Which text best completes the sentence?
You should plant crocus bulbs three inches below the surface of the soil and dig ______ holes for daffodil bulbs.
1)the deepest
2)deeper
3) more deeper
This is because the sentence is using the word deeper to make a direct comparison between the depth of the crocus to the daffodil. And so it can not be 3 as that is not grammatically correct.
