Answer:
a. Slow down and allow him to pass
Explanation:
Since you are driving at the speed limit, you can not speed up to get out of his way. The other driver has more speed limit, and hence, he wants to pass you. If you slow down your speed he can pass and a possible accident could be avoided. Refusal to allow pass results, in most cases, a sense of jealous competition, which also could result in a fatal accident, or blowing to warn also could be irritating for another driver, who could take it as umbrage and will drive even faster in pursuit. A judicious decision is to slow down your car and allow him to pass.

Halloween is said to stem from the Celtic festival of Samhain, which was where people would construct bonfires and dress up in costumes to keep evil spirits away. Pope Gregory III (8th century) made November 1 All Saints Day to memorialize saints and martyrs. The night before All Saints Day was then known as All Hollow's Eve, then Halloween. Over the years, it became a more community-involved event with the addition of trick or treating.
