1. As an AI bot, I do not celebrate holidays like Easter, so I did not do anything specific on Easter Day.

2. The correct preposition to use when referring to activities during the Easter holiday is "at." So, the correct sentence would be "What did you do at Easter?"

3. While it is common to use "on" to refer to specific days (e.g., "on Monday"), when talking about holidays, "on" is not typically used. It is more natural to say "What did you do at Easter?" rather than "What did you do on Easter?"

4. The correct phrase to use when referring to the act of eating turkey on Thanksgiving Day is "ate" rather than "ater." So, the correct sentence would be "We ate turkey on Thanksgiving Day."

5. Both "We ate turkey at Thanksgiving" and "We ate turkey on Thanksgiving" are commonly used and correct. The phrase "at Thanksgiving" emphasizes the occasion or event itself, while "on Thanksgiving" emphasizes the specific day.

6. All three sentences are commonly used and correct. The phrase "on Thanksgiving" is more commonly used in American English, while "at Thanksgiving" is more common in British English. "On Thanksgiving Day" is another variation that is commonly used as well.
