49.Vegans try to live, as much as possible, in a way that avoids exploiting and being cruel to animals.“his means following a plant-based diet. Vegans do not eat animals or animal-based products like meat, fish, seafood, eggs, honey and dairy products such as cheese. For many vegans, living a committed vegan lifestyle means not wearing clothes made from animal skins and avoiding any products which have been tested on animals.Vegans argue that suffering is caused in the production of these foods. For example, they say that, on some dairy farms, male calves(小牛)are killed because they are too expensive to keep, and cows are killed when they get older and produce less milk. As for honey, vegans say that bees make honey for bee, not for humans, and that bees’health can suffer when humans take the honey from them. Vegans be lieve that the products they use and consume should be free from not just cruelty but any exploitation of animals.The main reason for going vegan is probably that they believe animals and all other sentient(有感知能力的)beings should have the right to life and freedom. However, there are other reasons. Vegans argue that the production of meat and other animal products is very bad for the environment. They point out that a huge quantity of water is needed to grow grain to feed animals in the meat industry. The enormous amount of grain which the meat industry needs often leads to forests being cut down and habitats(栖息地)being lost. In contrast, much lower quantities of grain and water are needed to sustain a vegan diet. In addition, many vegans say that all the nutritious elements our bodies need are contained in a carefully planned vegan diet and that this type of diet helps prevent some diseases.Which of the following could be found in a vegan’s diet?

42.In 2011, a dog owner named Robert uploaded a video titled“Guilty!” to YouTube. He had come home finding his two dogs near an empty bag of cat treats. The first dog behaved calmly. But the second dog, Denver, sat shaking in a corner, her eyes looking down, which made Robert believe it was she who had done it. Seeing her “apparent admission of guilt,” he yelled at her, “You did this!” Denver beat her tail nervously. “You know the routine. In the kennel(狗窝)!” Following the command, the dog shut herself in.The video quickly gathered a flood of comments. Since then, “dog shaming” has become popularOn the internet, as owners around the world posted beside notes shots of their trembling pets in which the dogs seemed to admit bad behavior. For instance, “I ate an extra large pizza,” admits a chocolate Lab. Human enthusiasm for guilty dogs seemed growing.But according to a researcher at Barnard College, what we consider to be a dog’s guilty look is no sign of guilt at all. In a 2009 study, the researcher had owners forbid their dogs from eating an attractive treat, and then asked the owners to leave the room. While each owner was gone, the researcher either removed the treat or fed it to the dog. When the owners returned, they were told-regardless of the truth-that their dogs either had or had not eaten it. If owners thought their dogs had done something wrong, blames followed, and guilty looks quickly emerged. Yet dogs who hadn’t eaten the treat were more likely to appear guilty than dogs who had-so long as their owners scolded them. Far from signaling regret, one group of researchers wrote in a 2012 paper, the guilty look of dogs is very likely a means to show obedience(顺从)to their owners.What does “a chocolate Lab” in Paragraph 2 refer to?
