Problem: Uranium:

Calcined uranium yellowcake, as produced in many large mills, contains a distribution of uranium oxidation species in various forms ranging from most oxidized to least oxidized. Particles with short residence times in a calciner will generally be less oxidized than those with long retention times or particles recovered in the stack scrubber. Uranium content is usually referenced to U
3O
8, which dates to the days of the Manhattan project when U
3O
8 was used as an analytical chemistry reporting standard.

What contains a distribution of uranium deoxidation species in various forms ranging from most oxidized to least oxidized?

A: unanswerable


Problem: Great power:

With continuing European integration, the European Union is increasingly being seen as a great power in its own right, with representation at the WTO and at G8 and G-20 summits. This is most notable in areas where the European Union has exclusive competence (i.e. economic affairs). It also reflects a non-traditional conception of Europe's world role as a global "civilian power", exercising collective influence in the functional spheres of trade and diplomacy, as an alternative to military dominance. The European Union is a supranational union and not a sovereign state, and has limited scope in the areas of foreign affairs and defence policy. These remain largely with the member states of the European Union, which include the three great powers of France, Germany and the United Kingdom (referred to as the "EU three").

In what area is the WTO exclusively competent?

A: unanswerable


Problem: San Diego:

The climate in San Diego, like most of Southern California, often varies significantly over short geographical distances resulting in microclimates. In San Diego, this is mostly because of the city's topography (the Bay, and the numerous hills, mountains, and canyons). Frequently, particularly during the "May gray/June gloom" period, a thick "marine layer" cloud cover will keep the air cool and damp within a few miles of the coast, but will yield to bright cloudless sunshine approximately 5–10 miles (8.0–16.1 km) inland. Sometimes the June gloom can last into July, causing cloudy skies over most of San Diego for the entire day. Even in the absence of June gloom, inland areas tend to experience much more significant temperature variations than coastal areas, where the ocean serves as a moderating influence. Thus, for example, downtown San Diego averages January lows of 50 °F (10 °C) and August highs of 78 °F (26 °C). The city of El Cajon, just 10 miles (16 km) inland from downtown San Diego, averages January lows of 42 °F (6 °C) and August highs of 88 °F (31 °C).

What areas experience the most insignificant temperature variations?

A: unanswerable


Problem: Westminster Abbey:

Between 1042 and 1052 King Edward the Confessor began rebuilding St Peter's Abbey to provide himself with a royal burial church. It was the first church in England built in the Romanesque style. The building was not completed until around 1090 but was consecrated on 28 December 1065, only a week before Edward's death on 5 January 1066. A week later he was buried in the church, and nine years later his wife Edith was buried alongside him. His successor, Harold II, was probably crowned in the abbey, although the first documented coronation is that of William the Conqueror later the same year.

What style was the church rebuilt in?
---
A:
Romanesque
