2022年3月13-19日GRE阅读题回忆及答案（三）来啦，来本文和新东方在线GRE一起来看看详细信息吧。

While captive orangutans learn to use tools, wild orangutans have not been observed doing so until recently when researchers witnessed orangutans near Suaq Balimbing in Sumatra using tools to extract insects from tree holes and seeds from the Neesia fruitWhat explains this population's tool use? It is doubtful that the Suaq orangutans are intrinsically smarter: captive orangutans have demonstrated that the species has the brain capacity to use tools. Another explanation is environmental. While previously studied orangutans mostly inhabited dry forests, the Suaq orangutans inhabit a lush swamp where insects flourish in tree holes and Neesia fruit is abundant. However, orangutans in other habitats where Neesia grows do harvest the seeds, but without tools they obtain fewer than do the Suaq orangutans.

1. The passage mentions "orangutans in other habitats where Neesia grows" primarily in orderto

A. explain why orangutans living in dry forests apparently do not use tools to obtain foods

B. propose an alternative to the environmental explanation for Suaqorangutans' tool use

C. demonstrate how environment may influence orangutan populations' brain capacity

D. contrast the food preferences of the Suaq orangutans with those of orangutans living in other habitats

E. Suggest that the Suaq orangutans' tool use cannot be explained merely by the availability of certain foods in their habitat

Consider each of the choices separately and select all that apply.

2. The passage suggests which of the following about orangutans that live mostly in dry forests?

A. They probably use some tools, though this tool use has not been observed by researchers

B. They dislike the foods that the orangutans living near Suaq Balimbing prefer.

C. They probably have the same capacity for tool use as have orangutans living near Suaq Balimbing.
