Some do it just for fun. Others compete. Climbing takes strength, control and good balance. Climbers have to pull themselves straight up the face of very high rocks or walls. So they have to be strong enough to carry their own weight. And climbers sometimes have to hold onto rocks by only their fingers or toes. There are several kinds of rock climbing. Traditional rock climbing is done outside. Climbers wear ropes and tie equipment to the rocks as they climb many hundreds of meters up. They also connect their ropes to the equipment. If a climber slips, a rope can stop him from falling. Sport climbing is similar. However, in it the protective equipment is placed in the rock all the time. There is also indoor climbing. Rock walls made of wood have places for the climber's hands and feet. Ice climbing is exactly as it sounds. People climb glaciers or frozen waterfalls instead of rocks. They use special equipment for the ice. And then there is bouldering-climbing rocks between three and seven meters high. It is quicker and stronger climbing. Many climbers like bouldering because they can use less equipment. Climbers often need only special shoes and chalk . All climbers use chalk to keep their hands dry. Most rocks have cracks and holes and parts that stick out. Climbers use these for foot-holds and handholds. Climbers use their legs to climb. They try not to pull themselves up with their hands or arms. Arms and hands are for position and balance. People almost always climb in groups of two or more. Climbing alone is very dangerous. Expert rock climbers say only the very best in the sport should do it. Question: Which of the following is TRUE about rock climbing? - Climbers use their hands or arms to climb. - Climbers use no special equipment for ice climbing. - Climbers do rock climbing in groups. - Climbers do rock climbing without ropes

Read the following article and select the best answer. Article: As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more. Lewis and his co-worker carried out their study by videotaping the families while they are having ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger,conversation gives way to the parents' efforts to control the loud noise they make. That can have an important effect on the children. "In general the more question-asking the parents do, the higher the children's IQ scores,"Lewis says. " And the more children there are, the less question-asking there is. " The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings . Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. " _ "says Lewis. When you see someone get up from the table and walk around during dinner,chances are for the middle child. "There is, however,one thing that stops all conversation and prevents anyone from having attention: "When the TV is on,"Lewis says, "dinner is a non-event ". Question: The writer's purpose in writing the text is to _ . - show the relationship between parents and children - teach parents ways to keep order at the dinner table - report on the findings of a study - give information about family problems
