Ehrlich's approach of systematically varying the chemical structure of synthetic compounds and measuring the effects of these changes on biological activity was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and Gerhard Domagk. This work, also based in the testing of compounds available from the German dye industry, led to the development of Prontosil, the first representative of the sulfonamide class of antibiotics. Compared to arsphenamine, the sulfonamides had a broader spectrum of activity and were far less toxic, rendering them useful for infections caused by pathogens such as streptococci. In 1939, Domagk received the Nobel Prize in Medicine for this discovery. Nonetheless, the dramatic decrease in deaths from infectious diseases that occurred prior to World War II was primarily the result of improved public health measures such as clean water and less crowded housing, and the impact of anti-infective drugs and vaccines was significant mainly after World War II.
Streptococci and other pathogens could be treated by what type of antibiotics?
****
The answer: sulfonamides

In September 2010, West wrote a series of apologetic tweets addressed to Swift including "Beyonce didn't need that. MTV didn't need that and Taylor and her family friends and fans definitely didn't want or need that" and concluding with "I'm sorry Taylor." He also revealed he had written a song for Swift and if she did not accept the song, he would perform it himself. However, on November 8, 2010, in an interview with a Minnesota radio station, he seemed to recant his past apologies by attempting to describe the act at the 2009 awards show as "selfless" and downgrade the perception of disrespect it created. In "Famous," a track from his 2016 album The Life of Pablo, West implies that this incident led to Swift's stardom, rapping, "I feel like me and Taylor might still have sex/ Why? I made that bitch famous." After some media backlash about the reference, West posted on Twitter "I did not diss Taylor Swift and I've never dissed her...First thing is I'm an artist and as an artist I will express how I feel with no censorship." He continued by adding that he had asked both Swift and his wife, Kim Kardashian, for permission to publish the line.
When did Kanye West post to Twitter apoloizing to Taylor Swift?

The answer: September 2010

During the Mexican Revolution, Alvaro Obregon invited a group of Canadian German-speaking Mennonites to resettle in Mexico. By the late 1920s, some 7,000 had immigrated to Chihuahua State and Durango State, almost all from Canada, only a few from the U.S. and Russia. Today, Mexico accounts for about 42% of all Mennonites in Latin America. Mennonites in the country stand out because of their light skin, hair, and eyes. They are a largely insular community that speaks a form of German and wear traditional clothing. They own their own businesses in various communities in Chihuahua, and account for about half of the state's farm economy, excelling in cheese production.
Mennonites account for about how much of the state's farm economy?
****
The answer: half

The problem: Answer a question about this article:
Royal assent is sometimes associated with elaborate ceremonies. In the United Kingdom, for instance, the sovereign may appear personally in the House of Lords or may appoint Lords Commissioners, who announce that royal assent has been granted at a ceremony held at the Palace of Westminster. However, royal assent is usually granted less ceremonially by letters patent. In other nations, such as Australia, the governor-general merely signs the bill. In Canada, the governor general may give assent either in person at a ceremony held in the Senate or by a written declaration notifying parliament of his or her agreement to the bill.
With what method is royal assent generally granted?
****
The answer:
letters patent
