Beer was spread through Europe by Germanic and Celtic tribes as far back as 3000 BC, and it was mainly brewed on a domestic scale. The product that the early Europeans drank might not be recognised as beer by most people today. Alongside the basic starch source, the early European beers might contain fruits, honey, numerous types of plants, spices and other substances such as narcotic herbs. What they did not contain was hops, as that was a later addition, first mentioned in Europe around 822 by a Carolingian Abbot and again in 1067 by Abbess Hildegard of Bingen.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): On what continent were hops first added to beer?
Ah, so.. Europe

Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.

Ah, so.. unanswerable

In December 2009, campaigners in the UK called on two leading high street retailers to stop selling clothes made with cotton which may have been picked by children. Anti-Slavery International and the Environmental Justice Foundation (EJF) accused H&M and Zara of using cotton suppliers in Bangladesh. It is also suspected that many of their raw materials originates from Uzbekistan, where children aged 10 are forced to work in the fields. The activists were calling to ban the use of Uzbek cotton and implement a "track and trace" systems to guarantee an ethical responsible source of the material.

Ah, so..
