Problem: Windows 8:

Windows Explorer, which has been renamed File Explorer, now includes a ribbon in place of the command bar. File operation dialog boxes have been updated to provide more detailed statistics, the ability to pause file transfers, and improvements in the ability to manage conflicts when copying files. A new "File History" function allows incremental revisions of files to be backed up to and restored from a secondary storage device, while Storage Spaces allows users to combine different sized hard disks into virtual drives and specify mirroring, parity, or no redundancy on a folder-by-folder basis.

What did the update of operation dalog boxes help with?

A: provide more detailed statistics, the ability to pause file transfers, and improvements in the ability to manage conflicts when copying files

Problem: Classical music:

Historically, major professional orchestras have been mostly or entirely composed of male musicians. Some of the earliest cases of women being hired in professional orchestras was in the position of harpist. The Vienna Philharmonic, for example, did not accept women to permanent membership until 1997, far later than the other orchestras ranked among the world's top five by Gramophone in 2008. The last major orchestra to appoint a woman to a permanent position was the Berlin Philharmonic. As late as February 1996, the Vienna Philharmonic's principal flute, Dieter Flury, told Westdeutscher Rundfunk that accepting women would be "gambling with the emotional unity (emotionelle Geschlossenheit) that this organism currently has". In April 1996, the orchestra's press secretary wrote that "compensating for the expected leaves of absence" of maternity leave would be a problem.

What year did the Vienna Philharmonic first accept women?

A: 1997

Problem: Database:

The conceptual view provides a level of indirection between internal and external. On one hand it provides a common view of the database, independent of different external view structures, and on the other hand it abstracts away details of how the data are stored or managed (internal level). In principle every level, and even every external view, can be presented by a different data model. In practice usually a given DBMS uses the same data model for both the external and the conceptual levels (e.g., relational model). The internal level, which is hidden inside the DBMS and depends on its implementation, requires a different level of detail and uses its own types of data structure types.

What view can't be presented by a different data model?
