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 word “others” refers to _______.

A. advantages

B. advocates

C. organic foods

D. products

Đáp án A.

Key words: advocates, closest meaning.

Câu hỏi: Từ “Advocates” gần nghĩa nhất với từ nào dưới đây?

Clue: “Advocates of organic foods – a term whose meaning varies greatly – frequently proclaim that such products are safer and more nutritious than others”: Những người ủng hộ thực phẩm hữu cơ, một thuật ngữ với nghĩa vô cùng đa dạng, thường xuyên tuyên bố rằng các thực phẩm này an toàn hơn và có nhiều dinh dưỡng hơn các sản phẩm khác.

Phân tích: Vì những người “advocates” nghĩ sản phẩm thức ăn hữu cơ an toàn và nhiều dinh dưỡng, đều là những từ tích cực dành cho loại sản phẩm này, nên có thể suy luận đây là những người ưa chuộng sản phẩm này. “Advocates” là những người tán thành, ủng hộ một ý tưởng hoặc quan điểm nào đó.

Xét các đáp án:

A. Proponents: người đề xướng – một người đề xướng ra một ý tưởng nghĩa là người đó tán thành ý tưởng đó – hợp lý.

B. Merchants: Thương gia, người mua bán hàng hóa – không hợp lý.

C. Inspectors: Thanh tra, người điều tra – không hợp lý.
