Input: Read this: Life expectancy at birth is estimated to be 52.2 years in 2012 among the lowest in the world. The AIDS epidemic is a large problem in Namibia. Though its rate of infection is substantially lower than that of its eastern neighbour, Botswana, approximately 13.1% of the adult population is[update] infected with HIV. In 2001, there were an estimated 210,000 people living with HIV/AIDS, and the estimated death toll in 2003 was 16,000. According to the 2011 UNAIDS Report, the epidemic in Namibia "appears to be leveling off." As the HIV/AIDS epidemic has reduced the working-aged population, the number of orphans has increased. It falls to the government to provide education, food, shelter and clothing for these orphans.
Question: What is the age expectancy in Botswana as of 2012?

Output: unanswerable

Input: Read this: In 1997, a year after the divorce, Diana was killed in a car crash in Paris. The Queen was on holiday with her extended family at Balmoral. Diana's two sons by CharlesPrinces William and Harrywanted to attend church and so the Queen and Prince Philip took them that morning. After that single public appearance, for five days the Queen and the Duke shielded their grandsons from the intense press interest by keeping them at Balmoral where they could grieve in private, but the royal family's seclusion and the failure to fly a flag at half-mast over Buckingham Palace caused public dismay. Pressured by the hostile reaction, the Queen agreed to return to London and do a live television broadcast on 5 September, the day before Diana's funeral. In the broadcast, she expressed admiration for Diana and her feelings "as a grandmother" for the two princes. As a result, much of the public hostility evaporated.
Question: In what city is Balmoral?

Output: unanswerable

Input: Read this: The Cork accent, part of the Southwest dialect of Hiberno-English, displays various features which set it apart from other accents in Ireland. Patterns of tone and intonation often rise and fall, with the overall tone tending to be more high-pitched than other Irish accents. English spoken in Cork has a number of dialect words that are peculiar to the city and environs. Like standard Hiberno-English, some of these words originate from the Irish language, but others through other languages Cork's inhabitants encountered at home and abroad. The Cork accent displays varying degrees of rhoticity, usually depending on the social-class of the speaker.
Question: What sets the Cork accent apart from other Irish accents?

Output: Patterns of tone and intonation often rise and fall, with the overall tone tending to be more high-pitched

Input: Read this: The apparently sudden appearance of nearly modern flowers in the fossil record initially posed such a problem for the theory of evolution that it was called an "abominable mystery" by Charles Darwin. However, the fossil record has considerably grown since the time of Darwin, and recently discovered angiosperm fossils such as Archaefructus, along with further discoveries of fossil gymnosperms, suggest how angiosperm characteristics may have been acquired in a series of steps. Several groups of extinct gymnosperms, in particular seed ferns, have been proposed as the ancestors of flowering plants, but there is no continuous fossil evidence showing exactly how flowers evolved. Some older fossils, such as the upper Triassic Sanmiguelia, have been suggested. Based on current evidence, some propose that the ancestors of the angiosperms diverged from an unknown group of gymnosperms in the Triassic period (245202 million years ago). Fossil angiosperm-like pollen from the Middle Triassic (247.2242.0 Ma) suggests an older date for their origin. A close relationship between angiosperms and gnetophytes, proposed on the basis of morphological evidence, has more recently been disputed on the basis of molecular evidence that suggest gnetophytes are instead more closely related to other gymnosperms.[citation needed]
Question: What relationship proposed on the basis of morphological evidence has recently been disputed?

Output:
relationship between angiosperms and gnetophytes
