1. Subtract and simplify: -5 - (-6) =

• A. ½
• B. 1⅜
• C. 1
• D. 1⅔

Correct answer: C

Rationale: To simplify the expression -5 - (-6), we can rewrite it as -5 + 6 (since subtracting a negative number is equivalent to adding its positive counterpart). This gives us -5 + 6 = 1. Therefore, the correct answer is 1. Choice A, ½, is incorrect because the subtraction of a negative number results in a positive number. Choices B and D are also incorrect as they do not match the simplified result of -5 - (-6), which is 1.

2. The phases of mitosis include:

• A. Prophase, interphase, metaphase, anaphase, and telophase
• B. Prophase, prophase, metaphase, anaphase, and cytokinesis
• C. Prophase, prometaphase, metaphase, anaphase, and telophase
• D. Prophase, interphase, prophase, anaphase, and telophase

Correct answer: C

Rationale: The correct phases of mitosis are prophase, prometaphase, metaphase, anaphase, and telophase. Prophase is the first phase where chromatin condenses into chromosomes, the nuclear envelope breaks down, and the mitotic spindle forms. Prometaphase follows prophase, involving the full disintegration of the nuclear envelope and the attachment of spindle fibers to the kinetochores of the chromosomes. Metaphase is where chromosomes align along the metaphase plate. Anaphase is the phase where sister chromatids separate and move towards opposite poles. Telophase marks the final stage of mitosis, involving the decondensation of chromosomes and the reformation of the nuclear envelope. Choice A is incorrect because it includes interphase, which is not a phase of mitosis. Choice B is incorrect as it repeats prophase, which is the initial phase. Choice D is incorrect because it includes interphase and repeats prophase.

3. Which form of fermentation is used to produce beer?

• A. Lactic acid fermentation
• B. Acetic acid fermentation
• C. Propionic acid fermentation
• D. Ethyl alcohol fermentation

Correct answer: D

Rationale: The correct answer is D, Ethyl alcohol fermentation. During beer production, yeast metabolizes sugars in the wort to produce ethanol (ethyl alcohol) and carbon dioxide, which are responsible for the alcohol content and carbonation in beer. Choices A, B, and C are incorrect because lactic acid fermentation produces lactic acid, acetic acid fermentation produces acetic acid, and propionic acid fermentation produces propionic acid, none of which are used in the production of beer.

4. Which word correctly completes the sentence? 'The men and women of the graduating class ___ their caps in the air.'

• A. Thorough
• B. Through
• C. Threw
• D. Throwing

Correct answer: C

Rationale: The correct answer is 'C: Threw.' In this sentence, we need the past tense form of the verb 'throw' to show the action that occurred. Therefore, 'threw' is the correct choice. 'Thorough' (choice A) means complete or exhaustive, which doesn't fit the context of the sentence. 'Through' (choice B) is a preposition or an adverb, not the correct verb form. 'Throwing' (choice D) is the present participle form and does not match the past tense needed in the sentence.

5. What motivates athletes to participate in the Summer Olympic Games?

• A. Athletes strive for winning medals.
• B. Athletes seek opportunities to travel the world.
• C. Athletes aim for financial gain.
• D. Athletes feel patriotic pride.

Correct answer: D

Rationale: The main reason athletes want to participate in the Summer Olympic Games is often driven by a sense of patriotic pride. Representing their country and showcasing their skills on an international platform instills a deep sense of national pride in athletes. While winning medals is a significant goal for many athletes, the primary motivation to participate in the Olympics is often rooted in representing their nation. Choices A, B, and C are incorrect because although athletes may aspire to win medals, travel the world, or earn money through endorsements, the core driving factor for most athletes in the Summer Olympics is the patriotic pride of representing their country.
