1. If there are 128 ounces in 1 gallon, how many ounces are in 2.5 gallons?

• A. 256 ounces
• B. 320 ounces
• C. 400 ounces
• D. 250 ounces

Correct answer: B

Rationale: To find the total number of ounces in 2.5 gallons, multiply the number of gallons by the number of ounces per gallon: 2.5 gallons × 128 ounces/gallon = 320 ounces. The correct answer is 320 ounces. Choice C (400 ounces) is incorrect because multiplying 2.5 by 128 gives 320, not 400. Choice D (250 ounces) is also incorrect as it seems to be a miscalculation.

2. Which gland produces melatonin?

• A. Pineal gland
• B. Thyroid gland
• C. Adrenal gland
• D. Pituitary gland

Correct answer: A

Rationale: The correct answer is the Pineal gland. This gland is responsible for producing melatonin, a hormone that helps regulate the sleep-wake cycle. Melatonin production is influenced by exposure to light, with levels typically rising in the evening to promote sleep and falling in the morning to aid wakefulness. The Thyroid gland (choice B) produces hormones that regulate metabolism, the Adrenal gland (choice C) produces hormones like adrenaline and cortisol, and the Pituitary gland (choice D) controls several other glands in the endocrine system.

3. How many milliliters are in 3 liters?

• A. 300 milliliters
• B. 3000 milliliters
• C. 1500 milliliters
• D. 300 milliliters

Correct answer: B

Rationale: The correct answer is B: 3000 milliliters. There are 1,000 milliliters in a liter. Therefore, 3 liters = 3 × 1,000 = 3,000 milliliters. Choice A (300 milliliters) is incorrect as it represents the conversion of 0.3 liters, not 3 liters. Choice C (1500 milliliters) is incorrect as it is halfway between the correct answer and a common mistake of confusing liters with milliliters. Choice D (300 milliliters) is incorrect as it is the conversion of 0.3 liters, not 3 liters.

4. What is stated about Benjamin Franklin's role in Daylight Savings Time?

• A. Benjamin Franklin invented Daylight Savings Time.
• B. Benjamin Franklin proposed the concept of Daylight Savings Time.
• C. Benjamin Franklin opposed Daylight Savings Time.
• D. Benjamin Franklin had no connection to Daylight Savings Time.

Correct answer: B

Rationale: Benjamin Franklin is credited with proposing the idea of Daylight Savings Time, as stated in the extract. However, it was not implemented during his lifetime. Choice A is incorrect because he proposed, not invented, Daylight Savings Time. Choice C is incorrect as there is no mention of Franklin opposing it. Choice D is incorrect as the extract clearly states his connection to the proposal of Daylight Savings Time.

5. How do animal cells divide?

• A. Through a contractile ring
• B. Via a cell plate
• C. Both methods
• D. None of the above

Correct answer: A

Rationale: Animal cells divide through a contractile ring made of actin and myosin filaments. The ring contracts, pinching the cell membrane in the middle to form two daughter cells. Plant cells use a cell plate due to their rigid cell walls, making choices B and C incorrect. Choice D is incorrect as animal cells do use the contractile ring method for division.
