问题     Allelomimetic behavior may be defined as behavior in which two or more individual animals do the same thing, with some degree of mutual simulation and coordination. It can only involve in species with sense organs that are well enough developed so that continuous sensory contact can be maintained. It is found primarily in vertebrate, in those species that are diurnal, and usually in those that spend much of their lives in the air, in open water or on open plains.
    In birds, allelomimetic behavior is the rule rather than the exception, though it may occasionally be limited to particular seasons of the year as it is in the redwing blackbird. Its principal function is that of providing safety from predators, partly because the flock can rely on many pairs of eyes to watch for enemies, and partly because if one bird reacts to danger, the whole flock is warned.
    Among mammals, allelomimetic behavior is very rare in rodents, which almost never move in flocks or herds. Even when they are artificially crowded together, they do not conform in their movements. On the other hand, such behavior is a major system among large hoofed mammals such as sheep.
    In the pack-hunting carnivores, allelomimetic behavior has another function that of cooperative hunting for large prey animals such as moose. Wolves also defend their dens as a group against larger predators, such as bears. Finally, allelomimetic behavior is highly developed among most primate groups, where it has the principal function of providing warning against predators, though combined defensive behavior is also seen in troops of baboons.
Which of the following groups of human beings would probably show the greatest amount of allelomimetic behavior?

选项 A、A group of students taking a test.
B、Tennis players competing in a tournament.
C、A patrol of soldiers scouting for the enemy.
D、Drivers waiting for a traffic light to change.

答案C

解析 有些动物包括人类在受到干扰或攻击时有一种自我保护意识和遗传模仿行为。根据文章内容,可以推断遗传模仿行为在动物中常用作自我保护。这样,我们就可进一步推测在人类中也类似。可看出,侦察兵在执行任务时,容易受到敌人的攻击,自我保护意识强,因而也最可能具有遗传模仿行为,所以C项最佳。
