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 from 38 to 42.

Insects’ lives are very short and they have many enemies, but they must survive long enough to breed and perpetuate their kind. The less insect-like they look, the better their chance of survival. To look "inedible" by imitating plants is a way frequently used by insects to survive. Mammals rarely imitate plants, but many fish and invertebrates do.

The stick caterpillar is well named. It is hardly distinguishable from a brown or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called "measuring worm" or "inchworm." It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind fed forward, when danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed.

Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection: they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long, when at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live.

Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the plants that they resemble.

Question 38. Đáp án C

Câu hỏi. Ý chính của đoạn văn là gì?

A. Sâu bướm sống trên cây

B. Thói quen kiếm mồi của côn trùng

C. Cách một số côn trùng ngụy trang giống thực vật để sinh tồn

D. Những loài côn trùng bị đe dọa tuyệt chủng

Đây là câu hỏi hỏi ý chính của văn bản. Trong đoạn 1 dòng 3, ta tìm thấy thông tin:

To look "inedible" by imitating plants is a way frequently used by insects to survive.

Tạm dịch. Để trông có vẻ không ăn được bằng cách giả mạo giống cây cối là cách thường được côn trùng sử dụng để tồn tại.

Ngoài ra khi đọc lướt toàn bộ vàn bản ta thấy văn bản không viết về một loại côn trùng cụ thể nào mà viết về nhiều loài khác nhau nhưng có đặc tính giống nhau đấy là ngụy trang để tránh kẻ thù. Như vậy đáp án C hợp lý hơn cả.
