Задание 2. Сделать задание к тексту.
Only humans have a spoken, symbolic language; scientists have long thought that nonhuman primates had much less sophisticated communication systems. True, but chimpanzees use gestures and many voice sounds in the wild, while other apes use sounds to communicate territorial information. Chimpanzees seem to have a natural talent for learning symbolic language under controlled conditions. A famous
chimpanzee named Washoe was trained to communicate with humans, using no less than 175 sign language gestures similar to those of the American Sign Language. After more than a year Washoe could associate particular signs with activities, such as eating and drinking. Another chimpanzee named Sarah was taught to read and write with plastic symbols and acquired a vocabulary of 130 different words, to the extent
that she obeyed sequences of written instructions given with the symbols. But such experiments in communication with primates are a far cry from the versatility and grace of human speech.



1. The passage states that the ability of chimpanzees to learn symbolic language in certain situations is due to
(A) their territoriality
(B) their use of gestures and voice sounds in the wild
(C) their natural talent
(D) their use of the American Sign Language





2. According to the passage, the chimpanzee Washoe
(A) was able to associate some signs with activities after a year
(B) used fewer than 175 signs to communicate
(C) was fluent in the American Sign Language
(D) could read and write


3. The passage states that Sarah's ability to read and write was judged by
(A) the size of her vocabulary
(B) her dexterity in using the plastic symbols
(C) her obedience to instructions given in the symbol language
(D) the number of symbol sequences that she could manipulate



4. According to the author, spoken, symbolic language is
A.  not a sophisticated communication system
B. only available to humans
C. shared by both
D. humans and chimpanzees
E. similar to the language used by chimpanzees
