Description acceptable. The documentary They Planted a Stone records an instance of this action being taken at Sennar (“suh-NAR”) as part of the Gezira (“juh-ZEE-ra”) Scheme. Ibn al-Qifṭi claimed that Ibn al-Haytham’s failure to perform this action led him to feign madness in order to avoid being punished by al-Ḥākim (“el HAH-keem”). One instance of this action sparked a UNESCO campaign that led the Metropolitan (15[1])Museum of Art to build the Sackler (-5[1])Wing to house the (*) Temple (10[1])of Dendur. The Soviet Union funded that example of this action which led to the relocation of Abu (10[1])Simbel. (10[3])One performance of this action (10[1])created a “High” structure at Aswan, (10[1])while another was named for a “Grand Ethiopian Renaissance.” (10[1])For 10 points, name this action which created Lake Nasser and controlled Egyptian seasonal flooding. ■END■
