With Lieutenant-General Matthew Ridgway assuming the command of the U.S. Eighth Army on 26 December, the PVA and the KPA launched their Third Phase Offensive (also known as the "Chinese New Year's Offensive") on New Year's Eve of 1950. Utilizing night attacks in which UN Command fighting positions were encircled and then assaulted by numerically superior troops who had the element of surprise, the attacks were accompanied by loud trumpets and gongs, which fulfilled the double purpose of facilitating tactical communication and mentally disorienting the enemy. UN forces initially had no familiarity with this tactic, and as a result some soldiers panicked, abandoning their weapons and retreating to the south. The Chinese New Year's Offensive overwhelmed UN forces, allowing the PVA and KPA to conquer Seoul for the second time on 4 January 1951.
Why goals were accomplished the the KPA and PVA's use gongs during these attacks?
****
The answer: facilitating tactical communication and mentally disorienting the enemy

Detroit, like many places in the United States, developed racial conflict and discrimination in the 20th century following rapid demographic changes as hundreds of thousands of new workers were attracted to the industrial city; in a short period it became the 4th-largest city in the nation. The Great Migration brought rural blacks from the South; they were outnumbered by southern whites who also migrated to the city. Immigration brought southern and eastern Europeans of Catholic and Jewish faith; these new groups competed with native-born whites for jobs and housing in the booming city. Detroit was one of the major Midwest cities that was a site for the dramatic urban revival of the Ku Klux Klan beginning in 1915. "By the 1920s the city had become a stronghold of the KKK," whose members opposed Catholic and Jewish immigrants, as well as black Americans. The Black Legion, a secret vigilante group, was active in the Detroit area in the 1930s, when one-third of its estimated 20,000 to 30,000 members in Michigan were based in the city. It was defeated after numerous prosecutions following the kidnapping and murder in 1936 of Charles Poole, a Catholic Works Progress Administration organizer. A total of 49 men of the Black Legion were convicted of numerous crimes, with many sentenced to life in prison for murder.
How many people of The Black Legion were convicted of crimes?
****
The answer: 49

Scientists do not know the exact cause of sexual orientation, but they believe that it is caused by a complex interplay of genetic, hormonal, and environmental influences. They favor biologically-based theories, which point to genetic factors, the early uterine environment, both, or the inclusion of genetic and social factors. There is no substantive evidence which suggests parenting or early childhood experiences play a role when it comes to sexual orientation. Research over several decades has demonstrated that sexual orientation ranges along a continuum, from exclusive attraction to the opposite sex to exclusive attraction to the same sex.
What are the two extremes of the continuum of sexual orientation?
****
The answer:
exclusive attraction to the opposite sex to exclusive attraction to the same sex.
