Select the best evidence to support the statement "Financial incentives from the federal government are partly responsible for the growth in wind energy in the United States."

Question

From 2008 to 2014, the United States led all other countries in the amount of electricity generated by wind. U.S. wind power totaled nearly 168 million megawatthours during 2013, about three times more than the wind power generated in the United States in 2008.
A major contributor to increasing U.S. wind power in recent years has been the federal production tax credit. The amount of U.S. electricity generated from wind has also increased because of state governments' renewable portfolio standards that require a percentage of their states' electricity supply to come from wind power and other renewable energy sources.

Answer 1

The best evidence to support the statement "Financial incentives from the federal government are partly responsible for the growth in wind energy in the United States" is:

"A major contributor to increasing U.S. wind power in recent years has been the federal production tax credit."

This statement directly links federal financial incentives to the growth of wind energy, providing clear evidence for the claim.
