Answer to Question 1

Answer: The map on the left shows two different apparent polar wandering paths, and so that must be the fixed continent model: If the continents aren't allowed to move, then the planet must have had two North Poles in the past, and they just recently converged. On the other hand, the map on the right shows that if the continents are allowed to shift position over time, then the two apparent polar wandering paths can be reconciled with one another to produce a single, coherent pole.

Answer to Question 2

D
