The Correct Answer and Explanation is:

Correct Answer:
Wednesday, September 18, 2001 and Wednesday, September 18, 2001

Explanation

To identify the identical pair of dates, we must look carefully at each pair, comparing their content (month, day, and year) and formatting.

1. Wednesday, September 18, 2001 vs. Wednesday, September 18, 2001
   These two entries are exactly the same in every way: the weekday (“Wednesday”), the month (“September”), the day (“18”), and the year (“2001”) are all identical. The punctuation and spacing are also consistent. Thus, this pair is truly identical.
2. Tuesday, October 2nd vs. Tuesday. October 2nd
   While these appear similar, they are not identical. The first uses a comma after “Tuesday,” while the second uses a period. Punctuation differences make them non-identical even if the date they reference is the same.
3. 12-01-2011 vs. 12-1-2011
   Though these may refer to the same date (depending on regional formatting), they are not written identically. One uses two digits for the day and month, the other uses one digit for the day. Therefore, they are not identical.
4. January 21st, 2011 vs. January 21, 2011
   The first includes the ordinal “st” after the day (“21st”), while the second simply writes “21.” Despite referencing the same calendar date, the formats differ slightly, making them non-identical.

In contrast, Wednesday, September 18, 2001 appears twice with identical formatting, spelling, punctuation, and structure. In tasks that ask for identical entries, attention to even small typographical elements like periods, commas, and ordinals (“st”, “nd”, etc.) is crucial. Identical does not mean the same date in meaning—it means an exact match in how it’s written. Thus, the correct and only fully identical pair is the Wednesday, September 18, 2001 entriesCorrect Answer:
