Problem: Detroit:

Due to industrial restructuring and loss of jobs in the auto industry, Detroit lost considerable population from the late 20th century to present. Between 2000 and 2010 the city's population fell by 25 percent, changing its ranking from the nation's 10th-largest city to 18th. In 2010, the city had a population of 713,777, more than a 60 percent drop from a peak population of over 1.8 million at the 1950 census. This resulted from suburbanization, industrial restructuring, and the decline of Detroit's auto industry. Following the shift of population and jobs to its suburbs or other states or nations, the city has focused on becoming the metropolitan region's employment and economic center. Downtown Detroit has held an increased role as an entertainment destination in the 21st century, with the restoration of several historic theatres, several new sports stadiums, and a riverfront revitalization project. More recently, the population of Downtown Detroit, Midtown Detroit, and a handful of other neighborhoods has increased. Many other neighborhoods remain distressed, with extensive abandonment of properties.

The decline of what industry has hurt Detroit?
---
A: auto

Context and question: On 26 July 1956, Nasser gave a speech in Alexandria announcing the nationalization of the Suez Canal Company as a means to fund the Aswan Dam project in light of the British–American withdrawal. In the speech, he denounced British imperialism in Egypt and British control over the canal company's profits, and upheld that the Egyptian people had a right to sovereignty over the waterway, especially since "120,000 Egyptians had died (sic)" building it. The motion was technically in breach of the international agreement he had signed with the UK on 19 October 1954, although he ensured that all existing stockholders would be paid off.
Who did Nasser claim would still be paid despite nationalization of the canal?
Answer: existing stockholders


Question: Asphalt/bitumen is similar to the organic matter in carbonaceous meteorites. However, detailed studies have shown these materials to be distinct. The vast Alberta bitumen resources are believed to have started out as living material from marine plants and animals, mainly algae, that died millions of years ago when an ancient ocean covered Alberta. They were covered by mud, buried deeply over the eons, and gently cooked into oil by geothermal heat at a temperature of 50 to 150 °C (120 to 300 °F). Due to pressure from the rising of the Rocky Mountains in southwestern Alberta, 80 to 55 million years ago, the oil was driven northeast hundreds of kilometres into underground sand deposits left behind by ancient river beds and ocean beaches, thus forming the oil sands.
Is there an answer to this question: What temperatures did the organic deposits need to form bitumen over the eons?

Answer: 50 to 150 °C


Question: Lewis Latimer, employed at the time by Edison, developed an improved method of heat-treating carbon filaments which reduced breakage and allowed them to be molded into novel shapes, such as the characteristic "M" shape of Maxim filaments. On 17 January 1882, Latimer received a patent for the "Process of Manufacturing Carbons", an improved method for the production of light bulb filaments, which was purchased by the United States Electric Light Company. Latimer patented other improvements such as a better way of attaching filaments to their wire supports.
Is there an answer to this question: What was not an improved method for production of a light bulb?
