Input: Read this: In the 1960 presidential election, Democratic candidate and future President John F. Kennedy "criticized President Eisenhower for not ending discrimination in federally supported housing" and "advocated a permanent Fair Employment Practices Commission".:59 Shortly after taking office, Kennedy issued Executive Order 10925 in March 1961, requiring government contractors to "consider and recommend additional affirmative steps which should be taken by executive departments and agencies to realize more fully the national policy of nondiscrimination. The contractor will take affirmative action to ensure that applicants are employed, and that employees are treated during employment, without regard to their race, creed, color, or national origin".:60 The order also established the President's Committee on Equal Employment Opportunity (PCEEO), chaired by Vice President Lyndon B. Johnson. Federal contractors who failed to comply or violated the executive order were punished by contract cancellation and the possible debarment from future government contracts. The administration was "not demanding any special preference or treatment or quotas for minorities" but was rather "advocating racially neutral hiring to end job discrimination".:61 Turning to issues of women's rights, Kennedy initiated a Commission on the Status of Women in December 1961. The commission was charged with "examining employment policies and practices of the government and of contractors" with regard to sex.:66
Question: What does PCEEO stand for?

Output: President's Committee on Equal Employment Opportunity

QUES: The Ricketts family acquired a majority interest in the Cubs in 2009, ending the Tribune years. Apparently handcuffed by the Tribune's bankruptcy and the sale of the club to the Ricketts family, the Cubs' quest for a NL Central 3-peat started with notice that there would be less invested into contracts than in previous years. Chicago engaged St. Louis in a see-saw battle for first place into August 2009, but the Cardinals played to a torrid 206 pace that month, designating their rivals to battle in the Wild Card race, from which they were eliminated in the season's final week. The Cubs were plagued by injuries in 2009, and were only able to field their Opening Day starting lineup three times the entire season. Third baseman Aramis Ramirez injured his throwing shoulder in an early May game against the Milwaukee Brewers, sidelining him until early July and forcing journeyman players like Mike Fontenot and Aaron Miles into more prominent roles. Additionally, key players like Derrek Lee (who still managed to hit .306 with 35 HR and 111 RBI that season), Alfonso Soriano and Geovany Soto also nursed nagging injuries. The Cubs posted a winning record (8378) for the third consecutive season, the first time the club had done so since 1972, and a new era of ownership under the Ricketts' family was approved by MLB owners in early October.

Who did Chicago engage in a see-saw battle for first place into August 2009?
What is the answer?
ANS: St. Louis

QUES: The architecture and urbanism of the Classical civilizations such as the Greek and the Roman evolved from civic ideals rather than religious or empirical ones and new building types emerged. Architectural "style" developed in the form of the Classical orders.
What owes its development to the Classical orders?

ANS: Architectural "style"

In many situations it is desirable to consider two group elements the same if they differ by an element of a given subgroup. For example, in D4 above, once a reflection is performed, the square never gets back to the r2 configuration by just applying the rotation operations (and no further reflections), i.e. the rotation operations are irrelevant to the question whether a reflection has been performed. Cosets are used to formalize this insight: a subgroup H defines left and right cosets, which can be thought of as translations of H by arbitrary group elements g. In symbolic terms, the left and right cosets of H containing g are
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When are rotation operations considered?
Ah, so.. unanswerable

Question: Strange matter is a particular form of quark matter, usually thought of as a liquid of up, down, and strange quarks. It is contrasted with nuclear matter, which is a liquid of neutrons and protons (which themselves are built out of up and down quarks), and with non-strange quark matter, which is a quark liquid that contains only up and down quarks. At high enough density, strange matter is expected to be color superconducting. Strange matter is hypothesized to occur in the core of neutron stars, or, more speculatively, as isolated droplets that may vary in size from femtometers (strangelets) to kilometers (quark stars).
Try to answer this question if possible: What kind of core does nuclear matter occur in?
Answer: unanswerable

Input: Read this: Backup and Restore, the backup component of Windows, is deprecated. It still ships with Windows 8 and continues to work on preset schedules, but is pushed to the background and can only be accessed through a Control Panel applet called "Windows 7 File Recovery".:76 Shadow Copy, a component of Windows Explorer that once saved previous versions of changed files, no longer protects local files and folders. It can only access previous versions of shared files stored on a Windows Server computer.:74 The subsystem on which these components worked, however, is still available for other software to use.:74
Question: What does :67 Shadow Copy do?

Output:
unanswerable
