1. Which term refers to the relaxation of the heart muscle?

• A. Diastole
• B. Systole
• C. Asystole
• D. Cardiastole

Correct answer: A

Rationale: The correct answer is A: Diastole. Diastole is the phase of the heartbeat when the heart muscle relaxes, allowing the chambers to fill with blood. Systole, on the other hand, refers to the contraction phase of the heart when it pumps blood out. Asystole is the absence of heart contractions, often referred to as cardiac arrest. Cardiastole is not a recognized medical term in relation to heart muscle relaxation, making it an incorrect choice.

2. Which enzyme breaks down carbohydrates like starches and sugars in the mouth?

• A. Pepsin
• B. Lipase
• C. Amylase

Rationale: The correct answer is Amylase. Amylase is the enzyme responsible for breaking down carbohydrates like starches and sugars in the mouth. Pepsin is a digestive enzyme that breaks down proteins in the stomach, lipase breaks down fats, and trypsin is another enzyme that breaks down proteins in the small intestine. Therefore, choices A, B, and D are incorrect for this question.

3. Which of the following is not an example of something the author of Passage 1 claims travels from place to place through human environment?

• A. Fairy tales
• B. Language
• C. Ideas
• D. Foods

Correct answer: D

Rationale: The correct answer is D: Foods. The author of Passage 1 mentions language, ideas, and goods as examples of things that travel from place to place through the movement of peoples. There is no mention of food in the passage as something that is spread through human interaction. Fairy tales, language, and ideas are specifically highlighted in the text as elements that are transmitted through human interaction. While foods can be exchanged between cultures, the passage does not discuss them in the context of spreading through human interaction, making it the correct answer. Choice A (Fairy tales), B (Language), and C (Ideas) are all supported by the text as examples of things that travel through human environments, unlike food.

4. How many milliliters are in 0.5 liters?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: To convert from liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters x 1000 = 500 milliliters. This conversion is common in various contexts where different units of volume are used. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to milliliters.

5. What part of speech is the word 'results' in the sentence 'The students eagerly awaited the results'?

• A. Verb
• B. Noun
• C. Adjective
• D. Adverb

Correct answer: B

Rationale: In this sentence, 'results' is the direct object of the verb 'awaited,' functioning as a noun. Hence, option B, 'Noun,' is correct. The students were eagerly waiting for what? The results - which makes 'results' a noun in this context. Choices A, C, and D are incorrect. 'Results' is not describing a verb, an adjective, or an adverb in the sentence; it is the object of the students' anticipation, indicating a noun.
