Answer:
A. Global Positioning System (GPS)
Explanation:
The Global Positioning System (GPS) is the most accurate way to find your exact location, virtually anywhere on the planet, thanks for a large network of satellites orbiting the planet and providing location information. That system is also complemented by the cellular towers if you're using a cell phone.
Aerial photography is great, but it will not tell you where you are.
Remote sensing is to gather information from a distance, not relevant to the question here.
The Geographic Information Systems are information systems to give information about the land matched with precise GPS information, used in mining for example, but it's not able to tell you where you are, it's to tell where a gold deposit is however.
A. Human Activity
"According to the National Climate Assessment, human influences are the number one cause of global warming, especially the carbon pollution we cause by burning fossil fuels and the pollution-capturing we prevent by destroying forests. The carbon dioxide, methane, soot, and other pollutants we release into the atmosphere act like a blanket, trapping the sun's heat and causing the planet to warm. Evidence shows that 2000 to 2009 was hotter than any other decade in at least the past 1,300 years<span>. This warming is altering the earth's climate system, including its land, atmosphere, oceans, and ice, in far-reaching ways."
