Answer 1

The statement that was unknown to scientists during Wegener's time is:

Earth’s crust is made of plates that move.

While Wegener proposed the theory of continental drift and provided evidence for the movement of continents, the understanding of plate tectonics as a mechanism for this movement was not developed until later in the 20th century.
