Answer 2

Caroline has bought a lot of Christmas presents and her bags are extremely heavy, so she may get a taxi home. The word "may" suggests that there is a possibility that she will choose to get a taxi home. It is not a definite requirement or obligation for her to do so, but rather a potential option.
