Read the passage and choose one correct answer for each question.

Between the Revolutionary period and the World War I, the United States post

office was set out to improve transportation of the post office mails. From those early

days to the present, the post office has helped develop and subsidize every new mode

transportation in the United States. Transportation has been the most important

element in mail delivery. Even when the general public had still suspected of the

security of a new means of transportation, the post office experimented with

inventions that offered potential for moving the mail faster, occasionally suffering

embarrassment, ridicule, or even abuse in the process.

As mail delivery evolved from foot to horseback, stagecoach, steamboat,

railroad, automobile, and airplane, with intermediate and overlapping use of balloons,

and helicopters, post office mail contracts ensured the income necessary to build the

great highways, rail lines, and airways that eventually spanned the continent.

By the turn of the 19

^th

century, the U.S. Post Office had purchased a number of

stagecoaches for operation on the nation’s better post roads – a post road being any

road on which the mail travels – and continued to encourage new designs to improve

passenger comfort and carry mail safely.
