[不定项选择题]共用题干 第三篇

In the early days of the United States,postal charges were paid by the recipient and charges varied with the distance carried.In 1825,the United States Congress permitted local postmasters to give letters to mail carriers for home delivery,but these carriers received no government salary and their entire compensation depended on what they were paid by the recipients of individual letters.In 1847,the United States Post Office Department adopted the idea of a postage stamp,which of course simplified the payment for postal service but caused grumbling by those who did not like to prepay.
Besides,the stamp covered only delivery to the post office and did not include carrying it to a private address.In Philadelphia,for example,with a population of 150,000,people still had to go to the post office to get their mail.The confusion and congestion of individual citizens looking for their letters was itself enough to discourage use of the mail.It is no wonder that,during the years of these cumbersome arrangements,private letter-carrying and express businesses developed.Although their activities were only semi-legal,they thrived and actually advertised that between Boston and Philadelphia they were half-day speedier than the government mail.The government postal service lost volume to private competition and was not able to handle efficiently even the business it had. Finally,in 1863,Congress provided that the mail carriers who delivered the mail from the post offices to private addresses should receive a government salary,and that there should be no extra charge for that delivery.But this delivery service was at first confined to cities,and free home delivery became a sign of urbanization.In 1890,of the 75 million people in the United States,fewer than 20 million had mail delivered free to their doors.The rest,nearly three quarters of the population,still received no mail unless they went to their post office. Which of the following was a disadvantage of the postage stamp?
A.It had to be purchased by the sender in advance.
B.It increased the cost of mail delivery.
C.It was difficult to be posted on letters.
D.It was of poor quality.
