1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. Contact dermatitis occurs through the sense of ___________.

A. smell
B. taste
C. touch
D. sight

Correct answer: C

Rationale: Contact dermatitis occurs through the sense of touch when the skin comes into direct contact with irritants or allergens, leading to an inflammatory reaction. This condition is commonly caused by the skin being in contact with items like certain chemicals, fabrics, plants, or metals, resulting in redness, itching, and sometimes blisters. The other choices (smell, taste, sight) do not relate to the cause of contact dermatitis, which specifically involves the skin's direct contact with irritants or allergens.

3. The bad smell made him __________.

A. Gag
B. Enjoy
C. Remember
D. Attach

Correct answer: A

Rationale: The bad smell would likely make him gag, which is a physical reaction to an unpleasant odor. Gagging is a common response to strong or foul smells as the body seeks to expel the offending odor. Enjoy, Remember, and Attach do not accurately reflect a likely reaction to a bad smell.

4. Which word means TO THINK ABOUT SOMETHING BEFORE MAKING A DECISION?

A. Imply
B. Transgress
C. Allay
D. Ruminate

Correct answer: D

Rationale: The word 'ruminate' means to think deeply about something before making a decision. It specifically implies reflecting or pondering carefully on a matter, indicating a thoughtful consideration process. Choices A, B, and C are incorrect. 'Imply' means to suggest indirectly, 'transgress' means to go beyond limits or boundaries, and 'allay' means to diminish or put to rest feelings of fear or suspicion. These words do not convey the concept of thoughtful contemplation before making a decision.

5. What is the term for the word part placed before a word to change its meaning?

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

Correct answer: A

Rationale: The correct answer is 'Prefix.' A prefix is a word part that is placed before a root word to modify its meaning. In this case, a prefix changes the meaning of the root word. Choice B, 'Affix,' is a broader term that includes prefixes, suffixes, and infixes. Choice C, 'Suffix,' is a word part placed after a root word to modify its meaning, not before. Choice D, 'Vocab,' is unrelated to the word part placed before a word.
