1. If these statements above are factual, which of the following statements must be correct?

• A. Outspending other countries on education has benefits beyond standardized tests.
• B. The US education system is corrupt and ineffective.
• C. The standardized math tests do not accurately reflect American proficiency.
• D. Spending more money does not guarantee success on standardized tests.

Correct answer: D

Rationale: Based on the information provided in the extract, it is evident that despite the United States spending a substantial amount on education, it does not translate to top performance in standardized math tests. Countries spending less outperformed the United States, indicating that spending more money does not guarantee success on standardized tests. Choice A is incorrect because the extract does not specify benefits beyond tests. Choice B is incorrect as the extract does not explicitly state that the US education system is corrupt and broken. Choice C is incorrect as the extract talks about the performance on standardized math tests rather than American proficiency in general.

2. Which transport mechanism uses vesicles to move materials out of the cell?

• A. Endocytosis
• B. Active transport
• C. Diffusion
• D. Exocytosis

Correct answer: D

Rationale: Exocytosis is the transport mechanism that uses vesicles to move materials out of the cell. Vesicles carry substances to the cell membrane, fuse with it, and release their contents outside the cell. This process is essential for secreting molecules such as hormones, enzymes, or neurotransmitters. Endocytosis, on the other hand, is the process of bringing materials into the cell by engulfing them in vesicles. Active transport involves the movement of molecules across a cell membrane against their concentration gradient, requiring energy. Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

3. Which of the following pairs of words includes a suffix that changes the meaning of the second word from the first?

• A. fort; fortification
• B. mount; dismount
• C. flee; fleeing
• D. fame; famous

Correct answer: D

Rationale: The correct answer is D. Adding the suffix '-ous' to 'fame' changes it to an adjective, 'famous,' altering the meaning of the word. Choice A is incorrect because 'fortification' is derived from 'fort' but does not change its meaning significantly. Choice B is incorrect as 'dismount' is related to 'mount' but signifies the opposite action rather than a change in meaning. Choice C is incorrect as 'fleeing' is simply the present participle form of 'flee' and does not alter its fundamental meaning.

4. 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.

5. Which class of hormones is most likely to be released after a serious injury?

• A. Acetylcholine
• B. Oxytocin
• C. Luteinizing hormone
• D. Endorphins

Correct answer: D

Rationale: Endorphins are the class of hormones most likely to be released after a serious injury. Endorphins are the body's natural pain relievers and are produced in response to stress or pain, helping to alleviate discomfort and promote a sense of well-being. Acetylcholine is a neurotransmitter, not a hormone. Oxytocin is mainly involved in childbirth and lactation. Luteinizing hormone is involved in reproductive functions such as ovulation. Therefore, choices A, B, and C are incorrect in the context of a hormone release following a serious injury.
