ANSWERS = [ B - A - A ] 
ROSTER HAS BEEN REORDER
    Good morning/evening, everybody! Thank you for joining us last night.
    We hope you discovered something interesting during the time we spent together on the Insomniac Net last night.
    Thanks to you all for playing along -- it was a lot of FUN for us. Hopefully, you had fun too!
        -- The ever-delightful Shelley [KF7TBA] and just plain old LW [K7LWA] (email K7LWA.INS@gmail.com).

=================
    As many of us learned in school, a Prime Number is a positive integer (i.e., a whole number) greater than one, which is only divided by itself and one.
    Examples of primes are the following: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37,.. etc.
    So, accordingly, how much do you know about the Prime Numbers?
    For tonight's True-or-False ("TorF") questions, please give us your best answer for each of the following 3 TRUE or FALSE questions, by using the (reuseable) answers of "A"=TRUE or "B"=FALSE.
    Good Luck and remember, YOU are always a WINNER with us, regardless of your actual answers!
    OK, Put down your fork, push aside the prime rib, and let's get TorF-ing!
++ "Prime Time" ++
Question #1: If a positive whole number is not a prime number, it is called a "combination" number -- True or False?
        A. True, or
        B. False.
An integer greater than one is prime if its only positive divisors are itself and one (otherwise it is composite).  For example: 15 is composite because it has the two prime divisors 3 and 5.

Question #2Prime Rib is a tender, flavorful roast cut from the center of the rib section of the steer, consisting of a Prime number of ribs -- i.e. 7 ribs (#6 through #12) -- True or False?
        A. True, or
        B. False.
 
 
 
    "The prime rib is a tender, flavorful roast cut from the center of the rib section of the steer.
    To locate the prime rib, start by cutting your favorite steer neatly down the center from head to tail along the spine. Set aside one half for another use. Place your hand on its back and feel your way backwards along its vertebrae until you start feeling ribs. Count backwards to the sixth rib (this is called, appropriately enough "Rib #6"), and cut here.
    Now continue counting back until you get to Rib #12 and cut again. Reserve the head section and the tail section for another use, saving just the ribs you just cut out. Now saw the ribs off at about 13 to 16-inches down their length and set aside the belly section. Take off the hide, and what you're left with is the prime rib.
    It consists of seven full ribs with a large eye of meat running along their back side. This meat is part of the loin muscle of the steer, the exact same muscle that New York strips, rib-eyes, and Delmonicos are cut from. It's also often referred to as a "standing rib roast," because, well, you roast it, it's from the ribs, and it stands up...."

Question #3: As of Jan 7, 2016, the newest record prime number consists of 22,338,618 digits -- True or False?
        A. True, or
        B. False.
New record prime: 274,207,281-1 with 22,338,618 digits by Cooper, Woltman, Kurowski, Blosser & GIMPS (7 Jan 2016).

    ++ QUOTE OF THE DAY ++ -- Leonard Euler (1707 - 1783), a Swiss mathematician

"Mathematicians have tried in vain to this day to discover some order in the sequence of prime numbers, and we have reason to believe that it is a mystery into which the mind will never penetrate."
