They were free in their summer holiday. So they came to a village by a large lake. They liked fishing very much. Then the next day after they got there, they got to a boat and went fishing in the lake. They boated farther and farther. They came to an out-of-way place. They were very happy because there were a lot of fish. When it was time for them to go home, Bruce said to his friends: "We'd better make a mark here so that we will easily find the place tomorrow." "You're right." Bruno said happily ."Let me do that." "How foolish," said Bruce. "If it rains tonight, the rain water will wash the line off, and how can we find the mark tomorrow. You must cut a line with your knife." Dick came up to them and said angrily. " Neither of you is clever. How can we find the place if we have another boat tomorrow? We should not go back tonight." Question: They should make a mark _ Answer:
OPTIONS:
- thicker and color it red

input with options: Read the following article and answer the question. Article: You are probably familiar with the saying:An apple a day keeps the doctor away. A recent research carried out by the Chinese University of Hong Kong may change the saying: An apple a day may keep aging away. The research chose fruit flies , as they share many genes with humans. The fruit flies were either fed normally or had an apple extract added to their diet. It turned out that those fruit flies that were given apple extract lived about 55 days--five days longer than the flies that were normally fed. The research group also found it easier for the flies to walk,climb and move about as they aged. According to the result, the researchers believed that the antioxidants in the apple extract helped clean up dangerous chemicals that cause illnesses,as well as aging. In another study,researchers examined diets of thousands of women. They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke. The apples' genetic code was discovered recently. It allows scientists to develop nicer and healthier fruits. Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer. Apples that kill the desire to eat could also be produced, with the first"extra-healthy''apples on supermarket shelves within just four or five years. The team that keeps studying apple DNA includes 100 scientists from five countries. Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant,which would finally become today's apple tree, experienced a great genetic change. The number of many of its genes doubled. The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches,strawberries and other related fruits. Question: What can we infer from the passage? Answer:
OPTIONS:
- Eating apples may bring us more advantages than we might believe before.
- People who have the habit of eating apples don't need to see a doctor.
- Apples that kill the desire to eat are already available in supermarkets now.
- People will eat apples instead of peaches and strawberries from now on.
output: Eating apples may bring us more advantages than we might believe before.
