4.        ** License Exam Questions of the week

One question is drawn from each of the three question pools. Steve, AE8AT,
is providing these questions.  Thanks Steve

 

Answers are at the end of this email.

 

We received a question regarding the strange mix of letters and numbers that
begin each question.  Every exam question has a unique combination of
letter-number-letter-number.  The first letter is a T, G, or E to identify
the question pool: Technician, General, or Extra.  Next is a single number
representing the category, for example, category zero is safety in all three
exam pools.  The first letter-number pair is called the "sub-element".   The
second letter is a "group" containing related questions.  Example,
sub-element G8 is Signals and Emissions, with group C of that sub-element
being Digital Emission Modes.  The questions are numbered sequentially:
G8C01, G8C02, and so forth always with a 2-digit number at the end.  The
question identity is included in case of a typo or some "help" from
autocorrect obscures either the question or the answer.  

 

The quiz this week is inspired by a rental house the family used over the
Thanksgiving holiday for a more homelike feeling than staying in hotels.
The morning of Thanksgiving we discovered that the "furnished" house had one
single coffee filter.  This week's quiz is on filters!
