Answer:
B. Would help
Step-by-step explanation:
In the first part of the sentence the word “planted” shows up. This gives us context clues that the sentence is written in past tense.
The second part of the sentence it has the word “hoping” as past tense verb.
This means that “‘would help’ with food” is the best option. Not only does it flow nicely but it also represents that the grandfather was thinking of the future.
“was helping”/no change necessary doesnt work because it means that the garden had already been planted and had already been helping.
“Will help” doesn’t work because the tense is not correct. This is because “will” is current when we are talking about the past.
and finally, “helped” is not correct because this would mean that the garden had already helped. This isn’t possible because it takes time for things to grow.
All of this said, we can determine that the answer is B. Would help.
