The Chicago Transit Authority's elevated train running through Evanston is called the Purple Line, taking its name from Northwestern's school color. The Foster and Davis stations are within walking distance of the southern end of the campus, while the Noyes station is close to the northern end of the campus. The Central station is close to Ryan Field, Northwestern's football stadium. The Evanston Davis Street Metra station serves the Northwestern campus in downtown Evanston and the Evanston Central Street Metra station is near Ryan Field. Pace Suburban Bus Service and the CTA have several bus routes that run through or near the Evanston campus.
Which train station is close to the northern end of campus?
****
The answer: Noyes


The problem: Answer a question about this article:
The plan stated that the following numbers of species of different groups had been recorded from Egypt: algae (1483 species), animals (about 15,000 species of which more than 10,000 were insects), fungi (more than 627 species), monera (319 species), plants (2426 species), protozoans (371 species). For some major groups, for example lichen-forming fungi and nematode worms, the number was not known. Apart from small and well-studied groups like amphibians, birds, fish, mammals and reptiles, the many of those numbers are likely to increase as further species are recorded from Egypt. For the fungi, including lichen-forming species, for example, subsequent work has shown that over 2200 species have been recorded from Egypt, and the final figure of all fungi actually occurring in the country is expected to be much higher.
How many species of plants were recorded in Egypt?
****
The answer: 2426


The problem: Answer a question about this article:
The bacillus causing tuberculosis, M. tuberculosis, was identified and described on 24 March 1882 by Robert Koch. He received the Nobel Prize in physiology or medicine in 1905 for this discovery. Koch did not believe the bovine (cattle) and human tuberculosis diseases were similar, which delayed the recognition of infected milk as a source of infection. Later, the risk of transmission from this source was dramatically reduced by the invention of the pasteurization process. Koch announced a glycerine extract of the tubercle bacilli as a "remedy" for tuberculosis in 1890, calling it "tuberculin". While it was not effective, it was later successfully adapted as a screening test for the presence of pre-symptomatic tuberculosis. The World Tuberculosis Day was established on 24 March for this reason.
What year was Koch awarded a Nobel Prize?
****
The answer: 1905


The problem: Answer a question about this article:
In 1654, Otto von Guericke invented the first vacuum pump and conducted his famous Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been partially evacuated. Robert Boyle improved Guericke's design and with the help of Robert Hooke further developed vacuum pump technology. Thereafter, research into the partial vacuum lapsed until 1850 when August Toepler invented the Toepler Pump and Heinrich Geissler invented the mercury displacement pump in 1855, achieving a partial vacuum of about 10 Pa (0.1 Torr). A number of electrical properties become observable at this vacuum level, which renewed interest in further research.
What was the vacuum created by the mercury displacement pump?
****
The answer:
partial vacuum of about 10 Pa (0.1 Torr).
