1. What is the crystalline compound that is a product of protein metabolism known as?

• A. uracil
• B. urine
• C. ureter
• D. urea

Correct answer: D

Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.

2. Long before his death, Pablo Picasso became one of the most important artists in history.

• A. become
• B. became
• C. been
• D. had become

Correct answer: B

Rationale: The correct answer is 'Became.' In this sentence, we need the simple past tense 'became' to describe the action that occurred in the past. 'Become' (choice A) is incorrect as it is the base form of the verb and doesn't fit the sentence structure. 'Been' (choice C) is incorrect as it is the past participle and doesn't match the sentence context. 'Had become' (choice D) is unnecessary as the sentence doesn't require the past perfect tense.

3. Select the word that means 'on both sides.'

• A. bilateral
• B. insufficient
• C. bicuspid
• D. congruent

Correct answer: A

Rationale: The correct answer is 'bilateral.' 'Bilateral' means having two sides or affecting both sides. 'Insufficient' means not enough or inadequate, 'bicuspid' refers to a two-pointed tooth, and 'congruent' means in agreement or harmony. Therefore, 'bilateral' is the only word among the choices that specifically relates to being on both sides.

4. The electrolytes in human bodies include sodium, potassium, calcium, and ___________, among others.

• A. magnesium
• B. manganese
• C. magnetite
• D. manganite

Correct answer: A

Rationale: Magnesium is another essential electrolyte in the human body, along with sodium, potassium, and calcium. Magnesium plays a crucial role in various bodily functions, including muscle and nerve function, regulating blood pressure, and supporting the immune system. Manganese (Choice B), magnetite (Choice C), and manganite (Choice D) are not electrolytes found in the human body. Manganese is a mineral but not an electrolyte, while magnetite and manganite are compounds and not essential electrolytes for bodily functions.

5. There was no _____ for the way she treated her boyfriend.

• A. Alibi
• B. Rational
• C. Reasonable
• D. Justification

Correct answer: D

Rationale: The correct answer is 'D: Justification.' Justification means showing that an action is reasonable or right. In this context, it implies that there was no valid reason or excuse for the way she treated her boyfriend. Choices A, B, and C are incorrect. An 'alibi' is an excuse to explain one's whereabouts during a crime, not applicable here. 'Rational' means based on reason or logic, which does not fit the context of the sentence. 'Reasonable' means fair and sensible, but the sentence suggests a lack of valid explanation rather than fairness or sensibility.
