1. What is the term for a solution with a pH value less than 7?

• A. Acidic
• B. Neutral
• C. Alkaline
• D. Basic

Correct answer: A

Rationale: Solutions with a pH less than 7 are classified as acidic. pH values below 7 indicate an acidic solution, which means it has a higher concentration of hydrogen ions. Choices B, C, and D are incorrect as they describe neutral (pH 7), alkaline (pH greater than 7), and basic (another term for alkaline), respectively, which are not applicable to solutions with a pH less than 7.

2. Many _____ books are popular among adults these days.

• A. Children's
• B. Childrens's
• C. Childrens'
• D. Childrens

Correct answer: A

Rationale: The correct answer is 'Children's.' In this context, 'Children's' is the correct possessive form to indicate that the books belong to or are associated with children. Choice B ('Childrens's') is incorrect due to the unnecessary extra 's' after the apostrophe. Choice C ('Childrens'') is wrong as it is missing the apostrophe to show possession. Choice D ('Childrens') is incorrect as it is missing the apostrophe and does not form the possessive form correctly.

3. What best describes the plot in fiction?

• A. The main sequence of events or the storyline
• B. Character development
• C. The time and place of the story
• D. The events in the story that are true

Correct answer: A

Rationale: The correct answer is A: 'The main sequence of events or the storyline.' The plot of a fiction story refers to the series of events that make up the storyline, including the rising action, climax, and resolution. It focuses on what happens in the story rather than the development of characters (choice B), the time and place setting (choice C), or events that are factually true (choice D), which are elements distinct from the plot.

4. Which structure serves as the electrical stimulator of the cardiac muscle?

• A. The sinoatrial node
• B. The left ventricle
• C. The aorta
• D. The tricuspid valve

Correct answer: A

Rationale: The correct answer is the sinoatrial node. This node, also referred to as the pacemaker of the heart, is responsible for initiating the electrical impulses that stimulate cardiac muscle contractions. It plays a crucial role in setting the pace and rhythm of the heart's contractions. Choices B, C, and D (the left ventricle, the aorta, and the tricuspid valve, respectively) do not serve as the primary electrical stimulator of the cardiac muscle. While the left ventricle is a chamber of the heart that pumps oxygenated blood to the body, the aorta is the main artery that carries blood away from the heart, and the tricuspid valve is a one-way valve that ensures blood flows properly through the heart, none of these structures initiate the electrical impulses that cause the cardiac muscle to contract.

5. If 3/4 of students at a university major in nursing and 1/3 of those students complete the program, how many will complete the program if 100 students are in the incoming class?

• A. 75
• B. 20
• C. 15
• D. 5

Correct answer: C

Rationale: Out of the 100 students, 3/4 (75 students) major in nursing. Since 1/3 of those students complete the program, 1/3 * 75 = 25 students will complete the program. Therefore, 25 students out of the 100 incoming class will complete the program, making choice C (15) the correct answer. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the given information.
