wate nvm i think u mite be rong... idrk y r u even askin me g0 tel ur teecher

1. yes

2. no, could've also finished it

1. Yes, in the sentence "I read the book in five days," it implies that the person finished reading the book from the first page to the last page within a time period of five days. The phrase "in five days" indicates that the entire book was read within that time frame.

2. On the other hand, the sentence "I read the book for five days" suggests that the person spent a duration of five days reading the book, but it does not necessarily imply that they completed reading the entire book. It means that they dedicated five days for reading, but whether they finished the book or not is unclear.
