Context: In an effort to conserve water, Tucson is recharging groundwater supplies by running part of its share of CAP water into various open portions of local rivers to seep into their aquifer. Additional study is scheduled to determine the amount of water that is lost through evaporation from the open areas, especially during the summer. The City of Tucson already provides reclaimed water to its inhabitants, but it is only used for "applications such as irrigation, dust control, and industrial uses." These resources have been in place for more than 27 years, and deliver to over 900 locations.

Please answer this: Extract the answer to the question from the following context. Question: How many people ran for UAR president? Context: During the presidential referendum in Egypt, Nasser was re-elected to a second term as UAR president and took his oath on 25 March 1965. He was the only candidate for the position, with virtually all of his political opponents forbidden by law from running for office, and his fellow party members reduced to mere followers. That same year, Nasser had the Muslim Brotherhood chief ideologue Sayyed Qutb imprisoned. Qutb was charged and found guilty by the court of plotting to assassinate Nasser, and was executed in 1966. Beginning in 1966, as Egypt's economy slowed and government debt became increasingly burdensome, Nasser began to ease state control over the private sector, encouraging state-owned bank loans to private business and introducing incentives to increase exports. During the 60's, the Egyptian economy went from sluggishness to the verge of collapse, the society became less free, and Nasser's appeal waned considerably.
