Problem: Renewable energy commercialization:

Nearly all the gasoline sold in the United States today is mixed with 10 percent ethanol, a mix known as E10, and motor vehicle manufacturers already produce vehicles designed to run on much higher ethanol blends. Ford, DaimlerChrysler, and GM are among the automobile companies that sell flexible-fuel cars, trucks, and minivans that can use gasoline and ethanol blends ranging from pure gasoline up to 85% ethanol (E85). The challenge is to expand the market for biofuels beyond the farm states where they have been most popular to date. The Energy Policy Act of 2005, which calls for 7.5 billion US gallons (28,000,000 m3) of biofuels to be used annually by 2012, will also help to expand the market.

Nearly all gasoline sold in the UK is mixed with what percentage of ethanol?

Problem: Montana's motto, Oro y Plata, Spanish for "Gold and Silver", recognizing the significant role of mining, was first adopted in 1865, when Montana was still a territory. A state seal with a miner's pick and shovel above the motto, surrounded by the mountains and the Great Falls of the Missouri River, was adopted during the first meeting of the territorial legislature in 1864–65. The design was only slightly modified after Montana became a state and adopted it as the Great Seal of the State of Montana, enacted by the legislature in 1893. The state flower, the bitterroot, was adopted in 1895 with the support of a group called the Floral Emblem Association, which formed after Montana's Women's Christian Temperance Union adopted the bitterroot as the organization's state flower. All other symbols were adopted throughout the 20th century, save for Montana's newest symbol, the state butterfly, the mourning cloak, adopted in 2001, and the state lullaby, "Montana Lullaby", adopted in 2007.
When was the motto adopted?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Russell's ministry, though Whig, was not favoured by the Queen. She found particularly offensive the Foreign Secretary, Lord Palmerston, who often acted without consulting the Cabinet, the Prime Minister, or the Queen. Victoria complained to Russell that Palmerston sent official dispatches to foreign leaders without her knowledge, but Palmerston was retained in office and continued to act on his own initiative, despite her repeated remonstrances. It was only in 1851 that Palmerston was removed after he announced the British government's approval of President Louis-Napoleon Bonaparte's coup in France without consulting the Prime Minister. The following year, President Bonaparte was declared Emperor Napoleon III, by which time Russell's administration had been replaced by a short-lived minority government led by Lord Derby.
To whom didn't Victoria complain about Palmerston?
A: unanswerable


Context and question: The required beliefs of these clauses include belief in a Supreme Being and belief in a future state of rewards and punishments. (Tennessee Constitution Article IX, Section 2 is one such example.) Some of these same states specify that the oath of office include the words "so help me God." In some cases these beliefs (or oaths) were historically required of jurors and witnesses in court. At one time, such restrictions were allowed under the doctrine of states' rights; today they are deemed to be in violation of the federal First Amendment, as applied to the states via the 14th amendment, and hence unconstitutional and unenforceable.
Because such oaths are in violation of the First Amendment, they're what?
Answer: unconstitutional and unenforceable


Question: In Rome, Nero and his architects used mosaics to cover some surfaces of walls and ceilings in the Domus Aurea, built 64 AD, and wall mosaics are also found at Pompeii and neighbouring sites. However it seems that it was not until the Christian era that figural wall mosaics became a major form of artistic expression. The Roman church of Santa Costanza, which served as a mausoleum for one or more of the Imperial family, has both religious mosaic and decorative secular ceiling mosaics on a round vault, which probably represent the style of contemporary palace decoration.
Is there an answer to this question: When did figure wall mosaics become the highest form of artistic expression?

Answer: the Christian era


On August 18, 2011, the CRTC issued a decision that allows CBC's mandatory market rebroadcasting transmitters in analogue to remain on-air until August 31, 2012. Before that deadline, CBC's licence renewal process would take place and CBC's digital transition plans would be examined as part of that process. The requirement remains for all of CBC's full-power transmitters occupying channels 52 to 69 to either relocate to channels 2 to 51 or become low-power transmitters. In some cases, CBC has opted to reduce the power of existing transmitters to low-power transmitters, which will result in signal loss for some viewers.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The CRTC stated that the CBC  refused to relocate and reduce in power what channels?
Ah, so..
unanswerable
