Answer:
Agriculture is the main source of national income for most developing countries. However, for developed countries, agriculture contributes a smaller percentage to their national income. The agricultural sector provides fodder for domestic animals. The cow provides people with milk which is a form of protective food.  The development of agriculture led to the rise of civilizations. People had to stay in one place in order to grow and harvest crops. They also needed buildings in order to store crops. Many civilizations in the Middle East invested in irrigation structures in order to provide for stable water.

Answer:
What caused Schaffer to instruct his assistant to strike Box 342, accidentally sending firefighters to the wrong place was:
B. the dark, hazy night and the tall buildings
Explanation:
The passage establishes the cause-and-effect relationship very clearly. According to the author, Shaffer was trying to determine the exact location of the flames he could see in the distance. However, <u>"This wasn't easy because of the distance and tall buildings between him and the flames. In addition, the moonless sky was made even murkier by the swirling, smoky haze."</u> After offering that explanation, the author says Schaffer instructed his assistant to strike Box 342. What we have here is:
- Cause: the night was dark and hazy; there were also tall buildings making it difficult to determine the location;
- Effect: Schaffer mistook the location of the fire and instructed his assistant to strike Box 342.
