问题     It will be made in a similar way to brewing beer. We are not talking about a new kind of drink, however, but describing a new industry aiming to grow meat in the lab. This new food is known as clean meat, cultured meat or cultivated meat.
    Demand for meat has never been higher, but the way we produce it today is unsustainable. So scientists around the world are learning to grow meat and seafood in their labs without the need for farms or livestock. They have had considerable success—the world’s first lab-grown beef burger was cooked and tasted in London in 2013, though at a price of around $250,000, but costs have dropped since then. The challenge now is to turn these lab-based successes into food that can be sold on supermarket shelves at reasonable prices.
    This revolution is desperately needed. The world’s population is growing, with another 2 billion expected by 2050. Demand for meat is expected to grow by 70 percent, significantly increasing the pressure on limited resources such as land and water. This in turn will drive climate change. Today, livestock farming is responsible for 15 percent of global greenhouse gas emissions and is a key cause of deforestation. If meat could be grown in the lab instead of on farms, it could create an alternative to traditionally-produced meat and help reduce the environmental footprint for meat production.
    Cultured meat is produced using some of the same technologies biologists have used for decades to grow animal cells. First, muscle cells are taken from live animals, from which stem cells are isolated and then cultured in the lab. The next stage is more difficult, however. The cultured cells must then be grown and separated into a form of tissue comprising of muscle, fat and other cells that is suitable for food processing and consumption. Finally, this tissue will be processed and formed into products such as burger meat, sausages or shrimp meat.
    Currently, around 60 start-ups around the world are developing and improving the cultured meat process to make different meats and seafood. And they are all looking to scale up production while bringing down costs. So when will the fruits of this cellular agriculture reach the supermarket shelves? In the next few years we can expect a few launches of small-scale products in high-end restaurants. It will be a pretty expensive burger in a restaurant in Hong Kong or San Francisco, however, by 2030 you might see them on supermarket shelves at a decent price.
The author believes that cultured meat will________.
选项 A、become a promising industry
B、be produced on farms and sold on market shelves
C、have a more reasonable price than traditional meat
D、be firstly launched in Hong Kong or San Francisco
答案A
解析 推断题。作者在最后一段第一句提到“Currently，around 60 start-ups around the world are developing and improving the cultured meat process to make different meats and seafood”，以及第四句提到“In the next few years we call expect…”，表明作者对这个行业十分看好，故A项正确。B项是非混淆，全文一直反复强调人造肉是在实验室生产， 而不是在农场生产，故排除。C项主观臆断，该段最后一句结尾说you might see them on supermarket shelves at a decent price，也就是人造肉价格会变得合理，但并没有提到会比传统肉的价格更合理，故排除。D项以偏概全，原文最后一句说It will be a pretty expensive burger in a restaurant in Hong Kong or San Francisco，该句只是举例说明一个场景，并不代表着人造肉一定会首先在香港或旧金山推出，故也排除。
