Problem: Kanye West:

On November 10, 2007, at approximately 7:35 pm, paramedics responding to an emergency call transported West's mother, Donda West, to the nearby Centinela Freeman Hospital in Marina del Rey, California. She was unresponsive in the emergency room, and after resuscitation attempts, doctors pronounced her dead at approximately 8:30 pm, at age 58. The Los Angeles County coroner's office said in January 2008 that West had died of heart disease while suffering "multiple post-operative factors" after plastic surgery. She had undergone liposuction and breast reduction. Beverly Hills plastic surgeon Andre Aboolian had refused to do the surgery because West had a health condition that placed her at risk for a heart attack. Aboolian referred her to an internist to investigate her cardiac issue. She never met with the doctor recommended by Aboolian and had the procedures performed by a third doctor, Jan Adams.

What was the name of the doctor who performed the surgery that ended up killing Donda West?

A: Jan Adams


Problem: In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
What does a hot object in equilibrium reflect as much as it emits?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Patassé purged many of the Kolingba elements from the government and Kolingba supporters accused Patassé's government of conducting a "witch hunt" against the Yakoma. A new constitution was approved on 28 December 1994 but had little impact on the country's politics. In 1996–1997, reflecting steadily decreasing public confidence in the government's erratic behaviour, three mutinies against Patassé's administration were accompanied by widespread destruction of property and heightened ethnic tension. During this time (1996) the Peace Corps evacuated all its volunteers to neighboring Cameroon. To date, the Peace Corps has not returned to the Central African Republic. The Bangui Agreements, signed in January 1997, provided for the deployment of an inter-African military mission, to Central African Republic and re-entry of ex-mutineers into the government on 7 April 1997. The inter-African military mission was later replaced by a U.N. peacekeeping force (MINURCA).
As of today what group has not returned to Yakoma?
A: unanswerable


Context and question: As the 10th century progressed, the Khazars were no longer able to command tribute from the Volga Bulgars, and their relationship with the Byzantines deteriorated, as Byzantium increasingly allied with the Pechenegs against them. The Pechenegs were thus secure to raid the lands of the Khazars from their base between the Volga and Don rivers, allowing them to expand to the west. Rus' relations with the Pechenegs were complex, as the groups alternately formed alliances with and against one another. The Pechenegs were nomads roaming the steppe raising livestock which they traded with the Rus' for agricultural goods and other products. The lucrative Rus' trade with the Byzantine Empire had to pass through Pecheneg-controlled territory, so the need for generally peaceful relations was essential. Nevertheless, while the Primary Chronicle reports the Pechenegs entering Rus' territory in 915 and then making peace, they were waging war with one another again in 920. Pechenegs are reported assisting the Rus' in later campaigns against the Byzantines, yet allied with the Byzantines against the Rus' at other times.
Around what time did the Khazars unable to no longer command tribute from Volga?
Answer: 10th century


Question: Temperatures below 0 °C (32 °F) or above 25 °C (77 °F) are rare. Cork Airport records an average of 1,227.9 millimetres (4.029 ft) of precipitation annually, most of which is rain. The airport records an average of 7 days of hail and 11 days of snow or sleet a year; though it only records lying snow for 2 days of the year. The low altitude of the city, and moderating influences of the harbour, mean that lying snow very rarely occurs in the city itself. There are on average 204 "rainy" days a year (over 0.2 millimetres (0.0079 in) of rainfall), of which there are 73 days with "heavy rain" (over 5 millimetres (0.20 in)). Cork is also a generally foggy city, with an average of 97 days of fog a year, most common during mornings and during winter. Despite this, however, Cork is also one of Ireland's sunniest cities, with an average of 3.9 hours of sunshine every day and only having 67 days where there is no "recordable sunshine", mostly during and around winter.
Is there an answer to this question: What influence does the harbor have on Ireland's lack of lying snow?

Answer: unanswerable

LaserDisc's support for multiple audio tracks allowed for vast supplemental materials to be included on-disc and made it the first available format for "Special Edition" releases; the 1984 Criterion Collection edition of Citizen Kane is generally credited as being the first "Special Edition" release to home video,[citation needed] and for setting the standard by which future SE discs were measured. The disc provided interviews, commentary tracks, documentaries, still photographs, and other features for historians and collectors.
LaserDisc was the first format to provide what type of releases to consumers?
A:
"Special Edition"
