Input: Read this: Since the 1970s, an important focus of study has been the ozone layer in the atmosphere above Antarctica. In 1985, three British scientists working on data they had gathered at Halley Station on the Brunt Ice Shelf discovered the existence of a hole in this layer. It was eventually determined that the destruction of the ozone was caused by chlorofluorocarbons (CFCs) emitted by human products. With the ban of CFCs in the Montreal Protocol of 1989, climate projections indicate that the ozone layer will return to 1980 levels between 2050 and 2070.
Question: When did scientists discover the hole in the ozone layer?

Output: 1985

QUES: A database built with one DBMS is not portable to another DBMS (i.e., the other DBMS cannot run it). However, in some situations it is desirable to move, migrate a database from one DBMS to another. The reasons are primarily economical (different DBMSs may have different total costs of ownership or TCOs), functional, and operational (different DBMSs may have different capabilities). The migration involves the database's transformation from one DBMS type to another. The transformation should maintain (if possible) the database related application (i.e., all related application programs) intact. Thus, the database's conceptual and external architectural levels should be maintained in the transformation. It may be desired that also some aspects of the architecture internal level are maintained. A complex or large database migration may be a complicated and costly (one-time) project by itself, which should be factored into the decision to migrate. This in spite of the fact that tools may exist to help migration between specific DBMSs. Typically a DBMS vendor provides tools to help importing databases from other popular DBMSs.

How can a DBMS database migration be made easier?
What is the answer?
ANS: vendor provides tools

QUES: As a consequence of his heart attack, Eisenhower developed a left ventricular aneurysm, which was in turn the cause of a mild stroke on November 25, 1957. This incident occurred during a cabinet meeting when Eisenhower suddenly found himself unable to speak or move his right hand. The stroke had caused an aphasia. The president also suffered from Crohn's disease, chronic inflammatory condition of the intestine, which necessitated surgery for a bowel obstruction on June 9, 1956. To treat the intestinal block, surgeons bypassed about ten inches of his small intestine. His scheduled meeting with Indian Prime Minister Jawaharlal Nehru was postponed so he could recover from surgery at his farm in Gettysburg, Pennsylvania. He was still recovering from this operation during the Suez Crisis. Eisenhower's health issues forced him to give up smoking and make some changes to his dietary habits, but he still indulged in alcohol. During a visit to England he complained of dizziness and had to have his blood pressure checked on August 29, 1959; however, before dinner at Chequers on the next day his doctor General Howard Snyder recalled Eisenhower "drank several gin-and-tonics, and one or two gins on the rocks ... three or four wines with the dinner".
What couldn't Eisenhower move as a result of his stroke?

ANS: right hand

Throughout most of his career, Athanasius had many detractors. Classical scholar Timothy Barnes relates contemporary allegations against Athanasius: from defiling an altar, to selling Church grain that had been meant to feed the poor for his own personal gain, and even violence and murder to suppress dissent. Athanasius used "Arian" to describe both followers of Arius, and as a derogatory polemical term for Christians who disagreed with his formulation of the Trinity. Athanasius called many of his opponents "Arian", except for Miletus.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who liked Athanasius?
Ah, so.. unanswerable

Question: United States President Barack Obama and key advisers introduced a series of regulatory proposals in June 2009. The proposals address consumer protection, executive pay, bank financial cushions or capital requirements, expanded regulation of the shadow banking system and derivatives, and enhanced authority for the Federal Reserve to safely wind-down systemically important institutions, among others. In January 2010, Obama proposed additional regulations limiting the ability of banks to engage in proprietary trading. The proposals were dubbed "The Volcker Rule", in recognition of Paul Volcker, who has publicly argued for the proposed changes.
Try to answer this question if possible: Regulations were proposed by Obama in January 2010 to limit the ability of banks to engage in which type trading?
Answer: proprietary

Input: Read this: The Archivist of the United States is the chief official overseeing the operation of the National Archives and Records Administration. The Archivist not only maintains the official documentation of the passage of amendments to the U.S. Constitution by state legislatures, but has the authority to declare when the constitutional threshold for passage has been reached, and therefore when an act has become an amendment.
Question: What is the official that oversees the operation of NARA?

Output:
The Archivist
