Excellent paper and glad that you were able to introduce the hobby to a few new folks and educate the others on what amateur radio is all about!
The only thing that I feel could have added to the paper was an explanation that EmComm is only one aspect of amateur radio. There are many of us (like myself) that have no interest in EmComm and got into the hobby to communicate with others over the radio and to explore the technical side of RF communications. All too often the EmComm card is played when describing amateur radio. But in the context of your topic of "ham radio helping communities", the EmComm part of the hobby was an excellent point to be made.
Kudos and congrats on getting an A!
