Here’s how the Verb Tense and Meaning Technique works:
If your question says something like:
What is most likely to happen next?
- The boy will call his mom.
- The boy remains calm.
- His sister called him.
- His sister would bother him.
You can eliminate (or slash) 3 and 4 because called is in the past tense (an action that is finished) and would bother (with the use of would) talks about an ongoing action that happened in the past over a period of time.
You can further eliminate #2 because it is in the present tense, and doesn’t answer the question which is clearly referring to a future action.
