Clone Farm Factory farming could soon enter a new era of mass production. Companies in the US are developing the technology needed to "clone" chickens on a massive scale. Once a chicken with desirable traits has been bred or genetically engineered, tens of thousands of eggs, which will hatch into identical copies, could roll off the production lines every hour. Billions of clones could be produced each year to supply chicken farms with birds that all grow at the same rate, have the same amount of meat and taste the same. This, at least, is the vision of the US’s National Institute of Science and Technology, which has given Origen Therapeutics of Burlingame, California, and Embrex of North Carolina $ 4.7 million A. Eggs are all genetically engineered. B. Thousands of eggs are produced every hour. C. Cloned chickens are bulk-produced with the same growth rate, weight and taste. D. Identical eggs can be hatched on the production lines. 更多"下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。请仔细阅读短"的相关试题: [单项选择] 下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。请仔细阅读短文并根据短文内容回答其后面的问题，从4个选项中选择1个最佳答案填。 {{B}}第一篇{{/B}}
