Who is mr d and why is he in the summer camp percy jackson

He’s the god of wine Dionysius but he was “exiled” to Camp Halfblood for bad behavior (if I recall correctly)

"Mr. D" is Dionysus, most commonly known as the God of Wine. He was placed as director in Camp Half-Blood as punishment by his father Zeus for chasing after an off-limits nymph, or to put it simply, for bad behavior. Correct me if I'm wrong!

the incorrect statement about jews is: d. jews began migrating to germany after the end of world war i. jews migrated throughout the world across many centuries, and that was also the case with germany, the migration began before the end of world war i, but there was an emigration wave before the start of the world war ii.
