Masks are a key measure to suppress transmission and save lives. These masks are intended for industrial workers to prevent dust and particles from being breathed in as the valve closes on inhale. However, the valve opens on exhale, making it easier to breathe but also allowing any virus to pass through the valve opening. This makes the mask ineffective at preventing the spread of the virus or any other respiratory virus.

Answer:
While the fight for African American civil rights has been traditionally linked to the 1960s, the discriminatory experiences faced by black soldiers during World War II are often viewed by historians as the civil rights precursor to the 1960s movement. During the war America’s dedication to its democratic ideals was tested, specifically in its treatment of its black soldiers. The hypocrisy of waging a war on fascism abroad, yet failing to provide equal rights back home was not lost. The onset of the war brought into sharp contrast the rights of white and black American citizens. Although free, African Americans had yet to achieve full equality. The discriminatory practices in the military regarding black involvement made this distinction abundantly clear. There were only four
U.S. Army units under which African Americans could serve. Prior to 1940,
thirty thousand blacks had tried to enlist in the Army, but were turned away. In the U.S. Navy, blacks were restricted to roles
as messmen. They were excluded entirely from the Air Corps and the Marines. This level of inequality gave rise to black organizations and leaders who challenged the status quo, demanding greater involvement in the U.S. military and an end to the military’s segregated racial practices.
