“Thrust” is the characteristic action with a “Spear.” Choose the option that preserves a specific action → weapon relation.

Introduction / Context:
Action–instrument analogies connect a characteristic action to the implement designed for that action. “Thrust” is the quintessential spear action. In fencing, the épee is a thrusting weapon; the sport’s action “to fence” with an epee is dominated by thrusts rather than cuts.

Given Data / Assumptions:

• Spear → thrusting action.
• Epee (in fencing) → primarily thrusting.

Concept / Approach:
“Fence : Epee” best mirrors action → weapon. Other options misalign the relation: “Scabbard : Sword” is container → contained; “Mangle : Iron” mismatches a verb and an appliance not analogous to the spear’s action; “Bow : Arrow” is launcher → projectile, not action → weapon.

Step-by-Step Solution:
1) Identify required mapping: characteristic action → proper weapon.2) Choose the fencing weapon used for thrusting (epee).3) Select “Fence : Epee.”

Verification / Alternative check:
In sport fencing, foil and epee score with thrusts; sabre adds cuts. The epee is a pure thrusting weapon, aligning tightly with “thrust : spear.”

Why Other Options Are Wrong:

• Scabbard : Sword: Not action → weapon.
• Mangle : Iron: Not a standard action–instrument pairing.
• Bow : Arrow: Implements a launch, not a thrust action relation.

Common Pitfalls:
Confusing container, projectile, or appliance relations with action–weapon mappings.

Final Answer:
Fence : Epee
