Article: With the defeat of the Confederacy in 1865, the Reconstruction Era began. The United States abolished slavery without compensation to slaveholders or reparations to freedmen. A Republican Party coalition of black freedmen, northern carpetbaggers and local scalawags controlled state government for three years. The white conservative Democrats regained control of the state legislature in 1870, in part by Ku Klux Klan violence and terrorism at the polls, to suppress black voting. Republicans were elected to the governorship until 1876, when the Red Shirts, a paramilitary organization that arose in 1874 and was allied with the Democratic Party, helped suppress black voting. More than 150 black Americans were murdered in electoral violence in 1876.

Question: What did the KKK target with violence and terrorism at the polls?
Ans: black voting

Here is a question about this article: The earliest clear evidence of hair or fur is in fossils of Castorocauda, from 164 million years ago in the Middle Jurassic. In the 1950s, it was suggested that the foramina (passages) in the maxillae and premaxillae (bones in the front of the upper jaw) of cynodonts were channels which supplied blood vessels and nerves to vibrissae (whiskers) and so were evidence of hair or fur; it was soon pointed out, however, that foramina do not necessarily show that an animal had vibrissae, as the modern lizard Tupinambis has foramina that are almost identical to those found in the nonmammalian cynodont Thrinaxodon. Popular sources, nevertheless, continue to attribute whiskers to Thrinaxodon.
What is the answer to this question: When was it suggested that foramina premaxillae could contain the first know hairs?
****
So... 1950s

The problem: Answer a question about this article:
The name Montana comes from the Spanish word Montana, meaning "mountain", or more broadly, "mountainous country". Montana del Norte was the name given by early Spanish explorers to the entire mountainous region of the west. The name Montana was added to a bill by the United States House Committee on Territories, which was chaired at the time by Rep. James Ashley of Ohio, for the territory that would become Idaho Territory. The name was successfully changed by Representatives Henry Wilson (Massachusetts) and Benjamin F. Harding (Oregon), who complained that Montana had "no meaning". When Ashley presented a bill to establish a temporary government in 1864 for a new territory to be carved out of Idaho, he again chose Montana Territory. This time Rep. Samuel Cox, also of Ohio, objected to the name. Cox complained that the name was a misnomer given that most of the territory was not mountainous and that a Native American name would be more appropriate than a Spanish one. Other names such as Shoshone were suggested, but it was eventually decided that the Committee on Territories could name it whatever they wanted, so the original name of Montana was adopted.
Where does the state's name mean?
****
The answer: "mountain"

Besides fuels and paving, what accounts for most of the other use of bitumen?
A: Roofing shingles

Question: Read this and answer the question

Possessing a mezzo-soprano vocal range, Madonna has always been self-conscious about her voice, especially in comparison to her vocal idols such as Ella Fitzgerald, Prince, and Chaka Khan. Mark Bego, author of Madonna: Blonde Ambition, called her "the perfect vocalist for lighter-than-air songs", despite not being a "heavyweight talent." According to MSNBC critic Tony Sclafani, "Madonna's vocals are the key to her rock roots. Pop vocalists usually sing songs "straight," but Madonna employs subtext, irony, aggression and all sorts of vocal idiosyncrasies in the ways John Lennon and Bob Dylan did." Madonna used a bright, girlish vocal timbre in her early albums which became passe in her later works. The change was deliberate since she was constantly reminded of how the critics had once labelled her as "Minnie Mouse on helium". During the filming of Evita, Madonna had to take vocal lessons, which increased her range further. Of this experience she commented, "I studied with a vocal coach for Evita and I realized there was a whole piece of my voice I wasn't using. Before, I just believed I had a really limited range and was going to make the most of it."

When did Madonna take voice lessons?
Answer:
filming of Evita
