Question

[Lê Quỳnh Anh]

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.

           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 indicates that it is expected doctors will be able to ________.

A. place more than one chip in a single person

B. place one large chip in a person to control multiple problems

C. place a chip directly inside a cell

D. place a chip inside a strand of hair

Answer 1

[Dương Hoàn Anh]

Đáp án A.

Key words: indicates, expected, doctors, be able to

Clue: “They believe that they will be able to implant multiple chips into a person”: Họ tin rằng có thể cấy nhiều chip vào một người.

Dựa vào clue ta chọn được đáp án đúng là A. place more than one chip in a single person: đặt nhiều hơn một con chip vào một cơ thể người

Các đáp án còn lại không đúng:

B. place one large chip in a person to control multiple problems: đặt một con chip lớn vào một người để kiểm soát nhiều vấn để một lúc.

C. place a chip directly inside a cell: đặt một con chip trực tiếp vào trong một tế bào.

D. place a chip inside a strand of hair: đặt một con chip vào trong một sợi tóc.
