Read the passage and choose the best answer for each of the following questions. Today, over six billion people live on planet. This means that there are very few places on Earth with no people. One place that has very few people is at the bottom of the Earth. In Antarctica, you will not live there all year round. First, Antarctica is the coldest place on Earth. For example, it can be minus 130 degrees in the winter. Human cannot live in this kind of environment. Because it is so cold, very few plants and animals live there. This means there are no farms and no places to find wild plants and animals to eat. In order for people to live in Antarctica food must be sent there on boats, and this is expensive. Another problem is that Antarctica can be dangerous. Many people think it is safe to travel to Antarctica in the summer months when it is warmer. However, Antarctica is mostly ice, so when it is summer, the ice melts. When the ice melts, it can break, so people cannot travel around Antarctica during the summer. If the ice breaks, they could fall into the water and die. Antarctica is a tough place to live. 1. What is the text about? A. Very few places on earth without people. B.
