Question

Of the people who die in the United States each year, roughly __________ percent were killed by air pollution.

A) 1%
B) 5%
C) 10%
D) 25%

Answer 1

Roughly 1% of deaths in the U.S. each year are caused by air pollution, with studies showing about 53,000 deaths due to vehicle emissions alone.

Step-by-step explanation:

Of the people who die in the United States each year, roughly 1% were killed by air pollution. This is supported by a 2013 study by MIT indicating that 53,000 early deaths occur per year in the United States alone because of vehicle emissions. While it's difficult to pinpoint the exact percentage as this statistic can fluctuate slightly each year, it's clear that air pollution has a significant impact on mortality rates.

From the various studies and data represented, option A) 1% would be the closest approximation given the figures available though it's important to note that this is an estimate and is reflective of early deaths caused specifically by vehicle emissions.
