We can immediately reject option D - while Spanish is an Indo-European language, Quechua is an indigenous language of the Americas.
The Spanish conquerors did not care much about the indigenous population - except if they could covert them, which would make them be seen as defenders of the Christian faith and win them favours with the Pope.
So they would not teach the indigenous population in secular schools, they would however, try to teach them religion. The correct answer is A - The Catholic clergy believed that Christianity would be adopted faster if translated into an indigenous language.
Divergent boundaries move oceanic plates (plates found in the ocean) away from each other, making magma seep in to fill those cracks, thus spreading the sea floor.

Answer:
Surface waves have a longer duration and higher amplitude than body waves.
Explanation:
The stark difference between an earthquake body and surface waves is such that they have longer duration and a higher amplitude compared to body waves.
There are two categories of seismic waves that usually accompanies an earthquake:
- body waves are faster and perpetuate in the subsurface. They reach the seismic station first and are discovered faster.
- surface waves arrives later and they cause the damage produced by most earthquake waves. They perpetuate on the surface.
- surface waves are the love and Rayleigh waves
- body waves are the primary and secondary waves.
