Article: On Jan. 13th, 2009, the Peanut Corporation of prefix = st1 /Americaissued a recall for products it had made over the past six months, after five people had died and more than 400 had fallen ill with salmonella poisoning as a result of contamination. Two weeks later, the recall was extended to more than 400 consumer products made since Jan. 1, 2007, including Jenny Craig nutritional bars and Keebler Peanut Butter Sandwich Crackers, while the toll from the contamination had reached eight dead and more than 500 sickened in 43 states, half of them children. The company's factory in Blakely,Ga., which was the source of the contamination, supplied some of the largest food makers in the nation. The outbreak showed the complexities of the industrial food chain, and left consumers to figure out if some food in their cabinets had a danger. The recall of peanut products is the latest in a series of increasingly severe food contamination scares involving tomatoes, spinach, cantaloupes and other foods. TheGeorgiaplant, which is closed, packed peanut butter in bulk ranging from 5 to 1,700 pounds, much of which was shipped to institutions. Many school districts have pulled peanut butter from menus, with some substituting more commonly recognized supermarket brands. New York City school officials said they had not bought any peanut butter or products with ingredients that originated at theGeorgiaplant. An F.D.A. inspection team that visited the plant on Jan. 9 discovered that on 12 occasions in 2007 and 2008 tests conducted by the company found salmonella contamination in its products but that it shipped the contaminated products to customers after a retest found no contamination and did nothing to clean the plant. Question: The passage is mainly about _ . - the importance of food inspection in the US - the problems in the USfood industry - food poisoning in some schools - a recall for peanut products of a company
a recall for peanut products of a company

Read the following article and select the best answer. Article: If your dog looks pleased to see you - it is probably because it loves the particular way you smell. The odour of a familiar human apparently lingers like perfume in the animal's brain - where it triggers an instinctive emotional response, research published yesterday reveals. Our scent acts on a part of the canine brain associated with reward and the strongest reactions are produced by humans that pets know best, say scientists in America. Gregory Berns, of Emory University in Atlanta, said: 'While we might expect that dogs should be highly tuned to the smell of other dogs, it seems that the "reward response" is reserved for their humans. 'When humans smell the perfume or cologne of someone they love, they may have an immediate, emotional reaction that's not necessarily cognitive. 'Our experiment may be showing the same process in dogs. But since dogs are so much more olfactory than humans, their responses would likely be even more powerful than the ones we might have. 'It's one thing when you come home and your dog sees you and jumps on you and licks you and knows that good things are about to happen. 'In our experiment, however, the scent donors were not physically present. Why do animals avoid pylons? Because they emit terrifying flashes of light that are INVISIBLE to humans. Dolphins use sponges to protect their sensitive noses while foraging for food on the sea floor 'That means the canine brain responses were being triggered by something distant in space and time. It shows that dogs' brains have these mental representations of us that persist when we're not there.' The university's experiment - the first of its type - involved 12 dogs of various breeds who underwent brain scans while five different scents were placed in front of them. The scent samples came from the subject itself, a dog the subject had never met, a dog that lived in the subject's household, a human the dog had never met, and a human that lived in the subject's household. The familiar human scent samples were taken from someone else... Question: Why does your dog look pleased to see you ? - because your dog wants to play with you - because your dog is hungry - because your dog wants to attract your attention - because your dog loves the particular way you smell.
because your dog loves the particular way you smell.

I have seen manv parents,dive back into their children's lives at college admission time, trying to fill all of their wisdom and discipline into their children at the last moment. Parents may need to be sure as their children leave the nest that they reall} have taught them how to fly. Since it is impossible to assess the quality of what parents have done for their children at this point,the next best thing is the status of the colege to which the child is admitted. From the point of an anxious parent,an "Ivy l,eague college" child is proof of better child rearing than a "small college" child. I once sat with a talented,weak senior girl and her brilliant parents. She,they,and the school had to decide whether she should remam m school or go into a hospital. In light of her anorexia( ) ,the school recommended strongly that she not file her early application to Princeton. Upon hearing this,the girl looked at the adults in the room and said,"If I can't apply early to Princeton,l'll die. " Her parents were also eager to have her get into Princeton.
