QUES: Violent incidents occurred throughout the Piedmont of the state as white insurgents struggled to maintain white supremacy in the face of social changes after the war and granting of citizenship to freedmen by federal constitutional amendments. After former Confederates were allowed to vote again, election campaigns from 1872 on were marked by violent intimidation of blacks and Republicans by white Democratic paramilitary groups, known as the Red Shirts. Violent incidents took place in Charleston on King Street in September 6 and in nearby Cainhoy on October 15, both in association with political meetings before the 1876 election. The Cainhoy incident was the only one statewide in which more whites were killed than blacks. The Red Shirts were instrumental in suppressing the black Republican vote in some areas in 1876 and narrowly electing Wade Hampton as governor, and taking back control of the state legislature. Another riot occurred in Charleston the day after the election, when a prominent Republican leader was mistakenly reported killed.
What granted Freeman were American citizenship?

ANS: federal constitutional amendments.

QUES: Vacuum is useful in a variety of processes and devices. Its first widespread use was in the incandescent light bulb to protect the filament from chemical degradation. The chemical inertness produced by a vacuum is also useful for electron beam welding, cold welding, vacuum packing and vacuum frying. Ultra-high vacuum is used in the study of atomically clean substrates, as only a very good vacuum preserves atomic-scale clean surfaces for a reasonably long time (on the order of minutes to days). High to ultra-high vacuum removes the obstruction of air, allowing particle beams to deposit or remove materials without contamination. This is the principle behind chemical vapor deposition, physical vapor deposition, and dry etching which are essential to the fabrication of semiconductors and optical coatings, and to surface science. The reduction of convection provides the thermal insulation of thermos bottles. Deep vacuum lowers the boiling point of liquids and promotes low temperature outgassing which is used in freeze drying, adhesive preparation, distillation, metallurgy, and process purging. The electrical properties of vacuum make electron microscopes and vacuum tubes possible, including cathode ray tubes. The elimination of air friction is useful for flywheel energy storage and ultracentrifuges.
What are lightbulbs able to lower the boiling point of?

ANS: unanswerable

QUES: The presence of the University of California, San Diego and other research institutions has helped to fuel biotechnology growth. In 2013, San Diego has the second-largest biotech cluster in the United States, below the Boston area and above the San Francisco Bay Area. There are more than 400 biotechnology companies in the area. In particular, the La Jolla and nearby Sorrento Valley areas are home to offices and research facilities for numerous biotechnology companies. Major biotechnology companies like Illumina and Neurocrine Biosciences are headquartered in San Diego, while many biotech and pharmaceutical companies have offices or research facilities in San Diego. San Diego is also home to more than 140 contract research organizations (CROs) that provide a variety of contract services for pharmaceutical and biotechnology companies.
What institution has contributed to the growth of fuel biotechnology?

ANS: University of California

QUES: On February 14, 2009, The Walt Disney Company debuted "The American Idol Experience" at its Disney's Hollywood Studios theme park at the Walt Disney World Resort in Florida. In this live production, co-produced by 19 Entertainment, park guests chose from a list of songs and auditioned privately for Disney cast members. Those selected then performed on a stage in a 1000-seat theater replicating the Idol set. Three judges, whose mannerisms and style mimicked those of the real Idol judges, critiqued the performances. Audience members then voted for their favorite performer. There were several preliminary-round shows during the day that culminated in a "finals" show in the evening where one of the winners of the previous rounds that day was selected as the overall winner. The winner of the finals show received a "Dream Ticket" that granted them front-of-the-line privileges at any future American Idol audition. The attraction closed on August 30, 2014.
What did the winner win?

ANS:
Dream Ticket
