Problem: Uranium:

Most ingested uranium is excreted during digestion. Only 0.5% is absorbed when insoluble forms of uranium, such as its oxide, are ingested, whereas absorption of the more soluble uranyl ion can be up to 5%. However, soluble uranium compounds tend to quickly pass through the body, whereas insoluble uranium compounds, especially when inhaled by way of dust into the lungs, pose a more serious exposure hazard. After entering the bloodstream, the absorbed uranium tends to bioaccumulate and stay for many years in bone tissue because of uranium's affinity for phosphates. Uranium is not absorbed through the skin, and alpha particles released by uranium cannot penetrate the skin.

About what percentage of uranium oxide is absorbed when ingested?

A: 0.5%

Problem: IMF's forecast said that Greece's unemployment rate would hit the highest 14.8 percent in 2012 and decrease to 14.1 in 2014. But in fact, the Greek economy suffered a prolonged high unemployemnt. The unemployment figure was between 9 per cent and 11 per cent in 2009, and it soared to 28 per cent in 2013. In 2015, Greece's jobless rate is around 24 per cent. It is thought that Greece's potential output has been eroded by this prolonged massive unemployment due to the associated hysteresis effects.
What did IMF forecast Greece's unemployment rate to be in 2012?

Answer: 14.8 percent

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There is currently no precise test with the diagnosis typically based on the pattern of symptoms and response to therapy over time. A diagnosis of asthma should be suspected if there is a history of: recurrent wheezing, coughing or difficulty breathing and these symptoms occur or worsen due to exercise, viral infections, allergens or air pollution. Spirometry is then used to confirm the diagnosis. In children under the age of six the diagnosis is more difficult as they are too young for spirometry.
Is there a test to determine asthma in an individual?
A: There is currently no precise test

Context and question: Most Western European countries changed the start of the year to 1 January before they adopted the Gregorian calendar. For example, Scotland changed the start of the Scottish New Year to 1 January in 1600 (this means that 1599 was a short year). England, Ireland and the British colonies changed the start of the year to 1 January in 1752 (so 1751 was a short year with only 282 days) though in England the start of the tax year remained at 25 March (O.S.), 5 April (N.S.) till 1800, when it moved to 6 April. Later in 1752 in September the Gregorian calendar was introduced throughout Britain and the British colonies (see the section Adoption). These two reforms were implemented by the Calendar (New Style) Act 1750.
What do most European countries do after they adopted the Gregorian calendar?
Answer: unanswerable

Question: The value judgement definition of literature considers it to exclusively include writing that possesses high quality or distinction, forming part of the so-called belles-lettres ('fine writing') tradition. This is the definition used in the Encyclopdia Britannica Eleventh Edition (191011) when it classifies literature as "the best expression of the best thought reduced to writing." However, this has the result that there is no objective definition of what constitutes "literature"; anything can be literature, and anything which is universally regarded as literature has the potential to be excluded, since value-judgements can change over time.
Is there an answer to this question: How does the Encyclopedia Britannia Tenth Edition classify literature?

Answer: unanswerable

Problem: Separation of church and state in the United States:

Some scholars and organizations disagree with the notion of "separation of church and state", or the way the Supreme Court has interpreted the constitutional limitation on religious establishment. Such critics generally argue that the phrase misrepresents the textual requirements of the Constitution, while noting that many aspects of church and state were intermingled at the time the Constitution was ratified. These critics argue that the prevalent degree of separation of church and state could not have been intended by the constitutional framers. Some of the intermingling between church and state include religious references in official contexts, and such other founding documents as the United States Declaration of Independence, which references the idea of a "Creator" and "Nature's God", though these references did not ultimately appear in the Constitution nor do they mention any particular religious view of a "Creator" or "Nature's God."

What do scholars also agree with about the way the Supreme Court has interpreted what?
