In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

Article: Why do men die earlier than women? The latest research makes it known that the reason could be that men's hearts go into rapid decline when they reach middle age. The largest study of the effects of ageing on the heart has found that women's _ may be linked to the fact that their hearts do not lose their pumping power with age. "We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age," said the head of the study, David Goldspink of Liverpool John Moores University in the UK. "Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men," said Goldspink. "This is part of the ageing process." What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's. "This gender( ) difference might just explain why women live longer than men," said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. "The team has yet to find why ageing takes a greater loss on the male heart," said Goldspink. The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

No

Article: Warm weather brought by El Nino has had mixed effects on animals in usually snowy places in North America, including New England, according to an Associated Press article. Some animals seem to benefit from having a chance to gather more food before winter, and from expending less energy in daily survival mode. Others, like snowshoe hares, are put at center stage in predators' view when they lack snow for disguising their white fur -- not a good thing for them, of course. Black bears, on the other hand, have been keeping busy gathering nuts and apples, when they would normally have settled into their winter homes by now. Vermont and Massachusetts officials have asked residents to wait till snow falls to take out their bird feeders for the sake of safety, the article said. "We suggest waiting for 6 or more inches of snow that lasts before taking out your bird feeders, especially if you have been visited in the past by bears or if there are sightings of bears in your neighborhood,"Forrest Hammond, Vermont Fish and Wildlife's bear biologist, said in the article."Due to lack of snow and frozen ground, birds are able to seek food in fields and forests for theirnatural foods." Snow amounts can also determine how comfortable bears are and how quickly they consume their accumulated fat during hibernation , noted Hammond in the article. This is because snow covers and traps them in their winter homes, and also hides them from predators.
Question: What may upset snowshoe hares because of El Nino?
Options: (A) Their being caught more easily. (B) Their failing to gather more food. (C) Their consuming more energy. (D) Their losing sight of their enemies.
Asnwer: A
Yes

Article: Half the world's population could face a shortage of food by 2100 due to climate change, a new report by US scientists warns. Rapid global warming is likely to reduce crop production in the tropics and subtropics , according to Professor David Battisti of the University of Washington. "The most extreme summers of the last century will become common," he says. "We must immediately create crops that can bear heat and drought if we are to adapt in time," he writes in Science journal. "The stresses on global food production from temperature alone are going to be huge," said Mr. Battisti. "And that doesn't take into account water supplies stressed by the higher temperatures." He worked with Professor Rosamond Naylor on Food Security and the Environment, to examine the influence of climate change on the world's food supplies. They predict there is a greater than 90% probability that by 2100, the average growing-season temperatures in the tropics and subtropics will be higher than any temperatures recorded there to date. "We are taking the worst of what we've seen historically and saying that in the future it is going to be a lot worse unless there is some kind of adaptation," said Professor Naylor. "This is a powerful reason for us to invest in adaptation, because it is clear that this is the direction we are going in terms of temperature and it will take decades to develop new food crop varieties that can better bear a warmer climate." "In the tropics, the higher temperatures could be expected to cut production of the primary food crops by 20-40%," the researchers said. Rising temperatures are also likely to reduce soil moisture , cutting production even further. Three billion people live in the tropics and subtropics now, and their number is expected nearly to double by the end of the century. "You are talking about hundreds of millions of additional people looking for food because they won't be able to find it where they find it now," said Professor Battisti. Crop failures would not be limited to the tropics, the scientists concluded.
Question: According to Professor David Battisti, what should be done to deal with crops reduction caused by global warming?
Options: (A) To develop new crops (B) To plant more crops. (C) To control population growth. (D) To improve farming technology.
Asnwer: A
Yes
