presentation (repeated); the acceleration of surface rhythms might suggest continuation function; but the passage is better understood as a variation on the preceding presentation
continuation becomes cadential
dominant
closing section; it is made up of a 4-m. codetta, which is repeated (mm. 99–102) and whose last half is fragmented (mm. 103–05)
no; the harmonic progression V – I is prolongational, not cadential; mm. 103–05 is a codetta, not a cadence
