Given data

• Prompt: ‘‘To slap with a flat object’’ → find the most precise verb.
• Options: Swat, Chop, Hew, Gnaw.

Concept / Approach
Swat means to strike or slap sharply with a flat object (e.g., a flyswatter or open palm). The other verbs do not involve a flat slapping action.

Step-by-step elimination
Swat — sharp, flat-surface strike; matches ‘‘slap’’. ✅Chop — cut with a quick downward blow, typically with an edge (axe/hand edge). ❌Hew — to chop or cut, often shaping with blows of an axe; not a slap. ❌Gnaw — bite persistently; no slapping. ❌

Verification / Usage
‘‘He swatted the mosquito with a magazine.’’ → flat-object strike.

Common pitfalls

• Confusing any quick strike with slapping; slapping specifically implies a flat surface.

Final Answer
Swat
