A monkey is sitting expectantly in a laboratory, wearing earphones that keep its head in an upright fixed position. Its hand rests at its waist near a telegraph key that it can feel but can not see. Soon a green light begins to blink and the monkey 【S1】______ the key to signal that it is ready. Then it hears two syllables coming through the earphones, realizes that the syllables are different, and correctly lifts the key.
This is not an amazing event in the field of research on primate behavior. Scientific studies on animal 【S2】______ have been conducted for many years. Chimpanzees, gorillas, and monkeys have all been taught to 【S3】______ messages from humans. What is new about this study is what the researcher noticed about the monkey’s use of its hands. Although either hand could have been used for pressing the key, everyone of the monkeys used its right hand. In other tasks, however, like grabbing food from a feeder or taking something that is offered to them, the monkeys seemed to have no 【S4】______ for one hand over the other.
It has 【S5】______ been assumed that only humans have the trait of 【S6】______ one hand. The right hemisphere of the brain controls the left arm and hand, and the left hemisphere of the brain controls the right arm and hand. 【S7】______ mental abilities such as speaking and understanding language are handled by the left side of the brain, so it is thought that this produces a dominance of right-handed humans. However, a 【S8】______ number of researchers are challenging this notion that nonhuman primates have no hand preferences. They argue that these traits can be 【S9】______ back to primates living tens of millions of years ago. Their contention is that primates use their right hands to perform precise manipulations where they can not clearly see what they are doing. And then why haven’t 【S10】______ noticed this before? It is difficult to set up experiments that require the kind of task where handedness is important.
A) researchers B) doctors C) growing D) generally
E) comprehend F) offer G) important H) preference
I) traced J) followed K) behavior L) favoring
M) presses N) shows O) strange
