input: OPTIONS:
- London stamps were not well printed
- London would not print them
- invitations to a big dance had to be posted quickly
- Mauritius had a very good printer Now, answer this question: 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: Why did Mauritius print some stamps too? Because _ . Answer:
