Problem: In 1986, Nintendo released the Famicom Disk System (FDS) in Japan, a type of floppy drive that uses a single-sided, proprietary 5 cm (2") disk and plugs into the cartridge port. It contains RAM for the game to load into and an extra single-cycle wavetable-lookup sound chip. The disks were originally obtained from kiosks in malls and other public places where buyers could select a title and have it written to the disk. This process would cost less than cartridges and users could take the disk back to a vending booth and have it rewritten with a new game. The disks were used both for storing the game and saving progress and total capacity was 128k (64k per side).
What were the storage disks used for?
The answer is the following: storing the game and saving progress

Problem: Beyonce and her mother introduced House of Dereon, a contemporary women's fashion line, in 2005.

The collection features sportswear, denim offerings with fur, outerwear and accessories that include handbags and footwear, and are available at department and specialty stores across the US and Canada.
When did Beyonce and her mother start Dereon?
The answer is the following: 2005

Problem: Notably, a statute does not disappear automatically merely because it has been found unconstitutional; it must be deleted by a subsequent statute. Many federal and state statutes have remained on the books for decades after they were ruled to be unconstitutional. However, under the principle of stare decisis, no sensible lower court will enforce an unconstitutional statute, and any court that does so will be reversed by the Supreme Court. Conversely, any court that refuses to enforce a constitutional statute (where such constitutionality has been expressly established in prior cases) will risk reversal by the Supreme Court.
What happens when an unconstitutional statute remains on the books?
The answer is the following: no sensible lower court will enforce

Problem: In 1950, Hayek left the London School of Economics for the University of Chicago, where he became a professor in the Committee on Social Thought. Hayek's salary was funded not by the university, but by an outside foundation. University of Chicago President Robert Hutchins was in the midst of a war with the U. of Chicago faculty over departmental autonomy and control, and Hayek got caught in the middle of that battle. Hutchins had been attempting to force all departments to adopt the neo-Thomist Great Books program of Mortimer Adler, and the U. of Chicago economists were sick of Hutchins' meddling. As the result the Economics department rejected Hutchins' pressure to hire Hayek, and Hayek became a part of the new Committee on Social Thought.
Why did the economics department turn down Hayek's employment?
The answer is the following:
sick of Hutchins' meddling
