Problem: Gregorian calendar:

The Gregorian calendar is a solar calendar. A regular Gregorian year consists of 365 days, but as in the Julian calendar, in a leap year, a leap day is added to February. In the Julian calendar a leap year occurs every 4 years, but the Gregorian calendar omits 3 leap days every 400 years. In the Julian calendar, this leap day was inserted by doubling 24 February, and the Gregorian reform did not change the date of the leap day. In the modern period, it has become customary to number the days from the beginning of the month, and February 29th is often considered as the leap day. Some churches, notably the Roman Catholic Church, delay February festivals after the 23rd by one day in leap years.

Which church still host festivals on the twenty-third in leap years?

A: unanswerable


Problem: Saint Barthélemy, a volcanic island fully encircled by shallow reefs, has an area of 25 square kilometres (9.7 sq mi) and a population of 9,035 (Jan. 2011 estimate). Its capital is Gustavia[citation needed], which also contains the main harbour to the island. It is the only Caribbean island which was a Swedish colony for any significant length of time; Guadeloupe was under Swedish rule only briefly at the end of the Napoleonic Wars. Symbolism from the Swedish national arms, the Three Crowns, still appears in the island's coat of arms. The language, cuisine, and culture, however, are distinctly French. The island is a popular tourist destination during the winter holiday season, especially for the rich and famous during the Christmas and new year period.
How many tourists visit Saint Barthelemy each year?

Antarctica is the coldest of Earth's continents. The coldest natural temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Soviet (now Russian) Vostok Station in Antarctica on 21 July 1983. For comparison, this is 10.7 °C (20 °F) colder than subliming dry ice at one atmosphere of partial pressure, but since CO2 only makes up 0.039% of air, temperatures of less than −150 °C (−238 °F) would be needed to produce dry ice snow in Antarctica. Antarctica is a frozen desert with little precipitation; the South Pole itself receives less than 10 cm (4 in) per year, on average. Temperatures reach a minimum of between −80 °C (−112 °F) and −89.2 °C (−128.6 °F) in the interior in winter and reach a maximum of between 5 °C (41 °F) and 15 °C (59 °F) near the coast in summer. Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world.
What light caused condition is a serious problem for humans in Antarctica?
A: Sunburn


Context and question: The United States and the Soviet Union were the first two countries to recognize the State of Israel, having declared recognition roughly simultaneously. The United States regards Israel as its "most reliable partner in the Middle East," based on "common democratic values, religious affinities, and security interests". Their bilateral relations are multidimensional and the United States is the principal proponent of the Arab-Israeli peace process. The United States and Israeli views differ on some issues, such as the Golan Heights, Jerusalem, and settlements. The United States has provided $68 billion in military assistance and $32 billion in grants to Israel since 1967, under the Foreign Assistance Act (period beginning 1962), more than any other country for that period until 2003.
How much did the United States provide in military assistance?
Answer: $68 billion


Question: Chain department stores grew rapidly after 1920, and provided competition for the downtown upscale department stores, as well as local department stores in small cities. J. C. Penney had four stores in 1908, 312 in 1920, and 1452 in 1930. Sears, Roebuck & Company, a giant mail-order house, opened its first eight retail stores in 1925, and operated 338 by 1930, and 595 by 1940. The chains reached a middle-class audience, that was more interested in value than in upscale fashions. Sears was a pioneer in creating department stores that catered to men as well as women, especially with lines of hardware and building materials. It deemphasized the latest fashions in favor of practicality and durability, and allowed customers to select goods without the aid of a clerk. Its stores were oriented to motorists – set apart from existing business districts amid residential areas occupied by their target audience; had ample, free, off-street parking; and communicated a clear corporate identity. In the 1930s, the company designed fully air-conditioned, "windowless" stores whose layout was driven wholly by merchandising concerns.
Is there an answer to this question: What demographic were most stores focusing on?

Answer: middle-class audience
