Input: Read this: Outstanding debts were also agreed and the company permitted to export 250 tons of saltpetre. Again in 1673, Banks successfully negotiated another contract for 700 tons of saltpetre at 37,000 between the king and the company. So urgent was the need to supply the armed forces in the United Kingdom, America and elsewhere that the authorities sometimes turned a blind eye on the untaxed sales. One governor of the company was even reported as saying in 1864 that he would rather have the saltpetre made than the tax on salt.
Question: Due to agreed debt what 250 tons product was first permitted to be exported by the company after the seven years' war?

Output: saltpetre

Input: Read this: Iran has the second largest proved gas reserves in the world after Russia, with 33.6 trillion cubic metres, and third largest natural gas production in the world after Indonesia, and Russia. It also ranks fourth in oil reserves with an estimated 153,600,000,000 barrels. It is OPEC's 2nd largest oil exporter and is an energy superpower. In 2005, Iran spent US$4 billion on fuel imports, because of contraband and inefficient domestic use. Oil industry output averaged 4 million barrels per day (640,000 m3/d) in 2005, compared with the peak of six million barrels per day reached in 1974. In the early years of the 2000s (decade), industry infrastructure was increasingly inefficient because of technological lags. Few exploratory wells were drilled in 2005.
Question: Where does Iran rank in OPEC's top oil exporting nations?

Output: 2nd largest

Input: Read this: During the ceremony of initiation, the candidate is expected to swear (usually on a volume of sacred text appropriate to his personal religious faith) to fulfil certain obligations as a Mason. In the course of three degrees, new masons will promise to keep the secrets of their degree from lower degrees and outsiders, and to support a fellow Mason in distress (as far as practicality and the law permit). There is instruction as to the duties of a Freemason, but on the whole, Freemasons are left to explore the craft in the manner they find most satisfying. Some will further explore the ritual and symbolism of the craft, others will focus their involvement on the social side of the Lodge, while still others will concentrate on the charitable functions of the lodge.
Question: When does a candidate lose ability to fulfill his obligations as a Mason?

Output: unanswerable
