Input: Botany
Judging relationships based on shared characters requires care, since plants may resemble one another through convergent evolution in which characters have arisen independently. Some euphorbias have leafless, rounded bodies adapted to water conservation similar to those of globular cacti, but characters such as the structure of their flowers make it clear that the two groups are not closely related. The cladistic method takes a systematic approach to characters, distinguishing between those that carry no information about shared evolutionary history such as those evolved separately in different groups (homoplasies) or those left over from ancestors (plesiomorphies) and derived characters, which have been passed down from innovations in a shared ancestor (apomorphies). Only derived characters, such as the spine-producing areoles of cacti, provide evidence for descent from a common ancestor. The results of cladistic analyses are expressed as cladograms: tree-like diagrams showing the pattern of evolutionary branching and descent.

Why might two plants be similar but not actually be in the same group?
Output: convergent evolution

Input: Article: With its growing popularity, professional wrestling has attracted attention as a subject of serious academic study and journalistic criticism. Many courses, theses, essays, and dissertations have analyzed wrestling's conventions, content, and its role in modern society. It is often included as part of studies on theatre, sociology, performance, and media. The Massachusetts Institute of Technology developed a course of study on the cultural significance of professional wrestling, and anthropologist Heather Levi has written an ethnography about the culture of lucha libre in Mexico.

Now answer this question: What college has a course about the cultural impact of wrestling?

Output: Massachusetts Institute of Technology

Article: Pentecostalism eventually spawned hundreds of new denominations, including large groups such as the Assemblies of God and the Church of God in Christ, both in the United States and elsewhere. There are over 279 million Pentecostals worldwide, and the movement is growing in many parts of the world, especially the global South. Since the 1960s, Pentecostalism has increasingly gained acceptance from other Christian traditions, and Pentecostal beliefs concerning Spirit baptism and spiritual gifts have been embraced by non-Pentecostal Christians in Protestant and Catholic churches through the Charismatic Movement. Together, Pentecostal and Charismatic Christianity numbers over 500 million adherents.

Question: What movement has caused non-Pentecostal churches to accept some Pentecostal beliefs?
Ans: Charismatic

Here is a question about this article: In 2003, Nintendo announced that a new The Legend of Zelda game was in the works for the GameCube by the same team that had created the cel-shaded The Wind Waker. At the following year's Game Developers Conference, director Eiji Aonuma unintentionally revealed that the game's sequel was in development under the working title The Wind Waker 2; it was set to use a similar graphical style to that of its predecessor. Nintendo of America told Aonuma that North American sales of The Wind Waker were sluggish because its cartoon appearance created the impression that the game was designed for a young audience. Concerned that the sequel would have the same problem, Aonuma expressed to producer Shigeru Miyamoto that he wanted to create a realistic Zelda game that would appeal to the North American market. Miyamoto, hesitant about solely changing the game's presentation, suggested the team's focus should instead be on coming up with gameplay innovations. He advised that Aonuma should start by doing what could not be done in Ocarina of Time, particularly horseback combat.[l]
What is the answer to this question: What was one feature that could not be implemented in Ocarina of Time?
****
So... horseback combat

The problem: Answer a question about this article:
While Old Czech had a basic alphabet from which a general set of orthographical correspondences was drawn, it did not have a standard orthography. It also contained a number of sound clusters which no longer exist; allowing e (/j/) after soft consonants, which has since shifted to e (//), and allowing complex consonant clusters to be pronounced all at once rather than syllabically. A phonological phenomenon, Havlik's law (which began in Proto-Slavic and took various forms in other Slavic languages), appeared in Old Czech; counting backwards from the end of a clause, every odd-numbered yer was vocalized as a vowel, while the other yers disappeared.
What type of phenomenon is Havlik's law?
****
The answer: phonological

In 2008, the High Court in South Africa ruled that Chinese South Africans who were residents during the apartheid era (and their descendants) are to be reclassified as "Black people," solely for the purposes of accessing affirmative action benefits, because they were also "disadvantaged" by racial discrimination. Chinese people who arrived in the country after the end of apartheid do not qualify for such benefits.
Why was this classification made?
****
The answer:
solely for the purposes of accessing affirmative action benefits
