A dawn to dusk two-day workshop was held _____ Monday and Tuesday, May 4 and 5, 2011. A) between B) on C) at D) from

Answer 1

(c) on.

We would use "between" if there were three or more days, e.g. "between Monday and Wednesday" or "between Monday and Thursday".

We would use "from" with "to", e.g., "from Monday to Wednesday", typically again only if there were three or more days.

We would use "at" for locations or for times of the day.
