The problem: Answer a question about this article:
Her debut single, "Crazy in Love" was named VH1's "Greatest Song of the 2000s", NME's "Best Track of the 00s" and "Pop Song of the Century", considered by Rolling Stone to be one of the 500 greatest songs of all time, earned two Grammy Awards and is one of the best-selling singles of all time at around 8 million copies. The music video for "Single Ladies (Put a Ring on It)", which achieved fame for its intricate choreography and its deployment of jazz hands, was credited by the Toronto Star as having started the "first major dance craze of both the new millennium and the Internet", triggering a number of parodies of the dance choreography and a legion of amateur imitators on YouTube. In 2013, Drake released a single titled "Girls Love Beyonce", which featured an interpolation from Destiny Child's "Say My Name" and discussed his relationship with women. In January 2012, research scientist Bryan Lessard named Scaptia beyonceae, a species of horse fly found in Northern Queensland, Australia after Beyonce due to the fly's unique golden hairs on its abdomen. In July 2014, a Beyonce exhibit was introduced into the "Legends of Rock" section of the Rock and Roll Hall of Fame. The black leotard from the "Single Ladies" video and her outfit from the Super Bowl half time performance are among several pieces housed at the museum.
How many Grammy awards did Crazy in Love get?
****
The answer: earned two Grammy Awards

Problem: Please answer a question about the following article about Symbiosis:
Symbiotic relationships include those associations in which one organism lives on another (ectosymbiosis, such as mistletoe), or where one partner lives inside the other (endosymbiosis, such as lactobacilli and other bacteria in humans or Symbiodinium in corals). Symbiosis is also classified by physical attachment of the organisms; symbiosis in which the organisms have bodily union is called conjunctive symbiosis, and symbiosis in which they are not in union is called disjunctive symbiosis.
What is an example of ectosymbiosis?
A: mistletoe

The original Latin word "universitas" refers in general to "a number of persons associated into one body, a society, company, community, guild, corporation, etc." At the time of the emergence of urban town life and medieval guilds, specialised "associations of students and teachers with collective legal rights usually guaranteed by charters issued by princes, prelates, or the towns in which they were located" came to be denominated by this general term. Like other guilds, they were self-regulating and determined the qualifications of their members.

From what language does Universitas come from?
Answer: Latin

Problem: Of numerous relationships between male slaveholders, overseers, or master's sons and women slaves, the most notable is likely that of President Thomas Jefferson with his slave Sally Hemings. As noted in the 2012 collaborative Smithsonian-Monticello exhibit, Slavery at Monticello: The Paradox of Liberty, Jefferson, then a widower, took Hemings as his concubine for nearly 40 years. They had six children of record; four Hemings children survived into adulthood, and he freed them all, among the very few slaves he freed. Two were allowed to "escape" to the North in 1822, and two were granted freedom by his will upon his death in 1826. Seven-eighths white by ancestry, all four of his Hemings children moved to northern states as adults; three of the four entered the white community, and all their descendants identified as white. Of the descendants of Madison Hemings, who continued to identify as black, some in future generations eventually identified as white and "married out", while others continued to identify as African American. It was socially advantageous for the Hemings children to identify as white, in keeping with their appearance and the majority proportion of their ancestry. Although born into slavery, the Hemings children were legally white under Virginia law of the time.
President Thomas Jefferson had a relationship with who?
The answer is the following: Sally Hemings

Many beers are sold in cans, though there is considerable variation in the proportion between different countries. In Sweden in 2001, 63.9% of beer was sold in cans. People either drink from the can or pour the beer into a glass. A technology developed by Crown Holdings for the 2010 FIFA World Cup is the 'full aperture' can, so named because the entire lid is removed during the opening process, turning the can into a drinking cup. Cans protect the beer from light (thereby preventing "skunked" beer) and have a seal less prone to leaking over time than bottles. Cans were initially viewed as a technological breakthrough for maintaining the quality of a beer, then became commonly associated with less expensive, mass-produced beers, even though the quality of storage in cans is much like bottles. Plastic (PET) bottles are used by some breweries.
What percentage of beer was sold in cans in Sweden in 2001?
63.9%

Here is a question about this article: 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 is the answer to this question: What invaders are causing changes in the Great Lakes region?
****
So...
zebra mussels and the emerald ash borer
