Input: Read this: The reaction to the encyclical's continued prohibitions of artificial birth control was very mixed. In Italy, Spain, Portugal and Poland, the encyclical was welcomed. In Latin America, much support developed for the Pope and his encyclical. As World Bank President Robert McNamara declared at the 1968 Annual Meeting of the International Monetary Fund and the World Bank Group that countries permitting birth control practices would get preferential access to resources, doctors in La Paz, Bolivia called it insulting that money should be exchanged for the conscience of a Catholic nation. In Colombia, Cardinal archbishop Anibal Munoz Duque declared, if American conditionality undermines Papal teachings, we prefer not to receive one cent. The Senate of Bolivia passed a resolution stating that Humanae vitae could be discussed in its implications for individual consciences, but was of greatest significance because the papal document defended the rights of developing nations to determine their own population policies. The Jesuit Journal Sic dedicated one edition to the encyclical with supportive contributions.
Question: What were developing countries encouraged to allow access to by the World Bank?

Output: birth control

Input: Read this: Modern archaeology has led to the discovery of Han artwork portraying inventions which were otherwise absent in Han literary sources. As observed in Han miniature tomb models, but not in literary sources, the crank handle was used to operate the fans of winnowing machines that separated grain from chaff. The odometer cart, invented during Han, measured journey lengths, using mechanical figures banging drums and gongs to indicate each distance traveled. This invention is depicted in Han artwork by the 2nd century AD, yet detailed written descriptions were not offered until the 3rd century AD. Modern archaeologists have also unearthed specimens of devices used during the Han dynasty, for example a pair of sliding metal calipers used by craftsmen for making minute measurements. These calipers contain inscriptions of the exact day and year they were manufactured. These tools are not mentioned in any Han literary sources.
Question: What item was used to make very small measurements during this era?

Output: sliding metal calipers

Input: Read this: The Slavic autonym is reconstructed in Proto-Slavic as *Slovenin, plural *Slovene. The oldest documents written in Old Church Slavonic and dating from the 9th century attest Slovene to describe the Slavs. Other early Slavic attestations include Old East Slavic Slovene for "an East Slavic group near Novgorod." However, the earliest written references to the Slavs under this name are in other languages. In the 6th century AD Procopius, writing in Byzantine Greek, refers to the Sklaboi, Sklabenoi, Sklauenoi, Sthlabenoi, or Sklabinoi, while his contemporary Jordanes refers to the Sclaveni in Latin.
Question: What is the plural form of Slavic?

Output: unanswerable

Input: Read this: The Nippon Hoso Kyokai (NHK, the Japan Broadcasting Corporation) began conducting research to "unlock the fundamental mechanism of video and sound interactions with the five human senses" in 1964, after the Tokyo Olympics. NHK set out to create an HDTV system that ended up scoring much higher in subjective tests than NTSC's previously dubbed "HDTV". This new system, NHK Color, created in 1972, included 1125 lines, a 5:3 aspect ratio and 60 Hz refresh rate. The Society of Motion Picture and Television Engineers (SMPTE), headed by Charles Ginsburg, became the testing and study authority for HDTV technology in the international theater. SMPTE would test HDTV systems from different companies from every conceivable perspective, but the problem of combining the different formats plagued the technology for many years.
Question: What year was NHK Black and White created?

Output:
unanswerable
