【正确答案】 B

【答案解析】[听力原文] Successful businesses adopt the philosophy that the customer is always right. McDonald's, famous for serving hamburgers, hasn't ignored that. It is opening, next year, its first totally vegetarian restaurant in India. About 40% of households in the country are vegetarian, according to the Food and Agriculture Organization of the UN, and the company, the world's second biggest food outlet, wants to beef up its operation. Hindus see cows as sacred and keep themselves from eating beef, while Muslims view pigs as unclean and avoid pork. Since it decided to enter the market, McDonald's has tried not to risk ending up with egg on its face. The chain's Indian menu has some meat-free dishes and some that include chicken. Vegetarianism has been around for centuries. According to the Vegetarian Society in Britain, the Greek philosopher Pythagoras favored the practice due to concerns about cruelty to animals. He also thought it could be a healthier lifestyle as it prevented men from being violent. Nowadays, the pressure on natural resources from rearing animals has been turning environmentally-conscious people into vegetarians. Some people are even stricter about eating animal products than vegetarians. They are known as vegans and they do not eat dairy products and eggs either. But some experts frown upon the idea of a meat-free diet. Dr. Elizabeth Weichselbaum, a nutritional scientist at the British Nutrition Foundation, says meat is an important source of a number of nutrients in our diet, including high quality protein, iron, zinc, vitamin D and some B vitamins. What can be learned about McDonald's? 短文提到It is opening, next year, its first totally vegetarian restaurant in India. 由此可知，为了迎合市场需求，麦当劳有在印度开素食餐厅的计划。因此答案为选项B。选项A和选项C是对原文的误解，排除；选项D属于过度推断，也排除。
