In the early clays 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 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 150000, people still had to go
to the post office to get their mail. The confusion
A. increased

Passage Three
In early 2004 eight tiny sensors were dropped from a plane near a military base in California. After hit ting the ground, the sensors—also known as smart dust sensors organized themselves into a network and quickly detected a fleet of military vehicles on the ground. They determined the direction, speed and size of a series of military vehicles traveling along the road and later transmitted the data to a computer at a nearby base camp.
Smart dust sensors are minicomputers—as small as a grain of rice in some cases—that can monitor and evaluate their physical environment and can relay the information via wireless, communication. They can monitor elements such as temperature, moisture, humidity, pressure, energy use, vibration, light, motion, radiation, gas, and chemicals. These devices will soon have many applications, such as use in emergency rescue.

A. giving troops their protective gear
B. organizing themselves into a computer network
C. detecting the movement of military vehicles nearby
D. operating in remote and dangerous War zones
