Correct Answer: C
Explanation:
A schedule of film showings can be constructed from the information given in the first nine statements. Statement 2 establishes the days on which film A is shown. Statement 4 establishes the days on which film E is shown. Statement 5 establishes the days on which film C is shown. We can use this information to construct the following schedule, in which an X indicates a day on which a film is shown.

Next we must determine the days on which film D and B are shown
Statement 3 notes that film D is shown on either Monday or Friday. Statement 9 notes that film D is shown on a day on which film A is not shown. Film A is not shown on Friday and Saturday, as specified in statement 2. Thus, film D must be shown on Friday.
Statement 6 notes that film B is shown on three days in succession between Monday and Friday. Statement 9 notes that Film B is shown on a day on which Film A is not shown. Since Film A is not shown on Friday, then film B must be shown on Friday. Further, since it is shown three days in succession, it must be shown on Wednesday, Thursday, and Friday.
now the schedule of film showings can be completed:
|
Monday |
Tuesday |
Wednesday |
Thursday |
Friday |
Saturday |

Let us now proceed to the explanatory answers by referring to the table above
The schedule reveals that films A, C and E-Part 1 can be viewed on Monday. Thus the professor must view films B, D and E- Part 2 on the second day. The schedule reveals that only Friday offers showings of these three films.
