Which of the following statements is NOT true?
A. The San Andreas fault is two miles deep.

Chọn đáp án B
Khẳng định nào sau đây là KHÔNG đúng?
A. Chỗ đứt gãy San Andreas là hai dặm sâu.
B. Các nhà khoa học ở Hoa Kỳ tìm thấy vết trượt trong chỗ đứt gãy vào những năm 1980.
C. Động đất xảy ra khoảng 22 năm một lần dọc theo đứt gãy San Andreas.
D. Sự trượt ở chỗ đứt gãy có thể dự đoán được khi chỗ đứt gãy sẽ đứt vỡ ra.
=> Theo thông tin trong đoạn văn như sau:
+ Đáp án A: “At first the event seemed random but scientists drilled deeper. By 2005 they reached the bottom of the fault, two miles down, and found something.” (Lúc đầu, sự kiện này có vẻ ngẫu nhiên nhưng các nhà khoa học đã khoan dò sâu hơn. Đến năm 2005 họ chạm đến đáy của chỗ đứt gãy, sâu xuống hai dặm, và tìm thấy một cái gì đó.)
+ Đáp án C: “Research in the U.S. may support Kato’s theory. In Parkfield, California earthquakes occur about every 22 years on the San Andreas fault.”
(Nghiên cứu ở Hoa Kỳ có thể hỗ trợ lý thuyết của Kato. Ở Parkfield, California, các trận động đất xảy ra khoảng 22 năm một lần trên đứt gãy San Andreas.)
+ Đáp án D: “But a colleague, Naoyuki Kato, adds that laboratory experiments indicate that a fault slips a little before it breaks. If this is true, predictions can be made based on the detection of slips. If this is true, predictions can be made based on the detection of slips.”
(Nhưng một đồng nghiệp, Naoyuki Kato, nói thêm rằng các thí nghiệm trong phòng thí nghiệm chỉ ra rằng một chỗ đứt gãy trượt một chút trước khi nó sẽ đứt vỡ ra. Nếu điều này là đúng, các dự đoán có thể được thực hiện dựa trên việc phát hiện các vết trượt. Nếu điều này là đúng, các dự đoán có thể được thực hiện dựa trên việc phát hiện các vết trượt.)
=> Bằng phương pháp loại trừ, ta chọn B.

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 33 to 37.
Earthquakes are destructive events in nature. The damage depends on the size or magnitude of the quake. There have never been so many people living in cities in quake zones, and so the worse the damage can be from a big quake, bringing fires, tsunamis, and the loss of life, property, and maybe an entire city.
We understand how earthquakes happen but not exactly where or when they will occur. Until recently, quakes seemed to occur at random. In Japan, government research is now showing that quakes can be predicted. At the Earthquake Research Institute, University of Tokyo, Koshun Yamaoka says earthquakes do follow a pattern—pressure builds in a zone and must be released. But a colleague, Naoyuki Kato, adds that laboratory experiments indicate that a fault slips a little before it breaks. If this is true, predictions can be made based on the detection of slips.
Research in the U.S. may support Kato’s theory. In Parkfield, California earthquakes occur about every 22 years on the San Andreas fault. In the 1980s, scientists drilled into the fault and set up equipment to record activity to look for warning signs. When an earthquake hit again, it was years off schedule. At first the event seemed random but scientists drilled deeper. By 2005 they reached the bottom of the fault, two miles down, and found something. Data from two quakes reported in 2008 show there were two “slips’—places where the plates widened—before the fault line broke and the quakes occurred.
We are learning more about these destructive events every day. In the future we may be able to track earthquakes and design an early-warning system. So if the next great earthquake does happen in Tokai, about 100 miles southwest of Tokyo, as some scientists think, the citizens of Tokai may have advance warning.
