Final answer:
Option (2), The statement supported by the chart is that the government supported companies in their efforts to restrict union activity, evident through legislation like the Taft-Hartley Act of 1947.
Step-by-step explanation:
Based on the information provided, the statement that is supported is: The government supported companies in their efforts to restrict union activity. This is evident from the passage depicting the context of actions taken by the U.S. government regarding union activities, such as the passage of the Taft-Hartley Act of 1947 which allowed workers to opt out of unions and made the legal climate less favorable for union creation.
Furthermore, while the National Labor Union did hope to leverage government power to arbitrate disputes, there is no direct information supporting that the NLU won the right to collectively bargain, nor that workers won the right to an eight-hour workday in 1880. Also, the passage does not mention specific achievements by the Molly Maguires.
