Problem: Copper:

Copper has been used since ancient times as a durable, corrosion resistant, and weatherproof architectural material. Roofs, flashings, rain gutters, downspouts, domes, spires, vaults, and doors have been made from copper for hundreds or thousands of years. Copper's architectural use has been expanded in modern times to include interior and exterior wall cladding, building expansion joints, radio frequency shielding, and antimicrobial indoor products, such as attractive handrails, bathroom fixtures, and counter tops. Some of copper's other important benefits as an architectural material include its low thermal movement, light weight, lightning protection, and its recyclability.

Problem: Elizabeth II:

In 2002, Elizabeth marked her Golden Jubilee. Her sister and mother died in February and March respectively, and the media speculated whether the Jubilee would be a success or a failure. She again undertook an extensive tour of her realms, which began in Jamaica in February, where she called the farewell banquet "memorable" after a power cut plunged the King's House, the official residence of the governor-general, into darkness. As in 1977, there were street parties and commemorative events, and monuments were named to honour the occasion. A million people attended each day of the three-day main Jubilee celebration in London, and the enthusiasm shown by the public for the Queen was greater than many journalists had expected.

What was Elizabeth's mother's name?

Problem: Apollo:

In his role as god of prophecy and truth, Apollo had the epithets Manticus (/ˈmæntᵻkəs/ MAN-ti-kəs; Μαντικός, Mantikos, literally "prophetic"), Leschenorius (/ˌlɛskᵻˈnɔəriəs/ LES-ki-NOHR-ee-əs; Λεσχηνόριος, Leskhēnorios, from λεσχήνωρ, "converser"), and Loxias (/ˈlɒksiəs/ LOK-see-əs; Λοξίας, Loxias, from λέγειν, "to say"). The epithet "Loxias" has historically been associated with λοξός, "ambiguous". In this respect, the Romans called him Coelispex (/ˈsɛlᵻspɛks/ SEL-i-speks; from Latin coelum, "sky", and specere, "to look at"). The epithet Iatromantis (/aɪˌætrəˈmæntɪs/ eye-AT-rə-MAN-tis; Ἰατρομάντις, Iātromantis, from ἰατρός, "physician", and μάντις, "prophet") refers to both his role as a god of healing and of prophecy. As god of music and arts, Apollo had the epithet Musagetes (/mjuːˈsædʒᵻtiːz/ mew-SAJ-i-teez; Doric Μουσαγέτας, Mousāgetās) or Musegetes (/mjuːˈsɛdʒᵻtiːz/ mew-SEJ-i-teez; Μουσηγέτης, Mousēgetēs, from Μούσα, "Muse", and ἡγέτης, "leader").

Problem: Elizabeth II:

In February 1974, the British Prime Minister, Edward Heath, advised the Queen to call a general election in the middle of her tour of the Austronesian Pacific Rim, requiring her to fly back to Britain. The election resulted in a hung parliament; Heath's Conservatives were not the largest party, but could stay in office if they formed a coalition with the Liberals. Heath only resigned when discussions on forming a coalition foundered, after which the Queen asked the Leader of the Opposition, Labour's Harold Wilson, to form a government.
