Answer:
Howie should have written a subject like this: HOWIE'S HOMEWORK
Step-by-step explanation:
Writing a subject name in your subject line while sending any form of electronic message via computer or mobile phone is very important because it helps the receiver to have a summarized view of what will be contained in the message. If Howie had a very good subject for his Email like HOWIE'S HOMEWORK attached to his email, this would have helped the instructor to notice his Email quickly owing to the fact that he has spoken with Howie about the home work submission via email, seeing his name and homework attached to it in his inbox we prompt him to open-up the email.
And this would have led to having having a score/point for the day's assignment.
