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 up to now, the point of applying electric impulse to cells was to _______.

A. open their walls to introduce medication

B. kill them

C. combine cells

D. stop growth

Answer 1

Đáp án A.

Key words: implies, applying electric impulse to cells.

Clue: “With the new invention, the computer sends electrical impulses to the chip, which triggers the physicians to open a cell’s pores with control”: Với phát minh mới này, máy tính có thể gửi lệnh xung điện tới con chip, khiến bác sĩ có thể mở lối vào tế bào với quyền kiểm soát của mình.

Như vậy chọn A. open their walls to introduce medication: để mở các thành tế bào để đưa thuốc vào. Các đáp án còn lại không đúng:

B. kill them: để giết chúng (tế bào)

C. combine cells: để trộn các tế bào

D. stop growth: đế dừng việc tăng trưởng
