[EX Q]: Paulo Ribenboim proved in 1991 that the set of these is Diophantine, and in 1912 Edmund Landau proposed four "unattackable problems" dealing with them, none of which have yet been solved. The theorem named for them states that the number of them less than or equal to n is approximately equal to n divided by the natural logarithm of n. The GIMPS project seeks to find examples of the Mersenne type of this number, ordinary examples of which can be found using the sieve of Eratosthenes. For 10 points, identify these numbers whose only two factors are 1 and itself.

[EX Q]: This composer has the cellos play half pizzicato, half arco over a sustained "D-A-C-sharp" drone in the first movement of one piece. The second movement of that piece by this composer begins with a high cello solo and includes a celesta ostinato. He included a "Praludium" marked "Rasch" in his sort-of-neo- baroque Piano Suite. Another piece by this composer includes a "Valse de Chopin" and uses an "E-G-E- flat" motive in a movement subtitled "Passacaglia." He originally used titles like "The Obbligato Recitative" and "Chord Colours" for his Five Orchestral Pieces, in which he made the first major use of Klangfarbenmelodie. Another piece by this composer uses a different combination of piano, flute, clarinet, violin, and cello in each movement and is a setting "three times seven poems" by Albert Giraud using sprechstimme. For 10 points, name this Second Viennese School composer who innovated atonality with pieces like his Three Piano Pieces, Opus 11, and Pierrot Lunaire.
