Question

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 following questions.

Scientists have developed a new bionic computer chip that can be mated with human cells to combat disease. The tiny device, smaller and thinner than a strand of hair, combines a healthy human cell with an electronic circuitry chip. Doctors can control the activity of the cell by controlling the chip with a computer.

It has long been established that cell members become permeable when exposed to electrical impulses. Researchers have conducted genetic research for years with a trial-and-error process of bombarding cells with electricity in an attempt to introduce foreign substances such as new drug treatments or genetic material. They were unable to apply a particular level of voltage for a particular purpose. With the new invention, the computer sends electrical impulses to the chip, which triggers the physicians to open a cell’s pores with control.

Researchers hope that eventually they will be able to develop more advanced chips whereby they can choose a particular voltage to activate particular tissues, whether they be muscle, bone, brain, or others. They believe that they will be able to implant multiple chips into a person to deal with one problem or more than one problem.

The author implies that scientists are excited about the new technology because _______

A. it is possible to kill cancer with a single jolt

B. It is less expensive than current techniques

C. It allows them to be able to shock cells for the first time

D. It is more precise than previous techniques

Answer 1

Đáp án D.

Key words: implies, scientists, excited, the new technology.

Clue: “Doctors can control the activity of the cell by controlling the chip with a computer”: Bác sĩ có thể điều khiển hoạt động của tế bào bằng việc điều khiển con chip trên máy tính.

Đọc bài ta sẽ thấy các nhà khoa học hứng thú với công nghệ mới bởi nó chính xác hơn những công nghệ trước đó. Cụ thể hơn, giờ đây bác sĩ có thể tự can thiệp và tham gia vào điều khiển hoạt động của tể bào. Nên đáp án chính xác nhất là D. It is more precise than previous techniques.

Các đáp án khác không đúng:

A. It is possible to kill cancer with a single jolt: Có thể giết chết ung thư bằng một cơn sốc.

B. It is less expensive than current techniques: Nó rẻ hơn các kỹ thuật hiện nay.

C. It allows them to be able to shock cells for the first time: Nó cho phép họ lần đầu tiên cỏ thể gây sốc tế bào.
