Question: How many years had the Northern Ireland Trophy been established when Liang Wenbo reached at least the second round of qualifying in every ranking event? Passage:During the 2006/07 season, Liang reached at least the second round of qualifying in every ranking event.

Question: On what date did Morsi take office? Passage:Following the Egyptian revolution of 2011 as part of the regional Arab Spring protests, Mubarak was ousted and the following year Mohamed Morsi who is backed by the Muslim Brotherhood won Egypt's first democractic elections. In 2013 Morsi was removed from power in a coup led by Abdel Fattah el-Sisi. Sisi has called for religious tolerance and has cracked down and banned the Muslim Brotherhood. He has closed thousands of mosques and has banned 'burkinis' on some beaches. A The Economist report in 2017 stated that Egyptians were turning more secular again, with supporters of sharia law dropping by more than half since 2011, people praying less than before, and gender equality now being widely accepted. The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.

The passage was marked by extremely bad weather and constant squalls and gales. As the fleet sailed out on the Atlantic, passing the Bay of Biscay on their way to England, the weather worsened and storms gradually pushed the ships off their planned course. Finally, on the night of 22 October 1707 Old Style, (2 November 1707 by the modern calendar), the squadron entered the mouth of the English Channel and Shovell's sailing masters believed they were on the last leg of their journey. The fleet was thought to be sailing safely west of Ushant, an island outpost off the coast of Brittany. However, because of a combination of the bad weather and the mariners' inability to accurately calculate their longitude, the fleet was off course and closing in on the Isles of Scilly instead. Before their mistake could be corrected, the fleet struck rocks and four ships were lost:
