Researchers believe that the insect(昆蟲) is better at managing congestion (擁擠) than humans. Ants are the most many type of animal on earth with brains that contain about 250,000 cells ---- the largest among insects.

Now an intelligence expert Dr. Dirk Helbing says understanding more about ants could help solve one of the headaches of modern life -- road congestion.

His team set up an "ant motorway" with two routes of different widths from the nest to some sugar syrup (糖漿). Soon the narrower（更窄的） route soon became crowded（擁擠的）. But when an ant returning along the crowded route to the nest met with another ant just starting out, the returning ant pushed the newcomer onto the other path. However, if the returning ant had enjoyed a trouble-free journey, it did not send the newcomer in a different direction.

The result was that just before one route became clogged , the ants had turned to another route and traffic jams never formed.

The researchers also created a computer model of more complex ant networks with routes of different lengths. The team found that even though ants being sent in another direction sometimes took a longer route, they still got to the food quickly and efficiently.

Dr. Helbing, of the Dresden University of Technology in Germany, said that while you cannot allow cars to meet with traffic coming in the opposite（相反的）direction as a form of traffic control, you could do the next best thing and allow them to communicate.

His plan is to force cars traveling in one direction to tell oncoming traffic what the conditions they are about to meet with-- so they can avoid that situation if necessary.

The first paragraph suggests that _______.

A. ants have a special way to manage congestion

B. ants are clever and good at dealing with the traffic jams because of developed brain

C. insects are similar to animals in dealing with the traffic jams because of developed brain

D. insects have more advantages than humans

The underlined word "clogged" can be replaced by _______ in the following four words.

A. cleaned         B. narrowed          C. crowded               D. shortened

If an ant returns along crowded route to the nest, how does the ant solve the traffic problem?

A. The ant will change the direction of its own.

B. The ant stopped the newcomer from moving ahead and forced the newcomer to wait there patiently.

C. The ant can't direct the newcomer.

D. The ant will push the newcomer to the other route, so traffic jams won't form.

What's the advice that Dr. Helbing gives us?

A. The cars cannot be allowed to communicate with traffic coming in the opposite direction.

B. The cars can communicate with traffic in the same direction.

C. The cars that travel in one direction can tell oncoming traffic about the traffic conditions.

D. We should build more routes of different lengths and widths.
