Verbal association – choose the item most closely associated with all three actions: Lock, Shut, and Fasten

Introduction / Context:
This verbal association question asks you to pick the single object most commonly and directly associated with the actions listed: lock, shut, and fasten. Such questions test everyday reasoning, vocabulary, and the ability to spot the strongest, most conventional link among options.

Given Data / Assumptions:

• Action words: lock, shut, fasten.
• Options: Window, Door, Iron, Block.
• Select the object that people most typically lock, shut, and fasten in routine contexts.

Concept / Approach:
Map each action to the object that naturally accepts all three actions in common usage. While more than one option may work with one or two verbs, the correct answer should fit all three in the most standard, idiomatic way.

Step-by-Step Solution:

Verification / Alternative check:
Consider home security instructions: “Shut and lock the door, fasten the bolt or chain.” This collocation is extremely common, confirming that “Door” is the most natural match.

Why Other Options Are Wrong:

• Window: You can shut and even lock a window, but “fasten” is less idiomatic compared to a door’s bolt/chain context.
• Iron: An appliance you do not lock or fasten; you may switch it off, not shut or lock.
• Block: A generic item; you do not ordinarily lock or fasten a “block.”

Common Pitfalls:
Assuming multiple objects work because individual verbs fit; the task is to find the single best, everyday fit for all three verbs taken together.

Final Answer:
Door
