Sentence Completion (Questions 21–28)
linker logic, tense agreement and sentence structure
The Method
- Look at the linker in the given half (although, because, unless, so … that). It tells you the logical relation the other half must have.
- Check the tense: If + past perfect → would have + V3; By the time + past → past perfect; since + past → present perfect.
- Eliminate structurally: if the given half already has a linker, the answer cannot start with another linker (Although …, but … is wrong).
- Pronouns must match: The students …, they / The company …, it.
Linker → What the Other Half Must Show
