Problem: Prime minister:

The convention in the English language is to call nearly all national heads of government "prime minister" (sometimes modified to the equivalent term of premier), regardless of the correct title of the head of government as applied in his or her respective country. The few exceptions to the rule are Germany and Austria, whose heads of government titles are almost always translated as Chancellor; Monaco, whose head of government is referred to as the Minister of State; and Vatican City, for which the head of government is titled the Secretary of State. In the case of Ireland, the head of government is occasionally referred to as the Taoiseach by English speakers. A stand-out case is the President of Iran, who is not actually a head of state, but the head of the government of Iran. He is referred to as "president" in both the Persian and English languages.

Problem: Department stores today have sections that sell the following: clothing, furniture, home appliances, toys, cosmetics, gardening, toiletries, sporting goods, do it yourself, paint, and hardware and additionally select other lines of products such as food, books, jewelry, electronics, stationery, photographic equipment, baby products, and products for pets. Customers check out near the front of the store or, alternatively, at sales counters within each department. Some are part of a retail chain of many stores, while others may be independent retailers. In the 1970s, they came under heavy pressure from discounters. Since 2010, they have come under even heavier pressure from online stores such as Amazon.
Who stopped influencing department stores in the 1970's?

Residential architecture is not defined by a single architectural style, but rather an eclectic mix of houses, townhouses, condominiums, and apartment buildings in the metropolitan area (particularly in areas of urban sprawl). Free standing dwellings with relatively large gardens are perhaps the most common type of housing outside inner city Melbourne. Victorian terrace housing, townhouses and historic Italianate, Tudor revival and Neo-Georgian mansions are all common in neighbourhoods such as Toorak.
Are townhouses, condominiums, and apartment buildings found more prevalent in the metropolitan area or outside the city?
A: metropolitan area (particularly in areas of urban sprawl)

Context and question: About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.
What continent has 70% of the worlds ice?
Answer: unanswerable

Question: While other companies were moving on to 32-bit systems, Rare and Nintendo proved that the SNES was still a strong contender in the market. In November 1994, Rare released Donkey Kong Country, a platform game featuring 3D models and textures pre-rendered on SGI workstations. With its detailed graphics, fluid animation and high-quality music, Donkey Kong Country rivaled the aesthetic quality of games that were being released on newer 32-bit CD-based consoles. In the last 45 days of 1994, the game sold 6.1 million units, making it the fastest-selling video game in history to that date. This game sent a message that early 32-bit systems had little to offer over the SNES, and helped make way for the more advanced consoles on the horizon.
Is there an answer to this question: How many copies of Donkey Kong Country were sold in November 1994?

Traditionally, Switzerland avoids alliances that might entail military, political, or direct economic action and has been neutral since the end of its expansion in 1515. Its policy of neutrality was internationally recognised at the Congress of Vienna in 1815. Only in 2002 did Switzerland become a full member of the United Nations and it was the first state to join it by referendum. Switzerland maintains diplomatic relations with almost all countries and historically has served as an intermediary between other states. Switzerland is not a member of the European Union; the Swiss people have consistently rejected membership since the early 1990s. However, Switzerland does participate in the Schengen Area.
What have the Swiss people continually rejected membership in since the 1990's?
A:
European Union
