Jacques-Joseph influenced his brother, Jean-Francois Champollion by encouraging his interest in Middle Eastern languages. This is the right option, as he never had a personal interest on Middle Eastern languages as his brother did, so he never started nor copied it.

The option about mocking his brother's interest makes no sense because he always encouraged him.
