Input: Consider Input: Question: Which of the construction materials that St Nicholas was constructed with has a higher value on the Mohs scale? Passage:St Nicholas is constructed in flint, with some conglomerate and brick, and has limestone dressings. The roofs are tiled. Its plan consists of a nave, a chancel with a north vestry (previously a porch), and a west tower. The tower is wholly octagonal. In each face of the upper stage of the tower is a lancet, and there is another lancet on the west side at a lower level. The parapet is battlemented. The tower has a west doorway in Norman style, which has possibly been re-set from elsewhere in the church. It has scalloped capitals, and zig-zag decoration on the arch. Inside the upper part of the tower is a 17th-century dovecote lined with brick nesting boxes. On the south side, between the tower and the nave, is a brick stair turret. The nave windows have two lights with Decorated tracery. Between the windows on the south side is another Norman doorway, again with zig-zag decoration. The north and south walls of the chancel have two-light windows with Y-tracery, and three-light windows with Perpendicular tracery. The east window has five lights. The east gable is decorated with grotesque carvings, and above the east window is head-corbel and a blocked niche. The vestry has two-light north and south windows. In the north wall of the nave is an Early English doorway, with dog-tooth ornament. Around the church are stepped buttresses.

Input: Consider Input: 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.
