Answer 2

Answer:

"She sat in the library and read books the whole day"

Explanation:

"All that day" is incorrect grammar, unless you are implying for all days except for a certain one.

If you are trying to show someone doing an activity for the whole day/week or the remaining of the day/week, use "the whole day/week.

[If this isn't what you implied at, or the answer you're looking for, please send the whole question to me in the comments]
