Đáp án A
Dịch đề: Trong đoạn 3, tác giả đã đề cập đến tất cả các vật liệu nguy hiểm sau đây được tìm thấy trong một mảnh vỡ từ một địa điểm phá hủy NGOẠI TRỪ_____________.
A. Xenluloza B. Thủy ngân
C. Amiăng D. chì
Trích bài: If the debris from the demolition contains hazardous materials that are harmful to the environment or to the consumer, such as asbestos, then the material is not salvageable. In new “green” construction, insulation that once asbestos- based can be replaced with recycled denim or constructed with cellulose-a fibrous material found in paper products .The same- assessment applies to wood or wallboard painted with toxic lead-based paints. In addition, gas-flow regulators and meters on both water and gas heating systems constructed prior to 1961 must be carefully evaluated to determine that they do not contain dangerous substances such as mercury.
Tạm dịch: Nếu các mảnh vụn từ việc phá hủy có chứa các vật liệu nguy hiểm có hại cho môi trường hoặc người tiêu dùng, chẳng hạn như amiăng, thì vật liệu này không thể tận dụng được. Trong xây dựng xanh mới, cách nhiệt đã từng dựa vào amiăng có thể được thay thế bằng denim tái chế hoặc được chế tạo bằng cellulose - một vật liệu sợi có trong các sản phẩm giấy. Đánh giá tương tự áp dụng cho gỗ hoặc tấm tường được sơn bằng sơn có chứa chì độc hại. Ngoài ra, các bộ điều chỉnh lưu lượng khí và đồng hồ đo trên cả hệ thống làm nóng nước và không khí được xây dựng trước năm 1961 phải được đánh giá cẩn thận để xác định rằng chúng không chứa các chất nguy hiểm như thủy ngân.
Như vậy amiang, thủy ngân và chì là các chất độc hại ngoài trừ Xenluloza - không được đề cập

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.
Accidents do not occur at random. People eighty-five years of age and older are twenty-two times likely to die accidentally than are children five to nine years old. The risk for native Americans is four times that for Asian-Americans and twice that for white Americans or African-Americans. Males suffer accidents at more than twice the rate of females, in part because they are more prone to risky behavior. Alaskans are more than three times as likely as Rhode Islanders to die in an accident. Texans are twenty- one times more likely than New Jerseyites to die in a natural disaster. Among the one hundred most populous counties, Kern County, California (Bakersfield), has an accident fatality rate three times greater than Summit County, Ohio (Akron).
Accidents happens more often to poor people. Those living in poverty receive inferior medical care, are more apt to reside in houses with faulty heating and electrical systems, drive older cars with fewer safety features, and are less likely to use safety belts. People in rural areas have more accidents than city or suburban dwellers because farming is much riskier than working in a factory or office and because emergency medical services are less readily available. These two factors - low income and rural residence - may explain why the south has a higher accident rate than the north.
