The correct answer is C. if you do not know the note you took, you can always ask your teacher what exactly it could mean. Especially if it's a date
If Sarah doesn't understand why she wrote down "1985" in her notes, she should ask her teacher what the date may stand for.
The correct answer is c (the second one in chronological order).
Sarah could also create an explanation based on the information that she does know, but there's a chance that she makes a mistake. The most accurate way of knowing what that date means is to go straight to the source: her teacher. She/He will tell Sarah what happened in that date and she will be able to trust the data is correct.
