Problem: ASCII:

Code 127 is officially named "delete" but the Teletype label was "rubout". Since the original standard did not give detailed interpretation for most control codes, interpretations of this code varied. The original Teletype meaning, and the intent of the standard, was to make it an ignored character, the same as NUL (all zeroes). This was useful specifically for paper tape, because punching the all-ones bit pattern on top of an existing mark would obliterate it. Tapes designed to be "hand edited" could even be produced with spaces of extra NULs (blank tape) so that a block of characters could be "rubbed out" and then replacements put into the empty space.

What happened to replacements of control codes?

Problem: Incandescent light bulb:

Lamps designed for different voltages have different luminous efficacy. For example, a 100-watt, 120-volt lamp will produce about 17.1 lumens per watt. A lamp with the same rated lifetime but designed for 230 V would produce only around 12.8 lumens per watt, and a similar lamp designed for 30 volts (train lighting) would produce as much as 19.8 lumens per watt. Lower voltage lamps have a thicker filament, for the same power rating. They can run hotter for the same lifetime before the filament evaporates.

How many lumens per watt does a typical 100-watt, 120-volt lamp produce?
---
A: 17.1 lumens per watt


Problem: Copyright infringement:

In Europe, the copyright infringement case Public Relations Consultants Association Ltd v Newspaper Licensing Agency Ltd had two prongs; one concerned whether a news aggregator service infringed the copyright of the news generators; the other concerned whether the temporary web cache created by the web browser of a consumer of the aggregator's service, also infringed the copyright of the news generators. The first prong was decided in favor of the news generators; in June 2014 the second prong was decided by the Court of Justice of the European Union (CJEU), which ruled that the temporary web cache of consumers of the aggregator did not infringe the copyright of the news generators.

Whose copyright were news aggregators infringing on?
---
A: news generators


Problem: Bermuda:

The first known European explorer to reach Bermuda was Spanish sea captain Juan de Bermúdez in 1503, after whom the islands are named. He claimed the apparently uninhabited islands for the Spanish Empire. Paying two visits to the archipelago, Bermúdez never landed on the islands, but did create a recognisable map of the archipelago. Shipwrecked Portuguese mariners are now thought to have been responsible for the 1543 inscription in Portuguese Rock (previously called Spanish Rock). Subsequent Spanish or other European parties are believed to have released pigs there, which had become feral and abundant on the island by the time European settlement began. In 1609, the English Virginia Company, which had established Jamestown in Virginia (a term originally applied to all of the North American continent) two years earlier, permanently settled Bermuda in the aftermath of a hurricane, when the crew and passengers of the Sea Venture steered the ship onto the surrounding reef to prevent its sinking, then landed ashore.

Who settled in Jamestown in 1609?
