input with options: Read the following article and answer the question. Article: How can a small stamp be worth $16,800? Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on a two-penny stamp has made it worth a million and a half times its face value. Do you think it impossible? Well, it is true. And this is how it happened. The mistake was made more than a hundred years ago in the former British colony of M auritius , a small island in the Indian Ocean. In 1847 an order for stamps was sent to London. Mauritius was about to become the fourth country in the world to put out stamps. Before the order was filled and the stamps arrived from England, a big dance was planned by the commander-in-chief of all the armed forces on the island. The dance would be held in his house and letters of invitation would be sent to all the important people in Mauritius. Stamps were badly needed to post the letters. Therefore, an islander, who was a good printer, was told to copy the pattern of the stamps. He carelessly put the words "Post Office" instead of "Post Paid", two words seen on stamps at that time, on the several hundred that he printed. Today, there are only twenty-six of these misprinted stamps left--- fourteen One-penny Reds and twelve Two-penny Blues. Because there are so few Two-Penny Blues and because of their age, collectors have paid as much as $16,800 for one of them. Question: When a mistake is made in the printing of the stamp, the stamp _ . Answer:
OPTIONS:
- will be thrown away
- increases in value
- is not worth buying
- is worth no more than its face value
output: increases in value

About four-fifths of high school students in China have poor eyesight . And now more and more children in primary school need glasses, too. Two main reasons can cause poor eyesight: too much time spent indoors studying and too little time spent outdoors playing. Reading and writing for hours and hours, sometimes in poorly lighted rooms, causes eyesight to weaken. But students have to do this because there is so much pressure on them to succeed in school. They have less time to enjoy the sun. The sun, it turns out, is important in developing good eyesight. According to a study by Australian National University, Australian children and Chinese children have the same level of eyesight before they start school, but once they enter primary school, Chinese children only spend about an hour a day outside, while Australian children spend three to four hours each day in the sunshine. The result is that while about forty percent of Chinese primary school students need glasses, only three percent of Australian children do. And poor eyesight at a young age can have serious long term influence. As you get older, your eyesight can worsen. With all that in mind, don't you think it's time to give your eyes a break? Question: How many high school students have poor eyesight in China according to the reading? Answer:
A:
output: Four-fifths of them.
