1. What is the basic unit of heredity?

• A. Chromosome
• B. Cell
• C. Gene
• D. Organ

Correct answer: C

Rationale: A gene is the basic unit of heredity that carries the instructions for making proteins, which determine an organism's traits. Genes are segments of DNA located on chromosomes within the cell. While chromosomes contain many genes, a gene itself is the fundamental unit of heredity responsible for passing on genetic information from one generation to the next. Cells are the basic structural and functional units of living organisms, but genes specifically carry genetic information. Organs are composed of tissues and serve specific functions within an organism, but they are not the basic unit of heredity.

2. Which of the following is responsible for maintaining the body's circadian rhythm?

• A. Thyroid gland
• B. Pineal gland
• C. Pancreas
• D. Hypothalamus

Correct answer: B

Rationale: The pineal gland is responsible for maintaining the body's circadian rhythm by producing melatonin. Melatonin is a hormone that helps regulate the sleep-wake cycle and is essential in controlling the body's internal clock. The thyroid gland, although important for metabolism, is not directly involved in regulating circadian rhythms. The pancreas plays a role in blood sugar regulation through insulin production, not in controlling circadian rhythms. The hypothalamus is involved in regulating various bodily functions, but the pineal gland is specifically responsible for the circadian rhythm.

3. One gallon of cleaning solution requires 6 oz of ammonia. If the maintenance department needs 230 gallons of solution to clean all of the floors, how much ammonia is needed?

• A. 1380 gallons
• B. 6900 gallons
• C. 1380 oz
• D. 1400 oz

Correct answer: C

Rationale: To find out how much ammonia is needed for 230 gallons of cleaning solution, you multiply the amount of ammonia needed per gallon by the total gallons of solution required. Therefore, 230 gallons * 6 oz/gallon = 1380 oz of ammonia. Option A ('1380 gallons') and Option B ('6900 gallons') are incorrect as the question asks for the amount of ammonia needed, not the total volume of cleaning solution. Option D ('1400 oz') is incorrect as it does not correctly calculate the amount of ammonia required based on the given information.

4. What word best describes the author's attitude toward those who believe they understand money?

• A. Supportive
• B. Incriminating
• C. Excessive
• D. Patronizing

Correct answer: D

Rationale: The author's tone towards those who think they understand money is patronizing, as seen in the statement 'Many of my hearers may say, 'we understand this; this is economy, and we know economy is wealth; we know we can't eat our cake and keep it also.' Yet I beg to say that perhaps more cases of failure arise from mistakes on this point than almost any other.' This conveys a sense of superiority and belittlement, making 'Patronizing' the best word to describe the author's attitude. - Choice A, 'Supportive,' is incorrect as the author is not expressing support but rather a critical view. - Choice B, 'Incriminating,' is incorrect as the author is not accusing or blaming those who believe they understand money. - Choice C, 'Excessive,' is incorrect as it does not capture the author's attitude of looking down on others' understanding of money.

5. "I would like to go with you; however, I won’t have time." In this sentence, what part of speech is the word "however"?

• A. Preposition
• B. Conjunction
• C. Conjunctive adverb
• D. Subordinating conjunction

Correct answer: C

Rationale: The word "however" in the given sentence functions as a conjunctive adverb. Conjunctive adverbs are used to connect clauses or sentences and show relationships between them. In this case, "however" introduces a contrast between the speaker's desire to go and the lack of time, indicating a shift in the information provided.
