Question

complete the analogy.
blacksmith is to anvil as mechanic is to
car
wrench
shop

Explanation:

A blacksmith uses an anvil as a tool for their work. A mechanic uses a wrench as a tool for repairing cars. A car is the object being worked on, not a tool, and a shop is the location, not a tool. So the relationship is worker - tool, so mechanic relates to wrench as blacksmith relates to anvil.

wrench
