Problem: The first large, diverse lineage of short-tailed avialans to evolve were the enantiornithes, or "opposite birds", so named because the construction of their shoulder bones was in reverse to that of modern birds. Enantiornithes occupied a wide array of ecological niches, from sand-probing shorebirds and fish-eaters to tree-dwelling forms and seed-eaters. While they were the dominant group of avialans during the Cretaceous period, enantiornithes became extinct along with many other dinosaur groups at the end of the Mesozoic era.
Because of the construction of their shoulder bones, what were the enantiornithes called?
The answer is the following: opposite birds

John's first wife, Isabel, Countess of Gloucester, was released from imprisonment in 1214; she remarried twice, and died in 1217. John's second wife, Isabella of Angouleme, left England for Angouleme soon after the king's death; she became a powerful regional leader, but largely abandoned the children she had had by John. John had five legitimate children, all by Isabella. His eldest son, Henry III, ruled as king for the majority of the 13th century. Richard became a noted European leader and ultimately the King of the Romans in the Holy Roman Empire. Joan married Alexander II of Scotland to become his queen consort. Isabella married the Holy Roman Emperor Frederick II. His youngest daughter, Eleanor, married William Marshal's son, also called William, and later the famous English rebel Simon de Montfort. John had a number of illegitimate children by various mistresses, including nine sons Richard, Oliver, John, Geoffrey, Henry, Osbert Gifford, Eudes, Bartholomew and probably Philip and three daughters Joan, Maud and probably Isabel. Of these, Joan became the most famous, marrying Prince Llywelyn the Great of Wales.
Who did Joan marry to become queen consort?
Alexander II of Scotland

Input: Party leaders of the United States House of Representatives
The roles and responsibilities of the minority leader are not well-defined. To a large extent, the functions of the minority leader are defined by tradition and custom. A minority leader from 1931 to 1939, Representative Bertrand Snell, R-N.Y., provided this "job description": "He is spokesman for his party and enunciates its policies. He is required to be alert and vigilant in defense of the minority's rights. It is his function and duty to criticize constructively the policies and programs of the majority, and to this end employ parliamentary tactics and give close attention to all proposed legislation."

Are minority leadership roles specified closely?
Output: are not well-defined

Input: Article: Jefferson and Madison's approach was not the only one taken in the eighteenth century. Jefferson's Statute of Religious Freedom was drafted in opposition to a bill, chiefly supported by Patrick Henry, which would permit any Virginian to belong to any denomination, but which would require him to belong to some denomination and pay taxes to support it. Similarly, the Constitution of Massachusetts originally provided that "no subject shall be hurt, molested, or restrained, in his person, liberty, or estate, for worshipping God in the manner and season most agreeable to the dictates of his own conscience... provided he doth not disturb the public peace, or obstruct others in their religious worship," (Article II) but also that:

Now answer this question: Who was the chief supporter of the bill that got Jefferson motivated to draft his Statute?

Output: Patrick Henry

Article: Raleigh receives an average of 6.0 inches (15.2 cm) of snow in winter. Freezing rain and sleet also occur most winters, and occasionally the area experiences a major damaging ice storm. On January 2425, 2000, Raleigh received its greatest snowfall from a single storm 20.3 inches (52 cm) the Winter Storm of January 2000. Storms of this magnitude are generally the result of cold air damming that affects the city due to its proximity to the Appalachian Mountains. Winter storms have caused traffic problems in the past as well.

Question: What caused the Winter Storm of 2000?
Ans: cold air damming

Input: Macintosh
Apple discontinued the use of PowerPC microprocessors in 2006. At WWDC 2005, Steve Jobs announced this transition, revealing that Mac OS X was always developed to run on both the Intel and PowerPC architectures. All new Macs now use x86 processors made by Intel, and some were renamed as a result. Intel-based Macs running OS X 10.6 and below (support has been discontinued since 10.7) can run pre-existing software developed for PowerPC using an emulator called Rosetta, although at noticeably slower speeds than native programs. However, the Classic environment is unavailable on the Intel architecture. Intel chips introduced the potential to run the Microsoft Windows operating system natively on Apple hardware, without emulation software such as Virtual PC. In March 2006, a group of hackers announced that they were able to run Windows XP on an Intel-based Mac. The group released their software as open source and has posted it for download on their website. On April 5, 2006, Apple announced the availability of the public beta of Boot Camp, software that allows owners of Intel-based Macs to install Windows XP on their machines; later versions added support for Windows Vista and Windows 7. Classic was discontinued in Mac OS X 10.5, and Boot Camp became a standard feature on Intel-based Macs.

When did Apple discontinue the use of PowerPC microprocessors?
Output:
2006
