we were taught that a gibe can cause someone to be deeply hurt.

Explanation:

To determine the correct sentence, we analyze the dictionary definition of "gibe" (v.): to make taunting, heckling, or jeering remarks.

• In "His thoughtless gibes...", "gibes" is a noun (plural), but the definition is for the verb form.
• In "Critics of the mayor often gibe...", "gibe" is used as a verb, and the action of critics making remarks about the mayor’s articulation matches the definition of taunting/jeering remarks.
• In "The unfair gibe...", "gibe" is a noun, not the verb form.
• In "We were taught that a gibe...", "gibe" is a noun, not the verb form.

So the sentence where "gibe" is used as the defined verb is "Critics of the mayor often gibe about his less - than - perfect articulation of ideas."

Answer:

Critics of the mayor often gibe about his less-than-perfect articulation of ideas.
