user: Problem: Eton College:

A boy who is late for any division or other appointment may be required to sign "Tardy Book", a register kept in the School Office, between 7.35am and 7.45am, every morning for the duration of his sentence (typically three days). Tardy Book may also be issued for late work. For more serious misdeeds, a boy is summoned from his lessons to the Head Master, or Lower Master if the boy is in the lower two years, to talk personally about his misdeeds. This is known as the "Bill". The most serious misdeeds may result in expulsion, or rustication (suspension). Conversely, should a master be more than 15 minutes late for a class, traditionally the pupils might claim it as a "run" and absent themselves for the rest of its duration.

Who do students meet with if the commit the most serious misdeeds?

Problem: Cinema first appeared in Greece in 1896 but the first actual cine-theatre was opened in 1907. In 1914 the Asty Films Company was founded and the production of long films began. Golfo (Γκόλφω), a well known traditional love story, is considered the first Greek feature film, although there were several minor productions such as newscasts before this. In 1931 Orestis Laskos directed Daphnis and Chloe (Δάφνις και Χλόη), containing the first nude scene in the history of European cinema; it was also the first Greek movie which was played abroad. In 1944 Katina Paxinou was honoured with the Best Supporting Actress Academy Award for For Whom the Bell Tolls.

On October 31, 2013, after outcry from media outlets, including heavy criticism  from Nick Bilton of The New York Times, the FAA announced it will allow airlines to expand the passengers use of portable electronic devices during all phases of flight, but mobile phone calls will still be prohibited. Implementation will vary among airlines. The FAA expects many carriers to show that their planes allow passengers to safely use their devices in airplane mode, gate-to-gate, by the end of 2013. Devices must be held or put in the seat-back pocket during the actual takeoff and landing. Mobile phones must be in airplane mode or with mobile service disabled, with no signal bars displayed, and cannot be used for voice communications due to Federal Communications Commission regulations that prohibit any airborne calls using mobile phones. If an air carrier provides Wi-Fi service during flight, passengers may use it. Short-range Bluetooth accessories, like wireless keyboards, can also be used.
What paper criticized Nick Bilton?

Question: Although Chinese characters in Vietnam are now limited to ceremonial uses, they were once in widespread use. Until the early 20th century, Literary Chinese was used in Vietnam for all official and scholarly writing. Around the 13th century the Nôm script was developed to record folk literature in the Vietnamese language. The script used Chinese characters to represent both borrowed Sino-Vietnamese vocabulary and native words with similar pronunciation or meaning. In addition thousands of new compound characters were created to write Vietnamese words. This process resulted in a highly complex system that was never mastered by more than 5% of the population. Both Literary Chinese and Nôm were replaced in the early 20th century by Vietnamese written with the Latin-based Vietnamese alphabet.
Is there an answer to this question: What were once in widespread use?

Answer: Chinese characters in Vietnam

Mastic asphalt is a type of asphalt which differs from dense graded asphalt (asphalt concrete) in that it has a higher asphalt/bitumen (binder) content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% added asphalt/bitumen. This thermoplastic substance is widely used in the building industry for waterproofing flat roofs and tanking underground. Mastic asphalt is heated to a temperature of 210 °C (410 °F) and is spread in layers to form an impervious barrier about 20 millimeters (0.79 inches) thick.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How is asphalt used in the construction industry?
Ah, so..
