Four librarians—Amos, Beth, Clara, and David—each work on a single different day from Monday to Thursday. Clara works the day immediately after Beth. David works on Thursday. Amos works on a day prior to Beth. On which day does Beth work?
Tuesday
David works Thursday. Clara immediately follows Beth, so Beth and Clara must take two consecutive days out of Monday, Tuesday, and Wednesday. The only consecutive pair is Tuesday and Wednesday (Beth on Tuesday, Clara on Wednesday), leaving Monday for Amos.
