Israel have discovered a new way to test for water pollution by "listening" to what the plants growing in water have to say. By shining a laser beam on the tiny pieces of _ floating in the water,the researchers said they hear sound waves that tell them the type and amount of contamination in the water. "It is a red light,telling us that something is beginning to go wrong with the quality of water," said Zvy Dubinsky,an aquatic biologist at Israel's Bar Ilan University."Algae is the first thing to be affected by a change in water quality.""The secret," he said,"is to measure the rate of photosynthesis in the algae,meaning the plant's ability to transform light into energy." During photosynthesis,plants also release oxygen into the air. Dubinsky's technique is easy to perform because of the overabundance of algae in the planet's water.Most of the oxygen in the atmosphere comes from algae.A prototype tester that occupies about one square meter of a laboratory desktop,shoots a laser beam at water samples to stimulate photosynthesis in the algae.But not all of the laser's heat is used.Depending on the condition of the algae and the rate of photosynthesis,some of the heat is shot back into the water,creating sound waves,Dubinsky said.With a special underwater microphone,researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water. "Algae suffering from lead poisoning,like waste discharged from battery and paint manufacturing plants,will produce a different sound than those suffering from lack of iron or exposure to other toxins," said researcher Yulia Pinchasov.She said that testing algae photosynthesis can determine water quality more accurately and easily than laborintensive methods now used like chemical and radioactive carbon testing.???

input question: Write a multi-choice question for the following article: Article: The world's most famous awards, the Nobel Prizes, are given for achievements that benefit humankind. Ironically they are named for a 19thcentury scientist who invented powerful explosives that came to be used as weapons of war. Alfred Nobel, a Swedish-born chemist who died in 1896, was known by some as "The Mad Scientist," and by others as "The Merchant of Death." He was really pacifist, who at one time believed that his explosives could end warfare. Later, he realized that he was wrong. "High explosives will not stop men from war," he wrote. "Nobody will benefit from my inventions except manufacturers of war materials, some generals, and diplomats." Nobel was born in Sweden in 1833. His father was an architect and inventor who moved to Russia. With only one year formal schooling, Nobel became a chemist and inventor by the age of 16. He was also excellent in languages, speaking English, Russian, German, and French in addition to Swedish. He wrote poetry. His study of explosives began with manufacturing liquid nitroglycerin for use in mining and construction. But in 1864, the factory blew up, killing his youngest brother and four others. He then discovered that liquid nitroglycerin could be dried and handled safely to be a mixture, which can explode. He called the mixture dynamite, after the Greek word dynamis, meaning "power." He then perfected a more powerful form of dynamite that made him a multimillionaire. When he died, his fortune was about $9 million. Nobel never married, and he left his fortune to what has since become known as the Nobel Prizes. The money is invested and the interest is given out every year as prizes for the most important work in six fields: Physics, Chemistry, Physiology or Medicine, Literature, and Peace. Nobel Prize winners receive money, a gold medal, and a diploma. Prizes were first awarded in 1901, and the list of Nobel laureates contains many well-known names: Albert Einstein in Physics, Marie Curie in Chemistry, Toni Morrison and William Faulkner in Literature, Martin Luther...???
