Here is the correct order of the aforementioned events:
1) The Radical Republicans introduce the Wade Davis Bill- This bill was introduced to President Abraham Lincoln in 1864.
2) President Abraham Lincoln vetoes the Wade Davis Bill- This means that Lincoln refused to sign this bill into law.
3) John Wilkes Booth assassinated President Abe Lincoln- Lincoln is killed at the Ford Theater on April 14, 1865.
4) The Civil War officially ends- The last Confederate troops finally surrender to the Union on June 2nd of 1865.
5) The Radical Republicans form the Joint Committee on Reconstruction- This committee was established in December of 1865.
The first mask was made in 7000 BC. It was used primarily for rituals and ceremonies and where typically made of leather or wood. Keep in mind, these where the first masks that our modern generation has been able to find and preserve, masks could have been made earlier than this but detirriorated over time.
However, the first modern surgical masks where made in the early 1960s and replaced a more primitive method of cloth masks.

Tulsa's race riots were a large-scale racial conflict between May 31 and June 1, 1921, in which white American population groups attacked the Afro-American community in Tulsa, Oklahoma.
One of its main focuses was the Greenwood district, the most prosperous African-American community in the United States of America, which was completely destroyed.
Contextual background includes the Red Summer of 1919 in the USA, which was characterized by repeated racial conflicts. As an immediate background, on the afternoon of May 30, a man of color, D. Rowland, was reported to the police, accused of attacking a white woman. On the morning of the next day, May 31, D. Rowland was arrested. The repercussion of the case and the existence of previous tensions led to the concentration of black and white armed groups around the place where Rowland was detained, very close to the Greenwood district, throughout the afternoon of the same day and fear about a possible lynching attempt.
I think its b, I could be wrong though.
