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.
Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods – a term whose meaning varies greatly – frequently proclaim that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and more nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the preponderance of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form the basis for folklore.
Almost daily the public is besieged by claims for “no-aging” diets, new vitamins, and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains and the like.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the regular food and buy only expensive organic foods instead.
The author implies that there is cause for concern if consumers with limited incomes buy organic foods instead of conventionally grown foods because _______.
A. organic foods can be more expensive but are often no better than conventionally grown foods
B. many organic foods are actually less nutritious than similar conventionally grown foods
C. conventionally grown foods are more readily available than organic foods
D. too many farmers will stop using conventional methods to grow food crops

Câu hỏi: Tác giả ngụ ý là nếu những người tiêu dùng với thu nhập có hạn mua thực phẩm hữu cơ thay vì thực phẩm được trồng truyền thống thì nguyên nhân cần quan tâm là gì?
Clue: “So there is real cause for concern if consumers, particularly those with limited incomes, distrust the regular food and buy only expensive organic foods instead”: Vì vậy sẽ là một mối bận tâm thực sự nếu các khách hàng, đặc biệt những người với thu nhập hạn chế, không tin tưởng thực phẩm thông thường mà thay vào đó chỉ mua thực phẩm hữu cơ đắt tiền.
Phân tích: Thức ăn hữu cơ đắt tiền hơn thức ăn thông thường, khi người tiêu dùng với thu nhập có hạn tiêu tốn nhiều tiền hơn với loại thực phẩm này vì họ lầm tưởng thức ăn hữu cơ tốt hơn thì gây ra mối quan ngại. Do đó, chọn đáp án A. organic foods can be more expensive but are often no better than conventionally grown foods: thực phẩm hữu cơ có thể đắt tiền hơn nhưng thường không tốt hơn thực phẩm được trồng truyền thống.
