Example 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.

The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.

The brigadier was commanding from a scout car whose radio broke down. Kershaw, despite heavy machine gun and artillery fire, repeatedly ran from his tank, to the scout car, and back, to take the brigadier's orders, which he then relayed over the tank's radio.

Kershaw volunteered to man his tank, which had been disabled, to bring additional fire to bear on the advancing forces; despite its vulnerability to artillery fire as it was in full view on a road.
