1. Which of the following foods or beverages would offer the most nutrients per calorie?

• A. chicken
• B. wine
• C. white bread
• D. broccoli

Correct answer: D

Rationale: Broccoli is indeed the correct answer. Broccoli is considered nutrient-dense, meaning it provides a significant amount of essential nutrients like vitamins, minerals, and fiber while being relatively low in calories. On the other hand, choices A, B, and C are not as nutrient-dense as broccoli. Chicken can be nutritious but may vary in nutrient content depending on the cut and preparation method. Wine, although containing antioxidants like resveratrol, is not a significant source of essential nutrients. White bread is often low in nutrients and fiber compared to whole grain options, making it less nutrient-dense than broccoli.

2. Has Healthy People (HP 2020), issued by the U.S. Department of Health and Human Services, resulted in a reduction of deaths from cardiovascular disease, stroke, and some cancers, as well as decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years?

• A. Yes, both statements are true.
• B. No, both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: B

Rationale: Both statements are false. While Healthy People (HP 2020) has contributed to a reduction in deaths from cardiovascular disease, stroke, and some cancers, it did not result in decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years. Therefore, the correct answer is B. Choice A is incorrect because the second statement is false. Choice C is incorrect as the first statement is also false. Choice D is incorrect as the second statement is false.

3. Where does carbohydrate digestion begin?

• A. Mouth
• B. Esophagus
• C. Stomach
• D. Small intestine

Correct answer: A

Rationale: Carbohydrate digestion begins in the mouth. The enzyme amylase, found in saliva, starts the process by breaking down starches into sugars. The esophagus is a passageway for food to reach the stomach and does not participate in digestion. The stomach mainly digests proteins and is not the primary site for carbohydrate breakdown. While the small intestine does play a crucial role in digesting carbohydrates, it is not where the process initiates. Therefore, the correct answer is the mouth.

4. Which of the following is not a desirable blood lipid value?

• A. low total cholesterol
• B. high LDL
• C. high HDL
• D. low blood triglycerides

Correct answer: B

Rationale: The correct answer is B. High levels of LDL (low-density lipoprotein) cholesterol are undesirable as they are associated with an increased risk of cardiovascular disease. Therefore, low total cholesterol (choice A), high HDL (choice C), and low blood triglycerides (choice D) are considered desirable blood lipid values. Low total cholesterol is beneficial as high levels can increase the risk of heart disease. High HDL cholesterol is considered good as it helps remove LDL cholesterol from the arteries. Low blood triglycerides are also preferred as high levels are associated with an increased risk of heart disease.

5. What is the first step in the scientific method?

• A. Conduct an experiment
• B. Make an observation and ask a question
• C. Formulate a hypothesis
• D. Reach a consensus

Correct answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.
