The customer smashed his fist dow . . . . . . . . the table. A. on B. against C. in D. at

The correct answer is: B. against

The word “against” is used to indicate that the customer’s fist made contact with the table in a forceful manner. The other options are not as accurate because they do not convey the same sense of force.

• On suggests that the customer’s fist simply rested on the table.
• In suggests that the customer’s fist penetrated the table.
• At suggests that the customer’s fist was aimed at the table, but did not make contact.
