1. Based on the contextual usage of this word, what is the most likely meaning of the prefix ante-?

• A. again
• B. good
• C. before
• D. together

Correct answer: C

Rationale: The prefix 'ante-' is commonly used to refer to something that comes before something else in terms of time, order, or position. In the provided sentence, the antechamber is described as a waiting area 'before' guests were allowed into the main hall. This usage indicates that 'ante-' in this context means 'before.' The other choices are incorrect: 'again' implies repetition, 'good' is unrelated, and 'together' does not fit the context of preceding or coming before something else.

2. What determines the final velocity of a block sliding down a frictionless inclined plane?

• A. The length of the incline
• B. The angle of the incline
• C. The mass of the block
• D. All of the above

Correct answer: B

Rationale: The final velocity of a block sliding down a frictionless inclined plane is determined by the angle of the incline. The angle directly impacts the acceleration of the block, affecting the final velocity it attains at the bottom. The length of the incline and the mass of the block do not play a direct role in determining the final velocity. Therefore, the correct answer is the angle of the incline (Choice B). Choices A and C are incorrect because the length of the incline and the mass of the block do not have a direct influence on the final velocity of the block in this scenario.

3. In which of the following words does the suffix make the root word an adjective?

• A. Created
• B. Pointing
• C. Childlike
• D. Suburbanite

Correct answer: C

Rationale: 'Childlike' is an adjective formed by adding the suffix '-like' to the noun 'child.' The suffix '-like' is commonly used to transform a noun into an adjective by indicating a resemblance or characteristic associated with the root noun. Choices A, B, and D do not follow the same pattern. 'Created' is a past participle, 'pointing' is a present participle, and 'suburbanite' is a noun derived from 'suburban.' Therefore, 'Childlike' is the only word where the suffix directly converts the root word into an adjective.

4. What are the subdivisions of the dorsal cavity, located at the back of the human body?

• A. Cranial and spinal
• B. Dorsal and ventral
• C. Lateral and proximal
• D. Inferior and superior

Correct answer: A

Rationale: The correct answer is A: Cranial and spinal. The dorsal cavity, situated at the back of the human body, is divided into the cranial cavity (housing the brain) and the spinal cavity (housing the spinal cord). Choices B, C, and D are incorrect as they do not represent the correct subdivisions of the dorsal cavity. Option B (Dorsal and ventral) is incorrect as it confuses the dorsal cavity with the dorsal and ventral body planes. Option C (Lateral and proximal) and option D (Inferior and superior) are incorrect as they refer to different anatomical terms that do not apply to the subdivisions of the dorsal cavity.

5. How many chromosomes must a normal human sperm cell contain?

• A. An X chromosome.
• B. A Y chromosome.
• C. 23 chromosomes.
• D. Both an X and Y chromosome.

Correct answer: C

Rationale: A normal human sperm cell contains a total of 23 chromosomes, half the number found in a typical human cell which has 46 chromosomes. This includes 22 autosomes and one sex chromosome, which can be either an X or a Y chromosome. Therefore, the correct answer is that a normal human sperm cell must contain 23 chromosomes. Choices A and B are incorrect because a single sex chromosome alone does not represent the total number of chromosomes in a sperm cell. Choice D is incorrect because a sperm cell carries only one sex chromosome, either X or Y, not both.
