Question

by studying the suffix, the reader can determine that \impetuous\ most likely means

• \having the quality of acting impulsive or with emotion.\
• \someone who is filled with impulsiveness and emotion.\
• \someone who acts without impulsiveness or emotion.\
• \having a state or condition that is impulsive or emotional.\

Explanation:

1. Analyze the suffix of "impetuous": The suffix "-ous" typically means "having the quality of" or "full of".
2. Analyze the root "impetu-" (related to "impulse").
3. Evaluate each option:

• Option 1: "having the quality of acting impulsive or with emotion." matches the suffix meaning ("-ous" for quality) and the root's implication of impulse/emotion.
• Option 2: "-ous" does not denote a person (that's more for "-er"/"-or" suffixes), so this is incorrect.
• Option 3: The prefix "im-" here (in "impetuous") does not mean "without" in this context (it's from Latin "impetus" meaning impulse, not a negative prefix like "im-" in "impossible"). So this is wrong.
• Option 4: "-ous" means quality, not state/condition (state/condition is more for "-ness" etc.). So this is incorrect.

Answer:

A. "having the quality of acting impulsive or with emotion."
