Input: Read this: 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.
Question: In order to merge, what must the database maintain?

Output: database related application

Input: Read this: On 3 December 1963, US President Lyndon B. Johnson posthumously awarded him the Presidential Medal of Freedom, the United States' highest civilian award, in recognition of the good relationship between Pope John XXIII and the United States of America. In his speech on 6 December 1963, Johnson said: "I have also determined to confer the Presidential Medal of Freedom posthumously on another noble man whose death we mourned 6 months ago: His Holiness, Pope John XXIII. He was a man of simple origins, of simple faith, of simple charity. In this exalted office he was still the gentle pastor. He believed in discussion and persuasion. He profoundly respected the dignity of man. He gave the world immortal statements of the rights of man, of the obligations of men to each other, of their duty to strive for a world community in which all can live in peace and fraternal friendship. His goodness reached across temporal boundaries to warm the hearts of men of all nations and of all faiths".
Question: What is the Presidential Medal Freedom?

Output: the United States' highest civilian award

Input: Read this: In July 2015, Eton accidentally sent emails to 400 prospective students, offering them conditional entrance to the school in September 2017. The email was intended for nine students, but an IT glitch caused the email to be sent to 400 additional families, who didn't necessarily have a place. In response, the school issued the following statement: "This error was discovered within minutes and each family was immediately contacted to notify them that it should be disregarded and to apologise. We take this type of incident very seriously indeed and so a thorough investigation, overseen by the headmaster Tony Little and led by the tutor for admissions, is being carried out to find out exactly what went wrong and ensure it cannot happen again. Eton College offers its sincere apologies to those boys concerned and their families. We deeply regret the confusion and upset this must have caused."
Question: For how many students was the email mistake originally intended?

Output: nine

Input: Read this: Indic scripts such as Tamil and Devanagari are each allocated only 128 code points, matching the ISCII standard. The correct rendering of Unicode Indic text requires transforming the stored logical order characters into visual order and the forming of ligatures (aka conjuncts) out of components. Some local scholars argued in favor of assignments of Unicode code points to these ligatures, going against the practice for other writing systems, though Unicode contains some Arabic and other ligatures for backward compatibility purposes only. Encoding of any new ligatures in Unicode will not happen, in part because the set of ligatures is font-dependent, and Unicode is an encoding independent of font variations. The same kind of issue arose for Tibetan script[citation needed] (the Chinese National Standard organization failed to achieve a similar change).
Question: Who argued Indic scripts should follow the practice of other writing systems?

Output:
unanswerable
