Question: Read the article and select the best answer. Article: Scientist Says 'No' to Human Cloning "I've never met a human worth cloning," says cloning expert Mark Westhusin from his lab at Texas A&M University. "It's a stupid endeavor." That's an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and a cat. They just might succeed in cloning Missy soon -- or perhaps not for another five years. Westhusin's experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog's eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted(,) fetuses may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. "Cloning is incredibly inefficient, and also dangerous," he says. Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin's phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. "A lot of people want to clone pets, especially if the price is right," says Westhusin. Cost is no obstacle for Missy's mysterious billionaire owner; he's put up $3.7 million so far to fund A&M's research. Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy's fine qualities after she does die. The prototype(;)is, by all accounts, athletic, good-natured and supersmart. Missy's master does not expect an exact copy of her. He knows her clone may not have her temperament(, ). In a statement of purpose, Missy's owner and the A&M team say they are "both looking forward to studying the ways that her clones differ from Missy." Besides cloning a great dog, the project may contribute insight into the old question of nature vs.... Question: We learn from the passage that animal clones are likely to have _ . Options: A: a bad temper B: defective(, )organs C: immune deficiency D: an abnormal shape
Answer: B

Question: Read the article and select the best answer. Article: BUNOL, Spain (AFP) -- Tens of thousands of people from around the world threw tons of ripe tomatoes at each other in an annual food fight that painted the eastern Spanish town of Bunol red. More than 40,000 people, including many visitors from Australia, Britain and the United States, took part in the food fight known as the "Tomatina", now in its 64th year, a spokeswoman for Bunol's town hall said. They were provided with over 100 tons of tomatoes by the town council for the battle which lasted about one hour and left participants covered in red. Many men were shirtless while others wore old clothes, hardhats, goggles or protective plastic sheets. Shopkeepers put up huge plastic covers on their store fronts or boarded them up to protect their properties from the sea of red mush . After the battle, governmental workers and local residents used "giant hoses" to clear the walls and streets of the tomato pulp in just half an hour while the participants headed to a nearby river where temporary showers were set up. The event cost the town of some l0, 000 residents 40,000 dollars, and Spanish media reported. The "Tomatina" is held each year in Bunol, located in a fertile region about 40 kilometers north of the coastal city of Valencia, Spain's third-largest city, on the last Wednesday in August. The origins of the event are unclear although it is thought to have its roots in a food fight between childhood friends in the mid-1940s in the city. It has grown in size as international press coverage brought more and more people to the festival. Question: To keep their stores safe, the shopkeepers _ . Options: A: kept their store fronts covered B: hung plastic sheets on the walls C: closed all the doors and windows D: stopped people throwing at them
Answer: A
