Answer
Correct Answer: for the wall below his window
Explanation
Introduction / Context:This item tests correct preposition choice with “fix/attach” plus a surface. English uses “to” (attached to a surface), not “for,” when indicating the object of attachment.
Given Data / Assumptions:
- The ladder is physically affixed to a wall.
- Segment B uses “for the wall …,” which implies purpose rather than attachment.
- Other segments are grammatically fine.
Concept / Approach:Use “fix/attach something to a wall/fence/door.” The preposition “for” marks benefit or purpose (“a ladder for escape”), not physical connection. Hence the correct collocation is “to the wall.”
Step-by-Step Solution:
Identify relationship: physical attachment.Replace preposition: “for” → “to.”Keep the rest: purpose clause “so as to be able to escape …” is fine.Verification / Alternative check:
Corrected: “He fixed a metal ladder to the wall below his window so as to be able to escape if there was a fire.”Why Other Options Are Wrong:
A, C, D are idiomatic; “if there was a fire” is acceptable in a hypothetical past narrative; “if there is a fire” would also be fine in general statements.Common Pitfalls:
Using “for” with verbs that demand “to” for surface attachment; confusing purpose with location.Final Answer:for the wall below his window
