The problem: Answer a question about this article:
Several Americans, especially Benjamin Franklin and Thomas Jefferson, played a major role in bringing Enlightenment ideas to the New World and in influencing British and French thinkers. Franklin was influential for his political activism and for his advances in physics. The cultural exchange during the Age of Enlightenment ran in both directions across the Atlantic. Thinkers such as Paine, Locke, and Rousseau all take Native American cultural practices as examples of natural freedom. The Americans closely followed English and Scottish political ideas, as well as some French thinkers such as Montesquieu. As deists, they were influenced by ideas of John Toland (1670–1722) and Matthew Tindal (1656–1733). During the Enlightenment there was a great emphasis upon liberty, democracy, republicanism and religious tolerance. Attempts to reconcile science and religion resulted in a widespread rejection of prophecy, miracle and revealed religion in preference for Deism – especially by Thomas Paine in The Age of Reason and by Thomas Jefferson in his short Jefferson Bible – from which all supernatural aspects were removed.
Which American Enlightenment sympathiser was known for his political activism and advances in physics?
****
The answer: Benjamin Franklin


Problem: Please answer a question about the following article about Glacier:
Before glaciation, mountain valleys have a characteristic "V" shape, produced by eroding water. During glaciation, these valleys are widened, deepened, and smoothed, forming a "U"-shaped glacial valley. The erosion that creates glacial valleys eliminates the spurs of earth that extend across mountain valleys, creating triangular cliffs called truncated spurs. Within glacial valleys, depressions created by plucking and abrasion can be filled by lakes, called paternoster lakes. If a glacial valley runs into a large body of water, it forms a fjord.
What shape do glacial valleys have after being widened by glacation?
A: "U"-shaped

Dallin H. Oaks replaced Wilkinson as president in 1971. Oaks continued the expansion of his predecessor, adding a law school and proposing plans for a new School of Management. During his administration, a new library was also added, doubling the library space on campus. Jeffrey R. Holland followed as president in 1980, encouraging a combination of educational excellence and religious faith at the university. He believed that one of the school's greatest strengths was its religious nature and that this should be taken advantage of rather than hidden. During his administration, the university added a campus in Jerusalem, now called the BYU Jerusalem Center. In 1989, Holland was replaced by Rex E. Lee. Lee was responsible for the Benson Science Building and the Museum of Art on campus. A cancer victim, Lee is memorialized annually at BYU during a cancer fundraiser called the Rex Lee Run. Shortly before his death, Lee was replaced in 1995 by Merrill J. Bateman.

What did Jeffrey R. Holland believe to be BYU's strongest asset?
Answer: its religious nature


Problem: Courts check both the executive branch and the legislative branch through judicial review. This concept is not written into the Constitution, but was envisioned by many of the Constitution's Framers (for example, The Federalist Papers mention it). The Supreme Court established a precedent for judicial review in Marbury v. Madison. There were protests by some at this decision, born chiefly of political expediency, but political realities in the particular case paradoxically restrained opposing views from asserting themselves. For this reason, precedent alone established the principle that a court may strike down a law it deems unconstitutional.
Who is responsible for judicial review?
The answer is the following: Courts


It is estimated that in 480 BC, 50 million people lived in the Achaemenid Empire. The empire at its peak ruled over 44% of the world's population, the highest such figure for any empire in history. In Greek history, the Achaemenid Empire is considered as the antagonist of the Greek city states, for the emancipation of slaves including the Jewish exiles in Babylon, building infrastructures such as road and postal systems, and the use of an official language, the Imperial Aramaic, throughout its territories. The empire had a centralized, bureaucratic administration under the emperor, a large professional army, and civil services, inspiring similar developments in later empires. Furthermore, one of the Seven Wonders of the Ancient World, the Mausoleum at Halicarnassus, was built in the empire between 353 and 350 BC.
What was the Achaemenid Empire's official language?
Imperial Aramaic


Here is a question about this article: Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit (two 8-bit bytes) for each character but cannot encode every character in the current Unicode standard. UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units (4 × 8 bits) to handle each of the additional characters.
What is the answer to this question: How are two 16-bit units used? 
****
So...
(4 × 8 bits
