Which statement is true of the wave of labor strikes that occurred in \( 1919 ? \) a) Employers used anti-immigrant sentiment to divide workers. b) Walkouts were universally successful across different industries. c) Middle-class opinion strongly supported striking workers. d) Police officers established their right to strike for higher wages and shorter hours. e) The AFL and the IWW continued to oppose each other and organize independently.

The correct answer is (a) Employers used anti-immigrant sentiment to divide workers. Explanation: During the wave of labor strikes in 1919, many strikers were immigrants or radicalized by socialist and anarchist ideas, which made them targets of accusers who portrayed them as un-American or linked them to subversive ideologies. Employers and political leaders exploited these feelings by emphasizing anti-immigrant sentiment, which helped fracture solidarity among workers. This tactic was used to weaken the labor movement by pitting workers against each other based on nationality or political views, thereby undermining the potential for unified action across different groups. The other options are not accurate: • (b) While many walkouts occurred, they were not universally successful across industries. • (c) Middle-class opinion did not universally support the striking workers; in fact, many were wary of the radicalism associated with the strikes. • (d) Police officers did not have a significant documented strike over wages and hours during that period. • (e) Although the AFL and the IWW had differences in organizing methods and ideologies, the statement about them "continuing to oppose each other" does not capture the complexities of their relationship in the context of the 1919 strikes. Thus, option (a) best reflects a true aspect of the labor strike wave of 1919.
