1. What is the best meaning of Pernicious?

• A. Harmless
• B. Destructive
• C. Helpful
• D. Harmful

Correct answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious is an adjective that describes something that is extremely harmful or destructive. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Helpful,' is a positive term and does not align with the meaning of pernicious. Choice D, 'Harmful,' is a similar term to pernicious but lacks the emphasis on the severe and damaging nature of the word.

2. What is the word part placed before a word to change its meaning?

• A. Prefix
• B. Affix
• C. Suffix
• D. Vocab

Correct answer: A

Rationale: A prefix is the correct answer. A prefix is a word part attached at the beginning of a word to modify its root word, changing the definition or grammatical function of the word. Examples of prefixes include "un-" in "unhappy," "re-" in "redo," and "pre-" in "preview." Choice B, "Affix," is incorrect because while a prefix is a type of affix, not all affixes are prefixes. Choice C, "Suffix," is incorrect as a suffix is a word part added at the end of a word to change its meaning. Choice D, "Vocab," is incorrect as it refers to vocabulary or words related to a particular subject rather than a word part placed before a word.

3. What happens in a single displacement reaction?

• A. A compound decomposes into two substances.
• B. An active element displaces a less active element.
• C. A precipitate solid forms from the reaction of two solutions.
• D. The oxidation states of atoms in the reactants change.

Correct answer: B

Rationale: In a single displacement reaction, an active element displaces a less active element in a compound. This process involves one element replacing another in a compound, resulting in the formation of a new compound. Option A is incorrect because a single displacement reaction does not involve the decomposition of a compound into two substances. Option C is incorrect because it describes a precipitation reaction, not a single displacement reaction. Option D is incorrect because it describes oxidation-reduction reactions, not specifically single displacement reactions.

4. What does 'Occluded' mean?

• A. Open
• B. Closed or obstructed
• C. Partially obstructed
• D. Expanded

Correct answer: B

Rationale: The term 'Occluded' means something is closed or obstructed, not open as in choice A. It is more than just partially obstructed as in choice C. It does not mean expanded as in choice D. Therefore, the correct answer is B, 'Closed or obstructed.'

5. What is the best description for the term anodyne?

• A. Emulsified
• B. Liquefied
• C. Contaminated
• D. Painkilling

Correct answer: D

Rationale: The term 'anodyne' refers to something that relieves or alleviates pain or discomfort. Therefore, the best description for anodyne is 'painkilling.' Choices A (Emulsified), B (Liquefied), and C (Contaminated) are incorrect as they do not accurately represent the meaning of anodyne.
