My mother provides me ______ tupper boxes of food.

• A. With
• B. By
• C. For
• D. In

Answer: (A)

The main idea here is the common pattern with the verb provide: you link the person who receives something to the thing that is given using with. So the sentence means the mother is giving you something, and what she’s giving are the tupper boxes of food. The natural, correct preposition to connect the giver, the recipient, and the item is with, forming provide someone with something. Using other prepositions changes the meaning or doesn’t fit the usual verb pattern: by would refer to how something is done or who carries it out, for would suggest a sense of supporting someone rather than specifying the item given, and in would indicate location, which isn’t appropriate here.
