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? Yes or no, is the answer "It is a kind of polar bear."?
Yes

Article: Recently, another study has been carried out about who is the greatest American president. Sixty-five presidential historians took part in it and they judged the past forty-two American leaders based on ten qualities of leadership, which include public persuasion, crisis leadership, the management of economy, moral leadership and international relations. The historians also looked at administrative ability, relations with Congress, goal setting and pursuit of equal justice for all. Finally, the experts considered performance based on the historical period in which the president lived. The historians chose Abraham Lincoln as America's greatest president. He had also been named best president in a similar study in 2000. Abraham Lincoln was the only president in American history to lead the nation during the Civil War in the 1860s. He united the nation at last. And he took the first steps that destroyed the institution of slavery in America. Edna Medford is a professor of history at Howard University in Washington, D.C. She was an adviser on this study and the earlier one. She says Abraham Lincoln is seen to represent the values that the nation most honors like truthfulness, moderation and respect for human rights. The historians named America's first president, George Washington, as second on the list of greatest presidents. Franklin D. Roosevelt, Theodore Roosevelt and Harry Truman are next in that order. John F. Kennedy, the country's first Roman Catholic president, is sixth on the list. Like Abraham Lincoln, John F. Kennedy was murdered while in office. Among recent presidents, Ronald Reagan was named the tenth best president. Bill Clinton was rated fifteenth. And the historians rated former president George W. Bush as number thirty-six. His father, George H.W. Bush, did much better. He was rated as number eighteen. Question: Which of the following presidents did worst when he was in power according to the recent study? Yes or no, is the answer "George W. Bush"?
No

Article: We all know what it is like to be unable to turn your head because of a cold in the muscles of your neck, or because an unexpected twist has made your neck ache. The slightest move makes you jump with pain. Nothing could be worse than a pain in the neck. That is why we use the phrase to describe some people who give you the same feeling. We have all met such people. One is the man who always seems to be clapping his hands--often at the wrong time--during a performance in the theater. He keeps you from hearing the actors. Even worse are those who can never arrive before the curtain goes up and the play begins. They come hurrying down to your row of seats. You are comfortably settled down, with your hat and heavy coat in your lap. You must stand up to let them pass. You are proud of yourself-control after they have settled into their seats...Well, what now...God, one of them is up again. He forgot to go to the men's room, and once more you have to stand up, hanging on to your hat and coat to let him pass. Now, that is " _ ". Another, well--known to us all, is the person sitting behind you in the movies. His mouth is full of popcorn ; he is chewing loudly, or talking between bites to friends next to him. None of them remain still. Up and down, back and forth, they go--for another bag of popcorn, or something to drink. Then, there is the man sitting next to you at lunch, smoking. He wants you to enjoy it too, and blows smoke across your food into your mouth. We must not forget the man who comes into a bus or subway and sits down next to you, just as close as you will let him. You are reading the newspaper and he gets closer so that he can read the paper with you. He may even turn the paper to the next page before you are ready for it. We also call such a person a " _ , always getting close to where it does not belong, like neighbors who watch all your visitors. They enjoy learning about your personal business. People have a strong dislike for "rubber necks". They hate being watched secretly. Question: According to the passage, how do you feel when late comers walk back and forth in front of you in a cinema? Yes or no, is the answer "disturbed."?
Yes
