Problem: In 2012, resident foreigners made up 23.3% of the population. Most of these (64%) were from European Union or EFTA countries. Italians were the largest single group of foreigners with 15.6% of total foreign population. They were closely followed by Germans (15.2%), immigrants from Portugal (12.7%), France (5.6%), Serbia (5.3%), Turkey (3.8%), Spain (3.7%), and Austria (2%). Immigrants from Sri Lanka, most of them former Tamil refugees, were the largest group among people of Asian origin (6.3%). Additionally, the figures from 2012 show that 34.7% of the permanent resident population aged 15 or over in Switzerland, i.e. 2,335,000 persons, had an immigrant background. A third of this population (853,000) held Swiss citizenship. Four fifths of persons with an immigration background were themselves immigrants (first generation foreigners and native-born and naturalised Swiss citizens), whereas one fifth were born in Switzerland (second generation foreigners and native-born and naturalised Swiss citizens). In the 2000s, domestic and international institutions expressed concern about what they perceived as an increase in xenophobia, particularly in some political campaigns. In reply to one critical report the Federal Council noted that "racism unfortunately is present in Switzerland", but stated that the high proportion of foreign citizens in the country, as well as the generally unproblematic integration of foreigners", underlined Switzerland's openness.
What percentage of the immigrants were born in Switzerland as of 2012?
The answer is the following: one fifth

Problem: Because of many technical restrictions in computing and also because of the unavailability of Cyrillic keyboards abroad, Russian is often transliterated using the Latin alphabet. For example, мороз ('frost') is transliterated moroz, and мышь ('mouse'), mysh or myš'. Once commonly used by the majority of those living outside Russia, transliteration is being used less frequently by Russian-speaking typists in favor of the extension of Unicode character encoding, which fully incorporates the Russian alphabet. Free programs leveraging this Unicode extension are available which allow users to type Russian characters, even on Western 'QWERTY' keyboards.
What is 'moroz' a transliteration of?
The answer is the following: мороз

Problem: On election day (6 May 2010), The Sun urged its readers to vote for David Cameron's "modern and positive" Conservatives in order to save Britain from "disaster" which the paper thought the country would face if the Labour government was re-elected. The election ended in the first hung parliament after an election for 36 years, with the Tories gaining the most seats and votes but being 20 seats short of an overall majority. They finally came to power on 11 May when Gordon Brown stepped down as prime minister, paving the way for David Cameron to become prime minister by forming a coalition with the Liberal Democrats.
What did The Sun fear would result from election of the Labour Party?
The answer is the following: disaster

Problem: The number of species invasions has been on the rise at least since the beginning of the 1900s. Species are increasingly being moved by humans (on purpose and accidentally). In some cases the invaders are causing drastic changes and damage to their new habitats (e.g.: zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. Others report confounding evidence that occasionally suggest that species-rich communities harbor many native and exotic species simultaneously while some say that diverse ecosystems are more resilient and resist invasive plants and animals. An important question is, "do invasive species cause extinctions?" Many studies cite effects of invasive species on natives, but not extinctions. Invasive species seem to increase local (i.e.: alpha diversity) diversity, which decreases turnover of diversity (i.e.: beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Extirpation, population decline, and homogenization of regional biodiversity are much more common. Human activities have frequently been the cause of invasive species circumventing their barriers, by introducing them for food and other purposes. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range.
What invaders are causing changes along the North American Atlantic coast?
The answer is the following:
lion fish
