Input: Read this: In Europe, rates of tuberculosis began to rise in the early 1600s to a peak level in the 1800s, when it caused nearly 25% of all deaths. By the 1950s, mortality had decreased nearly 90%. Improvements in public health began significantly reducing rates of tuberculosis even before the arrival of streptomycin and other antibiotics, although the disease remained a significant threat to public health such that when the Medical Research Council was formed in Britain in 1913, its initial focus was tuberculosis research.
Question: What year did streptomycin arrive?

Output: unanswerable

Input: Read this: Another potential weapon system for anti-aircraft use is the laser. Although air planners have imagined lasers in combat since the late 1960s, only the most modern laser systems are currently reaching what could be considered "experimental usefulness". In particular the Tactical High Energy Laser can be used in the anti-aircraft and anti-missile role. If current developments continue, some[who?] believe it is reasonable to suggest that lasers will play a major role in air defence starting in the next ten years.
Question: What laser can currently be used in the type of role that was first thought of in the late 1960s?

Output: Tactical High Energy Laser

Input: Read this: Since the beginning of the study of electricity non conductive materials like glass, porcelain, paper and mica have been used as insulators. These materials some decades later were also well-suited for further use as the dielectric for the first capacitors. Paper capacitors made by sandwiching a strip of impregnated paper between strips of metal, and rolling the result into a cylinder were commonly used in the late 19century; their manufacture started in 1876, and they were used from the early 20th century as decoupling capacitors in telecommunications (telephony).
Question: For what use were non conductive materials used in the first capacitors?

Output: as the dielectric

Input: Read this: In May 2013, the club launched a new crest to improve the reproducibility of the design in print and broadcast media, particularly on a small scale. Critics[who?] suggested that it was external pressure from sports manufacturers Nike, Inc. that evoked the redesign as the number of colours has been reduced and the radial effect have been removed, making the kit more cost efficient to reproduce.[citation needed] The redesign was poorly received by supporters, with a poll on an Everton fan site registering a 91% negative response to the crest. A protest petition reached over 22,000 signatures before the club offered an apology and announced a new crest would be created for the 201415 season with an emphasis on fan consultation. Shortly afterwards, the Head of Marketing left the club.
Question: What executive issued the apology for Everton?

Output:
unanswerable
