Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The shocking collapse of one of the West Coast's biggest wild salmon runs has prompted even cash-trapped fishermen to call for an unprecedented shutdown of salmon fishing off the coasts of California and Oregon. The Sacramento River salmon run is usually one of the most productive on the Pacific Coast,providing the bulk of the salmon caught by sport and commercial trollers off California and Oregon. But only about 90,000 adult salmon returned to the Central Valley last fall--the second lowest number on record and well below the number needed to maintain a healthy fishery.That number is projected to fall to a record low of58.000 this year. The council,which regulates Pacific Coast fisheries,will choose between three management options:a total ban on salmon fishing off the coast of California and Oregon;extremely limited fishing in select areas;or catch-and-release fishing for scientific research. For consumers,it will be hard to find any Chinook,also known as king salmon.which are prized by trollers,seafood critics and upscale restaurants.There should still be abundant supplies of farm-raised salmon.but prices could be higher. Biologists and others are trying to figure out what caused the salmon collapse so they can make sure California's Chinook populations rebound. There are many potential factors,because wild salmon are born in streams and rivers, migrate to the ocean when they're juveniles and spend two to four years there before returning to spawn in the areas where they were born.In between they have to navigate the often dangerous waters of the Sacramento Delta and San Francisco Bay. The council has asked state and federal scientists to research possible causes, including water diversions,habitat destruction,dam operations,agricultural pollution,and ocean conditions.Many scientists point out that unusual weather patterns disrupted the marine food chain along the Pacific Coast in 2005,when thousands of seabirds washed up dead or starving because they couldn't find enough to eat. Researchers believe... Options: A abnormal weather patterns broke me marine food chain along the Pacific Coast B bad ocean condition prevented the salmon from returning to their birthplace C many salmons are eaten in the ocean before they are capable of returning D the dam operation may change the salmons'living environment in the river Answer: C many salmons are eaten in the ocean before they are capable of returning Question:

A: The possible causes of the salmon decrease mentioned do NOT include _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: America, has always had people of many different nationalities and languages. The 1990 census indicates that almost 14% of Americans speak a non-English language at home. Yet only 3% reported that they spoke English "not well" or "not at all ". That means that slightly more than one out of 10 Americans could be considered _ . Besides that, many high school and college students---and even some elementary school students---are required to take a foreign language. Actually, a growing number of Americans are coming to appreciate the benefits of using different languages. Ethnic enclaves have preserved the language and culture of American immigrants. Some local residents can function quite well in their native language, without having to bother learning English. Regions such as southern Florida and the Southwest have numerous Spanish-speaking neighborhoods. In fact, Spanish speakers---numbering over 17 million---form the largest non-English linguistic group in America. But Chinese, Vietnamese, Italian, Polish and many other ethnic group add to the linguistic flavor of America. Foreign languages are so commonly used in some ethnic neighborhoods that visitors might think they are in another country! Although some Americans welcome this linguistic and cultural diversity, others have begun to fear that the English language is being threatened. Since the 1980s, the "English Only " movement has sought to promote legislation which would establish English as the "official language" and restrict the use of non-English language. However, some groups, including TESOL, the organization for Teachers of English to Speakers of Other language, object to such "language restrictionism". But so far, 19 states have passed "English Only" legislation, and the topic is the focus of an ongoing debate. Whether or not English is the official language of the United States, it remains the "language of wider communication". Nearly everyone recognizes the need to develop the ability in using English in order to do well in America.... Options: A their native languages are commonly used in their neighborhoods B ethnic groups are not allowed to speak English C ethnic groups can do very well in their native languages D ethnic groups don't allow their natives to learn English Answer: A their native languages are commonly used in their neighborhoods Question:
