Read the following passage and mark the letter A, B, C ,or D on your answer sheet to indicate the correct answer for each of the questions.

          Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes. These trails incorporate no directional information and may be followed by other ants in either direction.

          Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth.

         The vapor of the evaporating pheromone over the trail guides an ant along the way, and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space. In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail.

According to the passage, how are ants guided by trail pheromones?

A. They concentrate on the smell of food.

B. They follow an ant who is familiar with the trail

C. They avoid the vapor spaces by moving in a straight line.

D. They sense the vapor through their antennae.

. Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

                                                    

The volume of traffic in many cities in the world today continues to expand. This caused many problems, including serious air pollution, lengthy delays, and the greater risk of accidents. Clearly, something must be done, but it is difficult to persuade people to change habits and leaves their cars at home.

One possible approach is to make it more expensive for people to use their cars by increasing charges for parking and bringing in tougher fines for anyone who breaks the law. In addition, drivers could be required to pay for using particular routes at differ times of the day. This system, known as road pricing has already been introduced in a number of cities, using a special electronic card fixed to the windscreen of the car. Of course, the most important thing is to provide good public transport. However, to get people to give up the comfort of their cars, public transport must be felt to be reliable, convenient and comfortable, with fares kept at an acceptable level.
