The Awards Committee panel member posts a question in the Education and Training section, once per week at a random time on a random day.
All parts of the question must be answered in one post. You may not post more than once. The first(and only) post counts, get it right the first time.
Do not edit your posts as the Awards Committee can see that time stamp in the edited post…it just makes our sorting it out more cumbersome.
First correct answer (as judged by the question poster, and the award committee) wins. The lucky winner gets one case of “Now that you’ve had a Home Inspection Books” shipped to you. Courtesy of Nick G. Your prize will be shipped to the address on file.
