One of my hobbies is Ham Radio (Amateur Radio). There are three classes of licences: Technician, General, and Amateur Extra. You must pass a multiple choice exam to be granted one of the classes. The exam covers 35(Technician and General) or 50(Amateur Extra) topics. One question is taken from the question pool for each topic.
While taking practice exams, I noticed that there were some words that would only appear in the correct answer. I decided to do an analysis of the question pools. I took each question pool and found all words that appeared once in the correct answer.
Here are the question numbers and the words that are unique in each question pool:
T1A01 advancing, skills, technical, phases, art
