Answer:
In simple words, Houston is called energy capital of the world because so much of the energy is produced in the city for all the country. However, due to rising pollution in the city, the Mayor wanted to start a campaign under which the city is to be termed as Energy Conservation Capital of the World.
The meaning of the second term relates to the intention of the mayor in which she wanted to enhance the image of the city along with its standard of living. The conservative word depicts the responsibility of the citizens to use this important resource carefully.
Bleeding Kansas (1855-1861) consisted of millions of dollars in property damage, and dozens dead, due to the onslaught of violence from pro-slavery Border Ruffians who clashed with Free-Staters (jayhawkers) on the matter of slavery.

The right answer is B. The Catholic Monarchs supported Columbus in his project to reach Asia, allowing him to make four trips (in 1492, 1493, 1498 and 1502). In the first one of them he arrived not to India (as he expected) but to the island of Guanahani, in the Bahamas. In addition, they granted him a certain number of privileges, such as the title of Admiral, Governor and Viceroy of the Indies, and a percentage of the riches he found.
