Question

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 from 36 to 42.

          Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose ans amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person’s diet. This translates to about 75-100 grams of carbohydrates per day.

          A diet that is deficient in carbohydrates can have an adverse effect on a person’s health. When the  body lacks a sufficient amount of carbohydrates, it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a build-up of ketones in the body that causes fatigue, lethargy, and bad breath

According to the passage, what do most nutritionists suggest?

A. Sufficient carbohydrates will prevent gluconeogenesis.

B. Carbohydrates are simple sugars called glucose.

C. Carbohydrates should make up about a quarter of a person’s daily diet.

D. Carbohydrates should be eaten in very small quantities
