C. READING 
 Read the passage carefully and choose the correct answer.
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 19th 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.
