Input: Consider Input: Article: Glynis Davis: I first piled on the pounds when I was in the family way and I couldn't lose them afterwards. Then I joined a slimming club. My target was 140 pounds and I lost 30 pounds in six months. I felt great and people kept saying how good I looked. But Christmas came and I started to slip back into my old eating habits. I told myself I'd lose the weight at slimming classes in the new year... but it didn't happen. Instead of losing the pounds, I put them on. I'd lost willpower and tried to believe that the old bag of fish and chips didn't make any difference -- but the _ don't lie. Roz Juma: To be honest, I never weigh myself any more. I've learnt to be happy with myself. It seemed to me that I would feel sorry about every spoonful of tasty food that passed my lips. My idea is simple. You shouldn't be too much thinking about food and dieting. Instead, you should get on with life and stop dreaming of a super thin body. This is obviously the size I'm meant to be and, most of all, I'm happy with it. Lesley Codwin: I was very happy at winning Young Slimmer of the year. I'd look in the mirror unable to believe this slim lady was me! That might have been my problem -- perhaps from then on I didn't pay any attention to myself. Winning a national competition makes everything worse, though. Because you feel the eyes of the world are fixed upon you. I feel a complete failure because I've put on weight again. Ros Langfod: Before moving in with my husband Gavin, I'd always been about 110 pounds, but the pleasant housework went straight to my waist and I put on 15 pounds in a year. Every so often I try to go on a diet... I'm really good in a few days, then end up having the children's leftovers or eating happily chocolate -- my weakness. I'd like to be slim, but right now my duty is the children and home. I might take more exercise when my kids are older.

Input: Consider Input: 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.

Options: (A) forms very slowly (B) is a mixture of stones, pebbles and sand (C) makes up the layers of the earth (D) is becoming smaller and smaller

Output: Yes

Input: Consider Input: Article: The Lunar New Year, which starts in late January this year, is the most important festival for Chinese people as most of them drop any business at hand to go back to their hometown to see their families. It is a tradition that has been cherished since ancient times, but as social mobility increases in modern times, the road to family reunions has become very uneasy. It is not the higher travel costs, nor the expected big spending on gifts and other festival items, but the train ticket that has driven many travelers mad. I've heard some colleagues complain that they have tried every means to secure a train ticket, only to find it a mission impossible. Some of them have turned to the latest software to aid online booking; others have sought help from friends to increase the possibility of successful booking. No doubt chunyun, the Spring Festival travel season, is the largest-scale annual human migration in the world. Last year, 220 million passengers traveled by train during the Spring Festival season, which usually lasts 40 days. It is a huge jump from 10 years ago, when the number was 128 million. With the big sudden increase in demand, the railway company has increased investment in railway construction; still, it cannot bridge the supply gap, leading to fierce public complaints and criticism. Admittedly, it is almost impossible for the railway company to suddenly improve its capacity to meet the explosive demand during the Spring Festival holiday. Moreover, any temporary increase in capacity would become unnecessary after the holiday and mean great commercial losses during the off season. What the company can reasonably do is gradually improve its capacity while focusing on better distribution of its existing resources during the special peak season. At any rate, however, the problem cannot be solved overnight.
Question: Compared with ten years ago, the percentage of passengers last year increased by _ .
Options: (A) 40% (B) 58% (C) 71% (D) 83%
Asnwer: C
Output: Yes
