When you're driving, concentrate __ the road!

When you're driving, concentrate __ the road!

• A. on
• B. in
• C. at
• D. to

Answer: (A)

This item tests which preposition fits with the verb concentrate to show what your attention is directed at. When you’re driving, you need to direct your mental effort toward something specific, and in English the common way to say that is concentrate on something. So the natural phrase is concentrate on the road, meaning you’re paying attention to the road ahead. Using in, at, or to would not express this idea correctly: in would imply being inside something, at isn’t used to indicate what you focus on, and to wouldn’t describe paying attention either.
