问题     In 2013, food critic and writer Hanni Ruetzler took a taste out of a dish costing more than $300,000 and remarked how it was "close" to tasting like real beef. The dish in question was not a plant-based meat alternative; it was in fact real beef—beef that was made in a lab \ This taste test was the first lab-grown beef dish, and it was created by Dr. Mark Post and his cellular agriculture research team in the Netherlands. Cellular agriculture encompasses the fascinating field of growing agricultural products, like meat and milk, from cell cultures in a laboratory setting. This innovative process eliminates the need to use livestock to obtain the same products and, consequently, cellular agriculture is being explored as an alternative to the present livestock agricultural system.
    As previously mentioned, cellular agriculture is the field of growing agricultural products directly from cell cultures in a laboratory instead of using livestock. At the moment, the primary research has revolved around growing meats (beef, pork, poultry) as well as animal products (milk and egg white) in cell cultures. Instead of raising, for example, a cow from birth for milk and meat, cellular agriculture presents an alternative way to get the exact same real product without all of the problems associated with raising livestock.
    In comparison to conventional livestock agriculture, meat produced via cellular agriculture would use approximately less than a tenth of the land and less than a tenth of the water as well as less than half of the energy use. This meat would also produce significantly less greenhouse gas emissions. The growing global demand for meat and animal products illustrate that most people are not prepared to change their eating habits and lifestyle from eating meat to plant-based alternatives and, consequently, instead of urging people to eat more plant-based diets, the next best option is to find a better way to produce meat, and that is exactly what cellular agriculture offers.
    It is also important to note that, by avoiding the use of actual livestock to make products, cellular agriculture would also impact animal welfare. Otherwise, as the global demand for meat increases, large factory farms would be put under more pressure to produce more animal products, and, consequently, it is likely that animal welfare conditions would worsen from their current state, including increased confinement and imperfect slaughter conditions, to meet the market demand.
    Besides, cellular agriculture meat would not be fed the large amounts of antibiotics that are given to animals in conventional livestock agriculture. In addition, most bacterial contaminations that cause food-borne illnesses, such as E. coli and salmonella, often occur through interaction with infected animal feces. By cutting out livestock in cellular agriculture, this problem can be solved.
    There are still many obstacles to overcome before cellular agricultural products become commercial, such as issues relating to scaling the production process and overcoming any regulatory hurdles. One of the most difficult obstacles to overcome, however, may be challenging any negative public perception of food that come from cell cultures in a laboratory instead of from animals. To overcome this, it will be important to inform the public on what cellular agriculture is and how this field provides a solution to an unsustainable livestock agricultural system. On top of that, it will be very important for all actors in this field to be transparent and clear about all of their scientific findings as well as all aspects of the manufacturing processes.
What is this passage mainly about?
选项 A、Potentials of cellular agriculture.
B、An overview of cellular agriculture.
C、People’s doubts about cellular agriculture.
D、A research concerning cellular agriculture.
答案B
解析 主旨题。纵观全文，文章介绍了细胞农业的定义、优势和面临的障碍，整体而言是对细胞农业的简单介绍，因此答案选[B]。其他选项都比较片面。
