I want to know the answer to the following question:
What was the number of people executed in 2015?
All the background I'm provided with is that "Texas has accounted for over one-third of modern executions (although only two death sentences were imposed in Texas during 2015, with the courts preferring to issue sentences of life without parole instead) and over four times as many as Oklahoma, the state with the second-highest number.". Is that enough to answer the question?
