Article: Another thing an astronaut has to learn about is eating in space.Food is weightless, just as men are. Food for space has to be packed in special ways.Some of it goes into tubes that a man can squeeze into his mouth.Bite-sized cookies are packed in plastic. There is a good reason for covering each bite.The plastic keeps pieces of food from traveling in the spaceship.On the earth very small pieces of food would simply fall to the floor.But gravity doesn't pull them to the floor when they are out of the plastic in a spaceship.They move here and there and can get into a man's eyes or into the spaceship's instruments. If any of the instruments is blocked, the astronauts may have trouble getting safely home. As astronauts travel on longer space trips, they must take time to sleep. An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat.But be careful he must put his hands under the belt when he goes to sleep.This is because he is really afraid that he might touch one of controls that isn't supposed to be touched until later. Question: Why would astronauts cover each bite of food in space? _ Yes or no, is the answer "Because weightless pieces of food might make trouble when they travel around."?
Yes

Article: In the dining room of my grandfather's house stood a massive grandfather clock. Meals in that dining room were a time for four generations to become one. The table was always spread with food containing love as the main ingredient . And that grandfather clock stood like an old family friend, watching over the laughter that was a part of our lives. As a child, the old clock fascinated me. I watched and listened to it during meals. Even more wonderful to me was my grandfather's ritual. He wound that clock with a special key carefully each day. That key was magic to me. It kept our family's magnificent clock ticking and chiming. I remember watching as my grandfather took the key from his pocket and opened the hidden door in the clock. He inserted the key and wound -- not too much, nor too little. He never let that clock wind down and stop. He showed us grandchildren how to open the door and let us each take turns winding the key. I remember the first time I did it I was so excited to be part of this family ritual. After my grandfather died, it was days after the funeral before I remembered the clock! "Mama! The clock! We've let it wind down." The tears flowed freely when I entered the dining room. The clock stood there quiet. It even seemed smaller without my grandfather's special touch. Some time later, my grandmother gave me the clock and the key. The old house was quiet. No laughter over the dinner table, no ticking or chiming of the clock -- all was still. I took the key in my shaking hand and opened the clock door. All of a sudden, I was a child again, watching my grandfather with his silver-white hair and blue eyes. He was there, winking at me, at the secret of the clock's magic, at the key that held so much power. I stood, lost in the moment for a long time. Then slowly and carefully I inserted the key and wound the clock. I sprang to life. Tick -- Tock, tick -- tock, life and chimes were breathed into the dining room, into the house and into my heart. In the movement of the hands of the... Question: The tears flowed freely when the writer entered the dining room because _ . Yes or no, is the answer "the writer missed Grandfather"?
Yes

Article: What is the difference between a college and a university? This is a good question for students who want to attend a college or a university in the United States. Colleges and universities have many things in common. Both provide a greater understanding of the world and its past. Both provide education in the arts and sciences. And both can help prepare young people to earn a living. Students who complete their undergraduate studies either at a four-year college or a university receive a bachelor's degree. One difference is that many colleges do not offer graduate studies. Universities are generally bigger, offer more programs and do more research. Modern universities developed from those of the Middle Ages in Europe. The word "university" comes from the Latin "universitas". This described a group of people organized for a common purpose. The word "college" comes from a Latin word with a similar meaning, "collegium". In England, colleges were formed to provide students with places to live in. Usually each group of students was studying the same thing. So college came to mean an area of study. But a college can also be a part of a university. The first American universities divided their studies into a number of areas and called each one a college. This is still true. Programs in higher learning may also be called schools. The University of Arizona in Tucson, for example, has 18 colleges and 10 schools. They include the colleges of pharmacy , education, engineering and law. They also include the schools of architecture, dance and public administration. College is also used as a general term for higher education. A news report might talk about "college students" even if they include students at universities. Or someone might ask, "Where do you go to college?" Today, most American colleges offer an area of study called liberal arts. These are subjects first developed and taught in ancient Greece. They include language, philosophy and mathematics. The purpose is to train a person's mind instead of teaching job skills. Question: The area of study called liberal arts is designed to _ . Yes or no, is the answer "help students achieve a stronger and clearer mind"?
No
