According to this passage, which factor influenced the Roman way of communication most?
In this high-tech digital world, it is very convenient for us to send messages. But in ancient times, people had to think hard to find ways to get the message sent.
Roman soldiers in some places built long rows of signal towers. When they had a message to send, the soldiers shouted it from tower to tower. If there were enough towers and enough soldiers with loud voices, important news could be sent quickly over distance.
In Africa, people learned to send messages by beating on a series of large drums. Each drum was kept within hearing distance of the next one. The drum beats were sent out in a special way that all the drummers understood. Though the messages were simple, they could be sent at great speed for hundreds of miles.
In the eighteenth century, a French engineer found a new way to send short messages. In this way, a person held a flag in each hand and the arms were moved to various positions representing different letters of the alphabet. It was like spelling out words with flags and arms.
Over a long period of time, people sent messages by all these different ways. However, not until the telephone was invented in America in the nineteenth century could people send speech sounds over a great distance in just a few seconds.
选项
A、People had to shout.
B、People could send complicated messages.
C、The messages could be sent out over a long distance within a time.
D、Both of the ways relied on messages in the form of sound.
答案
D
解析
罗马人靠士兵喊叫传递信息,非洲人靠打鼓传递信息,可知,他们都用声音传递信息,所以答案为D。
