Problem: Arsenal F.C.:

Arsenal fans often refer to themselves as "Gooners", the name derived from the team's nickname, "The Gunners". The fanbase is large and generally loyal, and virtually all home matches sell out; in 2007–08 Arsenal had the second-highest average League attendance for an English club (60,070, which was 99.5% of available capacity), and, as of 2015, the third-highest all-time average attendance. Arsenal have the seventh highest average attendance of European football clubs only behind Borussia Dortmund, FC Barcelona, Manchester United, Real Madrid, Bayern Munich, and Schalke. The club's location, adjoining wealthy areas such as Canonbury and Barnsbury, mixed areas such as Islington, Holloway, Highbury, and the adjacent London Borough of Camden, and largely working-class areas such as Finsbury Park and Stoke Newington, has meant that Arsenal's supporters have come from a variety of social classes.

Which team had the highest attendance in 2015?

A: unanswerable


Problem: Mosaic:

There were two main techniques in Greco-Roman mosaic: opus vermiculatum used tiny tesserae, typically cubes of 4 millimeters or less, and was produced in workshops in relatively small panels which were transported to the site glued to some temporary support. The tiny tesserae allowed very fine detail, and an approach to the illusionism of painting. Often small panels called emblemata were inserted into walls or as the highlights of larger floor-mosaics in coarser work. The normal technique was opus tessellatum, using larger tesserae, which was laid on site. There was a distinct native Italian style using black on a white background, which was no doubt cheaper than fully coloured work.

What was the benefit of using small pieces to create a mosaic?
---
A: very fine detail


Problem: Gramophone record:

Vinyl pressings were made with stampers from master cuts that were electroplated in vacuo by means of gold sputtering. Audio response was claimed out to 8,000 Hz, later 13,000 Hz, using light weight pickups employing jeweled styli. Amplifiers and cutters both using negative feedback were employed thereby improving the range of frequencies cut and lowering distortion levels. Radio transcription producers such as World Broadcasting System and Associated Music Publishers (AMP) were the dominant licensees of the Western Electric wide range system and towards the end of the 1930s were responsible for two-thirds of the total radio transcription business. These recordings use a bass turnover of 300 Hz and a 10,000 Hz rolloff of −8.5 dB.

Who was responsible for 2/3 of all recordings in the 1930s?
---
A: World Broadcasting System and Associated Music Publishers


Problem: Pub:

The restrictions were tightened by the Defence of the Realm Act of August 1914, which, along with the introduction of rationing and the censorship of the press for wartime purposes, restricted pubs' opening hours to 12 noon–2:30 pm and 6:30 pm–9:30 pm. Opening for the full licensed hours was compulsory, and closing time was equally firmly enforced by the police; a landlord might lose his licence for infractions. Pubs were closed under the Act and compensation paid, for example in Pembrokeshire.

What body enforced pubs' closing hours under the Defence of the Realm Act?
---
A:
the police
