Answer: C) almost doubled
Explanation:
The unemployment rate does not include those who were so discouraged from looking for work that they stopped and those who work part-time jobs even though they don't get much pay.
The Bureau of Labor Statistics estimated that in April 2017, if these two groups of people had in fact being included in unemployment statistics, the rate would have almost doubled. This shows that too many people were either not working in the U.S. at that time or they were not working fully.
