Problem: Arsenal F.C.:

Arsenal's home colours have been the inspiration for at least three other clubs. In 1909, Sparta Prague adopted a dark red kit like the one Arsenal wore at the time; in 1938, Hibernian adopted the design of the Arsenal shirt sleeves in their own green and white strip. In 1920, Sporting Clube de Braga's manager returned from a game at Highbury and changed his team's green kit to a duplicate of Arsenal's red with white sleeves and shorts, giving rise to the team's nickname of Os Arsenalistas. These teams still wear those designs to this day.

By coping the Arsenal team kit exactly, what nickname was given to Sporting Clube de Braga?

A: Os Arsenalistas

Problem: Transistor:

Discrete transistors are individually packaged transistors. Transistors come in many different semiconductor packages (see image). The two main categories are through-hole (or leaded), and surface-mount, also known as surface-mount device (SMD). The ball grid array (BGA) is the latest surface-mount package (currently only for large integrated circuits). It has solder "balls" on the underside in place of leads. Because they are smaller and have shorter interconnections, SMDs have better high-frequency characteristics but lower power rating.

What is a discrete transistor?

Problem: Windows 8:

In February 2014, Bloomberg reported that Microsoft would be lowering the price of Windows 8 licenses by 70% for devices that retail under US$250; alongside the announcement that an update to the operating system would allow OEMs to produce devices with as little as 1 GB of RAM and 16 GB of storage, critics felt that these changes would help Windows compete against Linux-based devices in the low-end market, particularly those running Chrome OS. Microsoft had similarly cut the price of Windows XP licenses to compete against the early waves of Linux-based netbooks. Reports also indicated that Microsoft was planning to offer cheaper Windows 8 licenses to OEMs in exchange for setting Internet Explorer's default search engine to Bing. Some media outlets falsely reported that the SKU associated with this plan, "Windows 8.1 with Bing", was a variant which would be a free or low-cost version of Windows 8 for consumers using older versions of Windows. On April 2, 2014, Microsoft ultimately announced that it would be removing license fees entirely for devices with screens smaller than 9 inches, and officially confirmed the rumored "Windows 8.1 with Bing" OEM SKU on May 23, 2014.

When did Microsoft remove license fees on device screens less than 8 inches?

A: unanswerable

Problem: Alps:

Human interference has nearly exterminated the trees in many areas, and, except for the beech forests of the Austrian Alps, forests of deciduous trees are rarely found after the extreme deforestation between the 17th and 19th centuries. The vegetation has changed since the second half of the 20th century, as the high alpine meadows cease to be harvested for hay or used for grazing which eventually might result in a regrowth of forest. In some areas the modern practice of building ski runs by mechanical means has destroyed the underlying tundra from which the plant life cannot recover during the non-skiing months, whereas areas that still practice a natural piste type of ski slope building preserve the fragile underlayers.

What has changed since the second half of the 20th century?
