39. If an oncoming vehicle has its high-beam headlights on, A. slow down and glance down at the right edge of the road as a guide for your lane position. B. honk your horn. C. stare directly into the oncoming lights. D. turn on your high-beam headlights.

The correct answer is A. Slow down and glance down at the right edge of the road as a guide for your lane position.

Explanation:

High-beam headlights on other cars can cause you are temporarily blinded, which reduces your abilities to drive properly and increases the chances of accidents. Due to this, if there is an oncoming vehicle with high-beam headlights on the general recommendation is to avoid staring directly and instead look toward the right, while still being aware of the lane position. In this way, your vehicle is in the lane and you avoid accidents while the other car passes. Besides this, it is a good idea to slow down just to reduce any risk as you are not looking directly at the position of the other car. Thus, option A describes the correct reaction in this situation.

expository writing is one of the most common types of writing.
