Extract the answer to the question from the following context. Question: Who decides who will run the city? Context: The city is governed pursuant to the Home Rule Charter of the City of Detroit. The city government is run by a mayor and a nine-member city council and clerk elected on an at-large nonpartisan ballot. Since voters approved the city's charter in 1974, Detroit has had a "strong mayoral" system, with the mayor approving departmental appointments. The council approves budgets but the mayor is not obligated to adhere to any earmarking. City ordinances and substantially large contracts must be approved by the council. The Detroit City Code is the codification of Detroit's local ordinances.

Extract the answer to the question from the following context. Question: Which of the following is not a measure of energy: kWh, terajoules, or efficiency? Context: Phase change materials such as paraffin wax and Glauber's salt are another thermal storage media. These materials are inexpensive, readily available, and can deliver domestically useful temperatures (approximately 64 °C or 147 °F). The "Dover House" (in Dover, Massachusetts) was the first to use a Glauber's salt heating system, in 1948. Solar energy can also be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity and can deliver heat at temperatures compatible with conventional power systems. The Solar Two used this method of energy storage, allowing it to store 1.44 terajoules (400,000 kWh) in its 68 cubic metres storage tank with an annual storage efficiency of about 99%.
