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:

The suffix "-uous" (a variant of "-ous") typically forms adjectives that describe having a quality or characteristic. "Impetuous" comes from the Latin root "impetuosus" meaning impulsive.

• Option 2 refers to a person (uses "someone"), which matches suffixes like "-er/-or", not "-uous".
• Option 3 has the opposite meaning of impetuous.
• Option 4 focuses on a state/condition, but "-uous" more directly describes the quality of the action/behavior itself, while option 1 accurately links the suffix's function to the meaning of having the quality of impulsive, emotional action.

Answer:

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