The problem: Answer a question about this article:
Symbiosis played a major role in the co-evolution of flowering plants and the animals that pollinate them. Many plants that are pollinated by insects, bats, or birds have highly specialized flowers modified to promote pollination by a specific pollinator that is also correspondingly adapted. The first flowering plants in the fossil record had relatively simple flowers. Adaptive speciation quickly gave rise to many diverse groups of plants, and, at the same time, corresponding speciation occurred in certain insect groups. Some groups of plants developed nectar and large sticky pollen, while insects evolved more specialized morphologies to access and collect these rich food sources. In some taxa of plants and insects the relationship has become dependent, where the plant species can only be pollinated by one species of insect.
How big a part did symbiosis have in the development of flowering plants and their pollinators?
****
The answer: a major role


Problem: Please answer a question about the following article about Chicago Cubs:
Despite the fact that the Cubs had won 89 games, this fallout was decidedly unlovable, as the Cubs traded superstar Sammy Sosa after he had left the season's final game early and then lied about it publicly. Already a controversial figure in the clubhouse after his corked-bat incident, Sammy's actions alienated much of his once strong fan base as well as the few teammates still on good terms with him, (many teammates grew tired of Sosa playing loud salsa music in the locker room) and possibly tarnished his place in Cubs' lore for years to come. The disappointing season also saw fans start to become frustrated with the constant injuries to ace pitchers Mark Prior and Kerry Wood. Additionally, the '04 season led to the departure of popular commentator Steve Stone, who had become increasingly critical of management during broadcasts and was verbally attacked by reliever Kent Mercker. Things were no better in 2005, despite a career year from first baseman Derrek Lee and the emergence of closer Ryan Dempster. The club struggled and suffered more key injuries, only managing to win 79 games after being picked by many to be a serious contender for the N.L. pennant. In 2006, bottom fell out as the Cubs finished 66–96, last in the NL Central.
Who did the Cubs trade after leaving the final game early and lieing about it?
A: Sammy Sosa


Question: Read this and answer the question

The modern pharmaceutical industry traces its roots to two sources. The first of these were local apothecaries that expanded from their traditional role distributing botanical drugs such as morphine and quinine to wholesale manufacture in the mid 1800s. Rational drug discovery from plants started particularly with the isolation of morphine, analgesic and sleep-inducing agent from opium, by the German apothecary assistant Friedrich Sertürner, who named the compound after the Greek god of dreams, Morpheus. Multinational corporations including Merck, Hoffman-La Roche, Burroughs-Wellcome (now part of Glaxo Smith Kline), Abbott Laboratories, Eli Lilly and Upjohn (now part of Pfizer) began as local apothecary shops in the mid-1800s. By the late 1880s, German dye manufacturers had perfected the purification of individual organic compounds from coal tar and other mineral sources and had also established rudimentary methods in organic chemical synthesis. The development of synthetic chemical methods allowed scientists to systematically vary the structure of chemical substances, and growth in the emerging science of pharmacology expanded their ability to evaluate the biological effects of these structural changes.

Where were was Morphine extracted from?
Answer: opium


Problem: Switzerland lies between latitudes 45° and 48° N, and longitudes 5° and 11° E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss Plateau or Central Plateau, and the Jura mountains on the west. The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area. The majority of the Swiss population live in the Swiss Plateau. Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres (410 sq mi). From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhône, which flow in the four cardinal directions into the whole of Europe. The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva (also called le Lac Léman in French), Lake Constance (known as Bodensee in German) and Lake Maggiore. Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water. Lakes and glaciers cover about 6% of the national territory. The largest lake is Lake Geneva, in western Switzerland shared with France. The Rhône is both the main source and outflow of Lake Geneva. Lake Constance is the second largest Swiss lake and, like the Lake Geneva, an intermediate step by the Rhine at the border to Austria and Germany. While the Rhône flows into the Mediterranean Sea at the French Camarque region and the Rhine flows into the North Sea at Rotterdam in the Netherlands, about 1000 km apart, both springs are only about 22 km apart from each other in the Swiss Alps.
Which basic topographical area is in western Switzerland?
The answer is the following: Jura mountains


The first BeiDou system, officially called the BeiDou Satellite Navigation Experimental System (simplified Chinese: 北斗卫星导航试验系统; traditional Chinese: 北斗衛星導航試驗系統; pinyin: Běidǒu wèixīng dǎoháng shìyàn xìtǒng) and also known as BeiDou-1, consists of three satellites and offers limited coverage and applications. It has been offering navigation services, mainly for customers in China and neighboring regions, since 2000.
Who does the BeiDou-1 operate for?
mainly for customers in China and neighboring regions


Here is a question about this article: 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 is the answer to this question: What percentage of the immigrants were born in Switzerland as of 2012?
****
So...
one fifth
