Problem: Eton College:

The opposite of a Show Up is a "Rip". This is for sub-standard work, which is sometimes torn at the top of the page/sheet and must be submitted to the boy's housemaster for signature. Boys who accumulate rips are liable to be given a "White Ticket", which must be signed by all his teachers and may be accompanied by other punishments, usually involving doing domestic chores or writing lines. In recent times,[when?] a milder form of the rip, 'sign for information', colloquially known as an "info", has been introduced, which must also be signed by the boy's housemaster and tutor.

Who must sign a White Ticket?
---
A: all his teachers

Problem: Alexander Graham Bell:

In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.

What was the primary motivation for not building new telegraph lines?
---
A: cost

Problem: Infrared:

Infrared reflectography (fr; it; es), as called by art conservators, can be applied to paintings to reveal underlying layers in a completely non-destructive manner, in particular the underdrawing or outline drawn by the artist as a guide. This often reveals the artist's use of carbon black, which shows up well in reflectograms, as long as it has not also been used in the ground underlying the whole painting. Art conservators are looking to see whether the visible layers of paint differ from the underdrawing or layers in between such alterations are called pentimenti when made by the original artist. This is very useful information in deciding whether a painting is the prime version by the original artist or a copy, and whether it has been altered by over-enthusiastic restoration work. In general, the more pentimenti the more likely a painting is to be the prime version. It also gives useful insights into working practices.

What painting technique is used to reveal working practices?
---
A: unanswerable

Problem: Macintosh:

In 1985, the combination of the Mac, Apple's LaserWriter printer, and Mac-specific software like Boston Software's MacPublisher and Aldus PageMaker enabled users to design, preview, and print page layouts complete with text and graphicsan activity to become known as desktop publishing. Initially, desktop publishing was unique to the Macintosh, but eventually became available for other platforms. Later, applications such as Macromedia FreeHand, QuarkXPress, and Adobe's Photoshop and Illustrator strengthened the Mac's position as a graphics computer and helped to expand the emerging desktop publishing market.

What company was desktop publishing unique to at it's beginning?
---
A:
Macintosh
