Input: Article: Based on the similar shifts underway the nation's economy after 1960, Philadelphia experienced a loss of manufacturing companies and jobs to lower taxed regions of the USA and often overseas. As a result, the economic base of Philadelphia, which had historically been manufacturing, declined significantly. In addition, consolidation in several American industries (retailing, financial services and health care in particular) reduced the number of companies headquartered in Philadelphia. The economic impact of these changes would reduce Philadelphia's tax base and the resources of local government. Philadelphia struggled through a long period of adjustment to these economic changes, coupled with significant demographic change as wealthier residents moved into the nearby suburbs and more immigrants moved into the city. The city in fact approached bankruptcy in the late 1980s. Revitalization began in the 1990s, with gentrification turning around many neighborhoods and reversing its decades-long trend of population loss.

Now answer this question: Where did wealthy residents move?

Output: suburbs

Input: Article: Capital punishment has existed in Tennessee at various times since statehood. Before 1913 the method of execution was hanging. From 1913 to 1915 there was a hiatus on executions but they were reinstated in 1916 when electrocution became the new method. From 1972 to 1978, after the Supreme Court ruled (Furman v. Georgia) capital punishment unconstitutional, there were no further executions. Capital punishment was restarted in 1978, although those prisoners awaiting execution between 1960 and 1978 had their sentences mostly commuted to life in prison. From 1916 to 1960 the state executed 125 inmates. For a variety of reasons there were no further executions until 2000. Since 2000, Tennessee has executed six prisoners and has 73 prisoners on death row (as of April 2015).

Now answer this question: In which year was electrocution introduced as Tennessee's method of execution?

Output:
1916
