Question: Agriculture is almost entirely dependent on angiosperms, which provide virtually all plant-based food, and also provide a significant amount of livestock feed. Of all the families of plants, the Poaceae, or grass family (grains), is by far the most important, providing the bulk of all feedstocks (rice, corn — maize, wheat, barley, rye, oats, pearl millet, sugar cane, sorghum). The Fabaceae, or legume family, comes in second place. Also of high importance are the Solanaceae, or nightshade family (potatoes, tomatoes, and peppers, among others), the Cucurbitaceae, or gourd family (also including pumpkins and melons), the Brassicaceae, or mustard plant family (including rapeseed and the innumerable varieties of the cabbage species Brassica oleracea), and the Apiaceae, or parsley family. Many of our fruits come from the Rutaceae, or rue family (including oranges, lemons, grapefruits, etc.), and the Rosaceae, or rose family (including apples, pears, cherries, apricots, plums, etc.).
Try to answer this question if possible: What does the rue family provide that is needed for livestock?
Answer: unanswerable
Question: Between 1042 and 1052 King Edward the Confessor began rebuilding St Peter's Abbey to provide himself with a royal burial church. It was the first church in England built in the Romanesque style. The building was not completed until around 1090 but was consecrated on 28 December 1065, only a week before Edward's death on 5 January 1066. A week later he was buried in the church, and nine years later his wife Edith was buried alongside him. His successor, Harold II, was probably crowned in the abbey, although the first documented coronation is that of William the Conqueror later the same year.
Try to answer this question if possible: What was the date of the Abbey's demolition? 
Answer: unanswerable
Question: Britain also sent troops to protect British business enterprise, harbour rights, and consulate office. This was followed by an eight-year civil war, during which each of the three powers supplied arms, training and in some cases combat troops to the warring Samoan parties. The Samoan crisis came to a critical juncture in March 1889 when all three colonial contenders sent warships into Apia harbour, and a larger-scale war seemed imminent. A massive storm on 15 March 1889 damaged or destroyed the warships, ending the military conflict.
Try to answer this question if possible: When did the crucial climax of the civil war occur?
Answer: March 1889
