Problem: A Federal Trade Commission report issued in 1958 attempted to quantify the effect of antibiotic development on American public health. The report found that over the period 1946-1955, there was a 42% drop in the incidence of diseases for which antibiotics were effective and only a 20% drop in those for which antibiotics were not effective. The report concluded that "it appears that the use of antibiotics, early diagnosis, and other factors have limited the epidemic spread and thus the number of these diseases which have occurred". The study further examined mortality rates for eight common diseases for which antibiotics offered effective therapy (syphilis, tuberculosis, dysentery, scarlet fever, whooping cough, meningococcal infections, and pneumonia), and found a 56% decline over the same period. Notable among these was a 75% decline in deaths due to tuberculosis.
What were eight diseases examined for?
The answer is the following: mortality rates

Problem: Even at high latitudes, glacier formation is not inevitable. Areas of the Arctic, such as Banks Island, and the McMurdo Dry Valleys in Antarctica are considered polar deserts where glaciers cannot form because they receive little snowfall despite the bitter cold. Cold air, unlike warm air, is unable to transport much water vapor. Even during glacial periods of the Quaternary, Manchuria, lowland Siberia, and central and northern Alaska, though extraordinarily cold, had such light snowfall that glaciers could not form.
Which areas in Antartica are considered polar deserts?
The answer is the following: Banks Island, and the McMurdo Dry Valleys

Problem: Beta testing comes after alpha testing and can be considered a form of external user acceptance testing. Versions of the software, known as beta versions, are released to a limited audience outside of the programming team known as beta testers. The software is released to groups of people so that further testing can ensure the product has few faults or bugs. Beta versions can be made available to the open public to increase the feedback field to a maximal number of future users and to deliver value earlier, for an extended or even indefinite period of time (perpetual beta).[citation needed]
What typically comes after the Alpha stage in the development and testing of software?
The answer is the following: Beta testing

Problem: The city was also home to the Royal Naval Engineering College; opened in 1880 in Keyham, it trained engineering students for five years before they completed the remaining two years of the course at Greenwich. The college closed in 1910, but in 1940 a new college opened at Manadon. This was renamed Dockyard Technical College in 1959 before finally closing in 1994; training was transferred to the University of Southampton.
When did the Royal Naval Engineering College shut its doors in Plymouth?
The answer is the following:
1910
