Đọc hiểu -TOEFL- Bài 36

Đọc đoạn văn sau và trả lời các câu hỏi:

   Researchers don't think there's any question that the discovery of
a gene which appears to be linked to many types of cancer is really
exciting and the best news for the public in a long time. The gene
is involved in a high percentage of human cancers and its discovery
5  might eventually lead to the development of a new anti-cancer treatment.

In normal cells this gene, named MTS1, acts as a brake during the
cell division process. But the researchers have found that the cell
is missing in about half of the tumor cells they studied, allowing
10 uncontrolled division of cells to take place, and the resulting spread
of the cancer.

This discovery could be exploited in two ways, either by supplying
the missing gene through gene therapy or by copying its function
15 in a drug. Of course, this is not the first gene to be found that
can suppress tumors; in fact it's the eleventh or twelfth. However,
because of its seemingly wider presence, or absence, the knowledge
of its existence could lead to a cure for some types of cancer.

1. What is the purpose of this passage?
(A) To show ways how cancer can be cured.
(B) To discuss about a new gene that has been found.
(C) To show how the new gene was found.
(D) To discuss anti-cancer treatment.
2. Why is the discovery good news for the public?
(A) It is involved in many cancers.
(B) It will cure cancer.
(C) It is the first of its kind.
(D) It may help researchers find a cure for cancer.
3. What does MTS1 do?
(A) It stops cells dividing.
(B) It kills tumors.
(C) It promotes cell division.
(D) It spreads with the cancer.
4. How might the discovery be used in the future?
(A) It can be used as a drug.
(B) It will be used as cure for cancer.
(C) It can be given to cancer patients.
(D) It can copy the function of a drug.
5. What does the author imply about the new discovery?
(A) It is exciting, but too involved.
(B) It is only one of eleven or twelve such genes.
(C) It may result in a cure.
(D) It only suppresses half of the tumors found.
