Question: The metal's distinctive natural green patina has long been coveted by architects and designers. The final patina is a particularly durable layer that is highly resistant to atmospheric corrosion, thereby protecting the underlying metal against further weathering. It can be a mixture of carbonate and sulfate compounds in various amounts, depending upon environmental conditions such as sulfur-containing acid rain. Architectural copper and its alloys can also be 'finished' to embark a particular look, feel, and/or color. Finishes include mechanical surface treatments, chemical coloring, and coatings.
Try to answer this question if possible: What property does the final patina on copper avoid?

Question: Most food in Alaska is transported into the state from "Outside", and shipping costs make food in the cities relatively expensive. In rural areas, subsistence hunting and gathering is an essential activity because imported food is prohibitively expensive. Though most small towns and villages in Alaska lie along the coastline, the cost of importing food to remote villages can be high, because of the terrain and difficult road conditions, which change dramatically, due to varying climate and precipitation changes. The cost of transport can reach as high as 50 per pound ($1.10/kg) or more in some remote areas, during the most difficult times, if these locations can be reached at all during such inclement weather and terrain conditions. The cost of delivering a 1 US gallon (3.8 L) of milk is about $3.50 in many villages where per capita income can be $20,000 or less. Fuel cost per gallon is routinely 2030 higher than the continental United States average, with only Hawaii having higher prices.

Answer: 50 per pound ($1.10/kg)
Question: The Quran consists of 114 chapters of varying lengths, each known as a sura. Suras are classified as Meccan or Medinan, depending on whether the verses were revealed before or after the migration of Muhammad to the city of Medina. However, a sura classified as Medinan may contain Meccan verses in it and vice versa. Sura titles are derived from a name or quality discussed in the text, or from the first letters or words of the sura. Suras are arranged roughly in order of decreasing size. The sura arrangement is thus not connected to the sequence of revelation. Each sura except the ninth starts with the Bismillah ( ), an Arabic phrase meaning "In the name of God". There are, however, still 114 occurrences of the Bismillah in the Quran, due to its presence in Quran 27:30 as the opening of Solomon's letter to the Queen of Sheba.
Try to answer this question if possible: What two city-related categories multiply the Quran's suras?

Question: After the U.S. accused Libya of orchestrating the 1986 Berlin discotheque bombing, in which two American soldiers died, Reagan decided to retaliate militarily. The Central Intelligence Agency were critical of the move, believing that Syria were a greater threat and that an attack would strengthen Gaddafi's reputation; however Libya was recognised as a "soft target." Reagan was supported by the U.K. but opposed by other European allies, who argued that it would contravene international law. In Operation El Dorado Canyon, orchestrated on 15 April 1986, U.S. military planes launched a series of air-strikes on Libya, bombing military installations in various parts of the country, killing around 100 Libyans, including several civilians. One of the targets had been Gaddafi's home. Himself unharmed, two of Gaddafi's sons were injured, and he claimed that his four-year-old adopted daughter Hanna was killed, although her existence has since been questioned. In the immediate aftermath, Gaddafi retreated to the desert to meditate, while there were sporadic clashes between Gaddafists and army officers who wanted to overthrow the government. Although the U.S. was condemned internationally, Reagan received a popularity boost at home. Publicly lambasting U.S. imperialism, Gaddafi's reputation as an anti-imperialist was strengthened both domestically and across the Arab world, and in June 1986, he ordered the names of the month to be changed in Libya.
