Explanation:

Considering statement 1:
The last day of the month is a Wednesday. However, we do not know the number of days in the month,
so we cannot find the day on the 14th of that month.
Hence, statement 1 alone is not sufficient to answer the question.
Considering statement 2:
17th of that month is the third Saturday. So, 14th of that month must be a Wednesday.
Hence, statement 2 alone is sufficient to answer the question.
