In 1895 Henson, Peary and Hugh Lee went out on another dog sledge journey. This time, they found Greenland's northernmost point. They now knew that the North Pole lay under the frozen Arctic Ocean. Peary had hoped to cross the ice. but the group ran out of food and returned to base camp. In the years that followed, Peary and Henson tried several times to reach the North Pole, but each time they failed. On one trip, Peary's feet froze, and he lost his toes . Peary and Henson planned last trip when Peary was 53 years old. They started across the sea ice from Ellesmere Island, which is located north of Canada. The temperature dropped as low as--51 degrees Celsius. The explores' cheeks froze , and they suffered snow blindness from the sun's glare.

Read the article and select the best answer. Article: Many of us believe that a person's mind becomes less active as he grows older. But this is not true, according to Dr Jarvik, professor of _ at the University of California. She has studied the mental functioning of aging persons for several years. For example, one of her studies concerns 136 pairs of twins , who were first examined when they were already 60 years old. As Dr Jarvik continued the study of the twins into their 70s and 80s, their minds did not generally decline as was expected. However, there was some decline in their psycho-motor speed. This means that it took them longer to finish mental tasks than it used to. But when speed was not a factor, they lost very little intellectual ability over the years. In general, Dr Jarvik's studies have shown that there is no decline in knowledge or reasoning ability. This is true not only with those in their 30s and 40s, but with those in their 60s and 70s as well. It is true that older people themselves often complain that their memory is not as good as it once was. However, much of what we call "loss of memory" is not that at all. There usually was incomplete learning in the first place. For example, the older person perhaps had trouble hearing, or poor vision, or was trying to learn the new thing at too fast a speed. In the cases where the older person's mind really seems to get worse, it is not necessarily a sign of decline due to old age. Often it is simply a sign of a sad emotional state. Question: This passage is mainly about _ . Options: A: what caused mental decline B: a new discovery about mental decline C: the difference between middle-aged and older persons D: how Dr Jarvik studied mental functioning of the twins
