Answer:

There are several evidence that show rise in global temperature.

Explanation:

Thermometer readings

Ongoing temperature recordings using thermometers are showing a clear warming of the earth's temperature over past few decades.

Glacier retreat

Over the past 50 to 100 years, photographic evidence has shown that the world's glaciers have been melting, which has caused them to retreat. The increase in global temperatures is causing glaciers to disappear and is increasing the melting of sea ice in artic.

Ice cores

scientists often use ice cores to detect changes in temperatures. When snow falls it traps air into the ice. When scientists take a sample of ice it reveals the atmospheric gas concentrations at the time the snow fell. This is used to calculate temperature of each year.

Early spring and Rising sea levels are also the evidence of global warming.

Answer:

$\boxed {\boxed {\sf D. \ Build \ the \ nation's \ gold \ and \ silver \ reserves \ by \ exporting \ more \ goods \ than \ it \ imported}}$

Explanation:

Mercantilism is an economic policy that thrived beginning in the 1500s. It was one of the driving forces behind colonization and imperialism.

A country wanted to gain as much wealth as possible. One way to accomplish this goal was to implant a favorable balance of trade. This meant the country exported more goods (sold) than it imported (bought). Essentially, the wealth flowing into the nation was greater than the money leaving.

The countries needed a way to create this balance. So, they began to colonize. Colonies were incredibly valuable because they had natural resources. The mother country extracted the resources from the colony, produced goods in the country, and then sold them back to the colony. This practice maximized their wealth, gold, silver, and power.

The best answer choice must be D. Build the nation's gold and silver reserves by exporting more goods than it imported.
