Task 2 When people print a stamp, any error made on a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. More than one hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean, the mistake was made. In 1847 an order for stamps was sent to a London printer — Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a bail was planned at Mauritius’s Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the several hundred stamps that he printed. Today there are only twenty-six of these misprinted stamps left — fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blues’ rareness and age, collectors have paid as much as $16,800 for it. Stamp collectors have paid $16,800 for ______.

A. one Two Penny Blue
B. twelve Two Penny Blues
C. one One Penny Orange-Red
D. fourteen One Penny Orange-Reds
