The correct answers are:
b. new interest in mining for gold and silver;
The people in Southeast Asia have kind of stopped with the mining of gold and silver for few centuries, even though until the 14th century there was a lot of mining of this two precious metals. The French changed that, and they encouraged, or rather forced, the mining of the gold and silver again, which brought them a lot of wealth.

The climate in Southeast Asia is very suitable for certain types of crops and trees, so the French used that. They established a lot of large plantations and made the locals work on them, giving them enough payment just to be able to survive.
Answer:
- the first direct detection of gravitational waves came in 2015
- gravitational waves are predicted to travel through space at the speed of light
- the existence of gravitational waves is predicted by Einstein's general theory of relativity
Explanation:
The gravitational waves are waves that are produced by the objects, and depending on the mass of the object they can be stronger or weaker in their influence.
These waves have been in the minds of the scientists for more than a century now, with Einstein predicting them in his theory of relativity. The only problem with these waves was that there was no proof of them. The proof finally came in 2015 when these waves were detected from the first time, with two black holes to be thanked for that as they were the source of them.
These waves are predicted to be able to travel with the speed of light through space when they have small amplitudes.
