Problem: LaserDisc:

In the mid-1980s Lucasfilm pioneered the EditDroid non-linear editing system for film and television based on computer-controlled LaserDisc players. Instead of printing dailies out on film, processed negatives from the day's shoot would be sent to a mastering plant to be assembled from their 10-minute camera elements into 20-minute film segments. These were then mastered onto single-sided blank LaserDiscs, just as a DVD would be burnt at home today, allowing for much easier selection and preparation of an Edit Decision List. In the days before video assist was available in cinematography, this was the only other way a film crew could see their work. The EDL went to the negative cutter who then cut the camera negative accordingly and assembled the finished film. Only 24 EditDroid systems were ever built, even though the ideas and technology are still in use today. Later EditDroid experiments borrowed from hard-drive technology of having multiple discs on the same spindle and added numerous playback heads and numerous electronics to the basic jukebox design so that any point on each of the discs would be accessible within seconds. This eliminated the need for racks and racks of industrial LaserDisc players since EditDroid discs were only single-sided.

How many EditDroid systems were ever built?

Problem: Kanye West:

On November 10, 2007, at approximately 7:35 pm, paramedics responding to an emergency call transported West's mother, Donda West, to the nearby Centinela Freeman Hospital in Marina del Rey, California. She was unresponsive in the emergency room, and after resuscitation attempts, doctors pronounced her dead at approximately 8:30 pm, at age 58. The Los Angeles County coroner's office said in January 2008 that West had died of heart disease while suffering "multiple post-operative factors" after plastic surgery. She had undergone liposuction and breast reduction. Beverly Hills plastic surgeon Andre Aboolian had refused to do the surgery because West had a health condition that placed her at risk for a heart attack. Aboolian referred her to an internist to investigate her cardiac issue. She never met with the doctor recommended by Aboolian and had the procedures performed by a third doctor, Jan Adams.

What was the name of the doctor who performed the surgery that ended up killing Donda West?

A: Jan Adams

Problem: Aspirated consonant:

Standard Chinese (Mandarin) has stops and affricates distinguished by aspiration: for instance, /t t/, /ts ts/. In pinyin, tenuis stops are written with letters that represent voiced consonants in English, and aspirated stops with letters that represent voiceless consonants. Thus d represents /t/, and t represents /t/.

In pinyin, tenuis consonants are written how?

A: unanswerable

Problem: Time:

Time appears to have a directionthe past lies behind, fixed and immutable, while the future lies ahead and is not necessarily fixed. Yet for the most part the laws of physics do not specify an arrow of time, and allow any process to proceed both forward and in reverse. This is generally a consequence of time being modeled by a parameter in the system being analyzed, where there is no "proper time": the direction of the arrow of time is sometimes arbitrary. Examples of this include the Second law of thermodynamics, which states that entropy must increase over time (see Entropy); the cosmological arrow of time, which points away from the Big Bang, CPT symmetry, and the radiative arrow of time, caused by light only traveling forwards in time (see light cone). In particle physics, the violation of CP symmetry implies that there should be a small counterbalancing time asymmetry to preserve CPT symmetry as stated above. The standard description of measurement in quantum mechanics is also time asymmetric (see Measurement in quantum mechanics).

The direction of the arrow of time is sometimes what?

A:
arbitrary
