1. Which of the following is the main organ responsible for producing bile?

• A. Liver
• B. Gallbladder
• C. Pancreas
• D. Stomach

Correct answer: A

Rationale: The liver is the main organ responsible for producing bile. Bile, a greenish-yellow fluid, is produced by the liver and stored in the gallbladder. Its primary function is to aid in the digestion and absorption of fats in the small intestine. When needed, the gallbladder releases bile into the small intestine to facilitate fat digestion. The pancreas produces digestive enzymes and insulin, not bile, making choice C incorrect. The stomach's primary role is to digest food through gastric juice secretion, making choice D incorrect. Therefore, the correct answer is the liver, as it is the main organ responsible for bile production.

2. What is the estimated total amount of money the roommates used to purchase the gift?

• A. $34
• B. $35
• C. $36
• D. $37

Correct answer: C

Rationale: To find the total amount spent by the roommates, you need to add up the individual amounts each roommate contributed. Anna contributed $18, Liz contributed $12, and Jane contributed $6. Adding these amounts together gives us $18 + $12 + $6 = $36. Therefore, the correct answer is $36. Option A ($34), Option B ($35), and Option D ($37) are incorrect as they do not match the correct calculation of the total amount spent by the roommates.

3. Which of the following is a complex sentence?

• A. When skywriting, a pilot flies a small aircraft in specific, particular formations, creating large letters visible from the ground.
• B. The public defense attorney was able to maintain her optimism despite her dearth of courtroom wins, her lack of free time, and her growing list of clients.
• C. Because the distance between stars in the galaxy is far greater than the distance between planets, interstellar travel is expected to be an even bigger challenge than interplanetary exploration.
• D. Invented in France in the early nineteenth century, the stethoscope underwent a number of reiterations before the emergence of the modern form of the instrument in the 1850s.

Correct answer: C

Rationale: A complex sentence has one independent clause and at least one dependent clause connected by a subordinating conjunction or a relative pronoun. In choice C, the sentence 'Because the distance between stars in the galaxy is far greater than the distance between planets' is a dependent clause introduced by the subordinating conjunction 'Because,' while the rest of the sentence 'interstellar travel is expected to be an even bigger challenge than interplanetary exploration' forms the independent clause. This combination of an independent clause and a dependent clause makes choice C a complex sentence. Choices A, B, and D do not contain both an independent and dependent clause connected in the way that choice C does, thus they do not qualify as complex sentences.

4. How many liters are in 750 milliliters?

• A. 7.5 liters
• B. 0.75 liters
• C. 0.0075 liters
• D. 0.075 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 750 milliliters divided by 1000 equals 0.75 liters. Choice A (7.5 liters) is incorrect as it is off by a factor of 10. Choice C (0.0075 liters) is incorrect as it is off by a factor of 100. Choice D (0.075 liters) is incorrect as it is off by a factor of 10.

5. Which hormone is released by the pituitary gland?

• A. Estrogen
• B. Luteinizing Hormone
• C. Progesterone
• D. Testosterone

Correct answer: B

Rationale: The correct answer is B: Luteinizing Hormone. The pituitary gland releases luteinizing hormone, which plays a crucial role in reproductive functions by stimulating ovulation in females and testosterone production in males. Choice A, Estrogen, is incorrect as estrogen is mainly produced by the ovaries. Choice C, Progesterone, is incorrect as progesterone is produced by the corpus luteum in the ovaries and the placenta during pregnancy. Choice D, Testosterone, is incorrect as testosterone is produced primarily in the testes in males and in smaller amounts in the ovaries and adrenal glands in females.
