Answer:
Heather does not usually turn in her homework on time.
Step-by-step explanation:
This is the statement that best describes what Heather is usually like. In these lines, we learn that Heather forgot her homework at home. However, there are two details that indicate that Heather is not always a responsible student. The first is the fact that Heather said she "finally" did her homework, indicating she does not often do it. The second one is that the teacher asked her "again?" when she stated she did not have it, confirming the fact that Heather does not usually turn in her homework on time.
