user: Question: Article: In 1990,22-year-old Christopher McCandless gave up his career plans,left behind everyone he knew,donated all his savings to charity,and went off on an adventure,hiking his way through America to Alaska. Of course,this is an unusual story most college graduates would not do so. However,studies show that in teenage years, people are more likely to try out new experiences.For example,instead of working his way up the same organization like his grandfather did,a 15-year-old may dream about becoming a travelleronly to find in his early 20s that this attraction of new places is fading and change is less attractive. The reason why people become less keen to change as they get older may be that people generally have similar life patterns and demands.Most people aim to find a job and a partner. As they get older,they may have young children and elderly family members to look after. These responsibilities cannot be achieved without some degree of steadiness,which means that new experiences and ideas may not have a place in the person's life.New experiences may bring excitement as well as insecurity,and so most people prefer to stay with the familiar. However,not every individual is the same. A child may want to play a different game every day and get fed up if nothing changes at the kindergarten.Another may play with the same children and toys on every visit. Young children who avoid new experiences will grow up to be more traditional than others. Psychologist argue that those who have more open personalities as children are more open than others might be when they are older and that young men have a greater interest in novelty than women,although as they age,this desire for new experiences fades more quickly than it does in women. Question: What does the author think is the key factor that prevents people trying out new experiences? Yes or no, is the answer "Responsibility"?
Answer: Yes

Question: Article: At first, the earth's surface layer   was made up of huge blocks of hard, solid rocks. Then slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebbles   and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil. There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks in the rock, which become bigger and finally the rock breaks up into smaller pieces. The moving water of streams and rivers also helps to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces. The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces. Question: How many factors are mentioned in helping break up rocks? Yes or no, is the answer "Four."?
Answer: No
