input with options: Read the following article and answer the question. Article: In 1953, the New Zealander Edmund Hillary, then 33, joined a British Qomolangma expedition led by Colonel John Hunt. Tom Bourdillon and Charles Evans were the first team to attempt the summit . Despite a violent storm, they reached the South Summit -- at 28,700 feet (8,748 meters) -- by 1 p.m. on May 26. But both men knew they would run out of oxygen if they went on. They agreed to turn back. Two days later, Hillary and Norgay, set out from Camp IX at 25,900 feet to make the next attempt. At 27,900 feet they made a temporary camp on a six foot wide rock to spend the night. At 6:30 the next morning, cheered by clearing skies, the team moved out. Roped together, cutting steps with their ice axes, they inched up a steep, knife-edged ridge southeast of the summit. They reached the South Summit by 9:00 a.m. Farther up, they met a 40-foot icy rock face, which was later named the Hillary Step. "...looking up at the rock step at 29,000 feet, it really did look extremely difficult to overcome," said Hillary. But they found a narrow crack on the surface of the rock, just large enough to move inside on hands and knees, and managed to climb it by supporting feet against one side and backs against the other. Hillary said, "That was really the first moment during the whole of the expedition that I was confident that we were going to get to the top." The last few yards to the summit were relatively easy. "Then I realized that the ridge, instead of rising ahead, now dropped sharply away," Hillary said. "I looked upward to see a narrow ridge running up to a sharp point. ...and we stood on the summit." It was 11:30 a.m. on May 29, 1953. Question: What is the passage mainly about? Answer:
OPTIONS:
- The climbing history of Qomolangma.
- The life and achievements of Edmund Hillary.
- How Hillary and Norgay conquered Qomolangma.
- How the Hillary Step got its name.
output: How Hillary and Norgay conquered Qomolangma.

input with options: Read the following article and answer the question. Article: With a wildlife guide, I stepped on a journey to find one of the rarest creatures in the world ----the spirit bear, a walking contradiction--a white black bear. Neither albino nor polar bear, the spirit bear is a white variant of the North American black bear, and it's found almost exclusively here in the Great Bear Rainforest. At 25,000 square miles ---- one and a half times as big as Switzerland--the region is a spooky , wild, mysterious place: there are wolves here that fish. Deer that swim. Western red cedar trees that have stood a thousand years. And a black bear that is white. Scientists know how black bears are born white. They're just not sure why. The phenomenon, known as Kermodism, is caused by a recessive mutation at the MC1R gene, the same gene associated with red hair and fair skin in humans. To be born white, a bear must inherit the mutation from both parents. The parents themselves don't have to be white. They just need to carry the recessive mutation. So it's not uncommon for white bears to be born to black parents. White fur happens in only one of every 40 to 100 black bears on the British Columbia mainland coast, but the feature is especially distinct on certain islands in the Great Bear Rainforest. For example, on Princess Royal Island, one in ten black bears is white, and on Gribbell Island, directly north of Princess Royal, it's one in three. It's unclear how the feature arose. One theory was the "glacial bear" hypothesis that the spirit bear represented a remaining adaptation from the last great ice age, which ended here 11,000 years ago. At that time most of modern-day British Columbia was still icebound, and a white coat may have offered camouflage . But the "glacial bear" theory raised a question: Why didn't the white fur feature die out when the glaciers _ ? Researchers have recently proved that the spirit bear's white coat gives it an advantage when fishing. Although white and black bears tend to have the same success rate after dark, there is a difference during the... Question: Which of the following about the spirit bear is NOT true? Answer:
OPTIONS:
- It is a kind of polar bear.
- It is a white variant of the North American black bear.
- It is a walking contradiction.
- It's found mainly in the Great Bear Rainforest.
output:
It is a kind of polar bear.
