The problem: Answer a question about this article:
Traditionally, major college basketball teams began their seasons with a few exhibition games. They played travelling teams made up of former college players on teams such as Athletes in Action or a team sponsored by Marathon Oil. On occasion before 1992, when FIBA allowed professional players on foreign national teams, colleges played those teams in exhibitions. However, in 2003, the National Collegiate Athletic Association banned games with non-college teams. Some teams have begun scheduling exhibition games against teams in NCAA Division II and NCAA Division III, or even against colleges and universities located in Canada. Major college basketball teams still travel to other countries during the summer to play in exhibition games, although a college team is allowed one foreign tour every four years, and a maximum of ten games in each tour.
What is an example of a team of former college players?
****
The answer: Athletes in Action

Problem: Please answer a question about the following article about United States Air Force:
Aeromedical Evacuation is "the movement of patients under medical supervision to and between medical treatment facilities by air transportation" (JP 1-02). JP 4-02, Health Service Support, further defines it as "the fixed wing movement of regulated casualties to and between medical treatment facilities, using organic and/or contracted mobility airframes, with aircrew trained explicitly for this mission." Aeromedical evacuation forces can operate as far forward as fixed-wing aircraft are able to conduct airland operations.
Who operates and is able to conduct airland missions?
A: Aeromedical evacuation forces

Whereas Greg had limited his illustrative examples to English Renaissance drama, where his expertise lay, Bowers argued that the rationale was "the most workable editorial principle yet contrived to produce a critical text that is authoritative in the maximum of its details whether the author be Shakespeare, Dryden, Fielding, Nathaniel Hawthorne, or Stephen Crane. The principle is sound without regard for the literary period." For works where an author's manuscript survived a case Greg had not considered Bowers concluded that the manuscript should generally serve as copy-text. Citing the example of Nathaniel Hawthorne, he noted:

What where the limitations of Greg's analyses?
Answer: English Renaissance drama

Problem: Athanasius's episcopate began on 9 May 328 as the Alexandrian Council elected Athanasius to succeed the aged Alexander. That council also denounced various heresies and schisms, many of which continued to preoccupy his 45-year-long episcopate (c. 8 June 328 2 May 373). Patriarch Athanasius spent over 17 years in five exiles ordered by four different Roman Emperors, not counting approximately six more incidents in which Athanasius fled Alexandria to escape people seeking to take his life. This gave rise to the expression "Athanasius contra mundum" or "Athanasius against the world". However, during his first years as bishop, Athanasius visited the churches of his territory, which at that time included all of Egypt and Libya. He established contacts with the hermits and monks of the desert, including Pachomius, which proved very valuable to him over the years. Shortly thereafter, Athanasius became occupied with the theological disputes against Arians within the Byzantine Empire that would occupy much of his life.
Who did Athanasius succeed?
The answer is the following: Alexander

Here is a question about this article: The simplest known circadian clock is that of the prokaryotic cyanobacteria. Recent research has demonstrated that the circadian clock of Synechococcus elongatus can be reconstituted in vitro with just the three proteins (KaiA, KaiB, KaiC) of their central oscillator. This clock has been shown to sustain a 22-hour rhythm over several days upon the addition of ATP. Previous explanations of the prokaryotic circadian timekeeper were dependent upon a DNA transcription/translation feedback mechanism.[citation needed]
What is the answer to this question: What type of feedback mechanism was previously thought to be needed to sustain the clock?
****
So...
DNA
