1. Choose the meaning of the word 'quarantine' in the following sentence: 'The patients are under quarantine until further notice.'

• A. A specialist's care
• B. Experimental drug therapy
• C. Imprisonment in a rehabilitation unit
• D. Confinement away from the general population

Correct answer: D

Rationale: In this sentence, the word 'quarantine' is used to convey the idea that the patients are isolated or separated from the general population. Quarantine is often implemented to prevent the spread of diseases or infections, and in this context, it implies confinement or isolation to ensure the safety of others. The other choices are incorrect because 'A' refers to specialized medical attention, 'B' refers to a specific medical treatment, and 'C' implies being held against one's will in a rehab facility, none of which capture the meaning of 'quarantine' as used in the sentence provided.

2. Which type of muscle tissue is under voluntary control?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Cardiac muscle

Correct answer: C

Rationale: Skeletal muscle is under voluntary control, allowing conscious regulation for activities like walking and lifting. This type of muscle is attached to bones and is responsible for movement in the body. Smooth muscle (Choice A) is involuntary and found in organs like the stomach and intestines. Cardiac muscle (Choice B and D) is also involuntary and specific to the heart, contracting rhythmically to pump blood, but it is not under conscious control.

3. Which sentence is the clearest?

• A. At the age of seven, my mother moved me to a new school.
• B. When I was seven, my mother moved me to a new school.
• C. At the age of seven, I moved my mother to a new school.
• D. My mother, at the age of seven, moved me to a new school.

Correct answer: B

Rationale: Option B, 'When I was seven, my mother moved me to a new school,' is the clearest sentence as it directly and clearly states that when the speaker was seven, their mother moved them to a new school. This sentence clearly indicates the age of the speaker and who initiated the action, making it the most precise and easy to understand among the choices. Choices A, C, and D are incorrect because they either incorrectly position the age or the action initiator, leading to ambiguity and confusion in the sentence.

4. Which one of the following best describes the function of a cell membrane?

• A. It controls the substances entering and leaving the cell.
• B. It maintains the cell's shape.
• C. It controls the substances entering the cell.
• D. It supports the cell's structures.

Correct answer: A

Rationale: The correct answer is A. The function of a cell membrane is to control the substances entering and leaving the cell. The cell membrane is selectively permeable, allowing it to regulate the movement of ions and molecules in and out of the cell to maintain internal balance and proper function. Choice B is incorrect because while the cell membrane does provide some structural support, its primary function is not to maintain the cell's shape. Choice C is incorrect because the cell membrane controls both the substances entering and leaving the cell, not just those entering. Choice D is incorrect as the primary function of the cell membrane is not to support the cell's structures but to regulate the movement of substances.

5. What can stop the penetration of gamma radiation?

• A. Aluminum foil
• B. Glass
• C. Several feet of concrete
• D. Piece of paper

Correct answer: C

Rationale: Gamma radiation is highly penetrative and requires dense materials to block it effectively. While aluminum foil and glass are not sufficient to stop gamma radiation, several feet of concrete is needed due to its high density and ability to absorb gamma radiation effectively. A piece of paper is too thin and lacks the density required to block gamma radiation, making it an ineffective shield.
