The statement that is not true of Bach’s Brandenburg Concerto No. 5 in D Major, BWV 1050 is:
It includes dynamics that slowly change over time.
While Baroque music, including Bach's works, does include dynamic contrasts, the specific use of gradually changing dynamics (such as crescendos and decrescendos) in the way that later music does was not typical of this period. The other statements about the work are accurate.
