Good morning, everyone. Today we're going to discuss the history of the postal service. In the 19th century, the introduction of the postage stamp revolutionized communication. Before that, the receiver usually paid for the letter, which was often expensive and led to many refusals. The first adhesive stamp, the Penny Black, was issued in Britain in 1840. It featured a portrait of Queen Victoria. Interestingly, this stamp was so successful that other countries quickly adopted similar systems. However, the initial design had a flaw: the black color made it difficult to see the cancellation mark. Therefore, it was soon replaced by the Penny Red in 1841.
❓ Why was the Penny Black stamp replaced by the Penny Red?
A. A. The black color showed the postmark too easily.
B. B. The red color was cheaper to produce.
C. C. The portrait of Queen Victoria was not clear.
D. D. The stamp was too large for envelopes.
✅ 正确答案
