As the name of the problem states, you need to convert the letters into numbers, then use base three to condense it into a sensible sentence.
To convert each letter into a number, treat space (here a _ means a space) as the first letter, and break every 9 letters. So it's _ABCDEFGH = 0, IJKLMNOPQ = 1, and RSTUVWXYZ = 2. For example, YOU = 212
Then take 3-digit clumps, and convert that into base 10 and its corrosponding letter. 212 = 23, which is W in this case.
Converting the newspaper headlines gives WHAT IS THE LARGEST EVEN PRIME, and the newspaper names give WARRITIRE = 202212120, or TWO, AT_IT_SPARED = 020120210200, or FOUR, and TANK_CURE = 201100220 or SIX. The greatest even prime is two, so WARRITIRE is the name of the newspaper.
