Problem: Crucifixion of Jesus:

Although almost all ancient sources relating to crucifixion are literary, the 1968 archeological discovery just northeast of Jerusalem of the body of a crucified man dated to the 1st century provided good confirmatory evidence that crucifixions occurred during the Roman period roughly according to the manner in which the crucifixion of Jesus is described in the gospels. The crucified man was identified as Yehohanan ben Hagkol and probably died about 70 AD, around the time of the Jewish revolt against Rome. The analyses at the Hadassah Medical School estimated that he died in his late 20s. Another relevant archaeological find, which also dates to the 1st century AD, is an unidentified heel bone with a spike discovered in a Jerusalem gravesite, now held by the Israel Antiquities Authority and displayed in the Israel Museum.

What year was the Israel Museum established?

Problem: Some countries are eliminating or reducing climate disrupting subsidies and Belgium, France, and Japan have phased out all subsidies for coal. Germany is reducing its coal subsidy. The subsidy dropped from $5.4 billion in 1989 to $2.8 billion in 2002, and in the process Germany lowered its coal use by 46 percent. China cut its coal subsidy from $750 million in 1993 to $240 million in 1995 and more recently has imposed a high-sulfur coal tax. However, the United States has been increasing its support for the fossil fuel and nuclear industries.
What country is reducing its coal subsidy?

Context and question: There is also a range of independent or public schools. Many of these are for pupils between 11 and 18 years, such as King's College, Taunton and Taunton School. King's School, Bruton, was founded in 1519 and received royal foundation status around 30 years later in the reign of Edward VI. Millfield is the largest co-educational boarding school. There are also preparatory schools for younger children, such as All Hallows, and Hazlegrove Preparatory School. Chilton Cantelo School offers places both to day pupils and boarders aged 7 to 16. Other schools provide education for children from the age of 3 or 4 years through to 18, such as King Edward's School, Bath, Queen's College, Taunton and Wells Cathedral School which is one of the five established musical schools for school-age children in Britain. Some of these schools have religious affiliations, such as Monkton Combe School, Prior Park College, Sidcot School which is associated with the Religious Society of Friends, Downside School which is a Roman Catholic public school in Stratton-on-the-Fosse, situated next to the Benedictine Downside Abbey, and Kingswood School, which was founded by John Wesley in 1748 in Kingswood near Bristol, originally for the education of the sons of the itinerant ministers (clergy) of the Methodist Church.

Question: In the midst of the European sovereign-debt crisis, Radek Sikorski, Poland's Foreign Minister, stated in November 2011, "I will probably be the first Polish foreign minister in history to say so, but here it is: I fear German power less than I am beginning to fear German inactivity. You have become Europe's indispensable nation." According to Jacob Heilbrunn, a senior editor at The National Interest, such a statement is unprecedented when taking into consideration Germany's history. "This was an extraordinary statement from a top official of a nation that was ravaged by Germany during World War II. And it reflects a profound shift taking place throughout Germany and Europe about Berlin's position at the center of the Continent." Heilbrunn believes that the adage, "what was good for Germany was bad for the European Union" has been supplanted by a new mentalitywhat is in the interest of Germany is also in the interest of its neighbors. The evolution in Germany's national identity stems from focusing less on its Nazi past and more on its Prussian history, which many Germans believe was betrayedand not representedby Nazism. The evolution is further precipitated by Germany's conspicuous position as Europe's strongest economy. Indeed, this German sphere of influence has been welcomed by the countries that border it, as demonstrated by Polish foreign minister Radek Sikorski's effusive praise for his country's western neighbor. This shift in thinking is boosted by a newer generation of Germans who see World War II as a distant memory.
Is there an answer to this question: What Polish foreign minister said he feared German power?

Answer: unanswerable

Problem: Green:

There is no green pigment in green eyes; like the color of blue eyes, it is an optical illusion; its appearance is caused by the combination of an amber or light brown pigmentation of the stroma, given by a low or moderate concentration of melanin, with the blue tone imparted by the Rayleigh scattering of the reflected light. Green eyes are most common in Northern and Central Europe. They can also be found in Southern Europe, West Asia, Central Asia, and South Asia. In Iceland, 89% of women and 87% of men have either blue or green eye color. A study of Icelandic and Dutch adults found green eyes to be much more prevalent in women than in men. Among European Americans, green eyes are most common among those of recent Celtic and Germanic ancestry, about 16%.

What is the appearance of green in th eyes attributed to?

A:
an optical illusion
