input question: Question: "What contains hemoglobin?" Context: "In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin." Answer:???
output answer: red blood cells

Question: "What gave Madonna the reputation of a sexual renegade?" Context: "In September 1993, Madonna embarked on The Girlie Show World Tour, in which she dressed as a whip-cracking dominatrix surrounded by topless dancers. In Puerto Rico she rubbed the island's flag between her legs on stage, resulting in outrage among the audience. In March 1994, she appeared as a guest on the Late Show with David Letterman, using profanity that required censorship on television, and handing Letterman a pair of her panties and asking him to smell it. The releases of her sexually explicit films, albums and book, and the aggressive appearance on Letterman all made critics question Madonna as a sexual renegade. Critics and fans reacted negatively, who commented that "she had gone too far" and that her career was over." Answer:
----
Answer: The releases of her sexually explicit films, albums and book, and the aggressive appearance on Letterman

Q: Question: "The name the "La Brea Tar Pits" is ironic because it is made up of what?" Context: "Asphalt/bitumen can sometimes be confused with "coal tar", which is a visually similar black, thermoplastic material produced by the destructive distillation of coal. During the early and mid-20th century when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates. The addition of tar to macadam roads led to the word tarmac, which is now used in common parlance to refer to road-making materials. However, since the 1970s, when natural gas succeeded town gas, asphalt/bitumen has completely overtaken the use of coal tar in these applications. Other examples of this confusion include the La Brea Tar Pits and the Canadian oil sands, both of which actually contain natural bitumen rather than tar. Pitch is another term sometimes used at times to refer to asphalt/bitumen, as in Pitch Lake." Answer:
A: natural bitumen rather than tar

Question: Question: "Who ultimately ensured the rights of members of a university?" Context: "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." Answer:
Answer: princes, prelates, or the towns in which they were located

[Q]: Question: "How does Digimon life cycle differ from real organisms?" Context: "The first Digimon anime introduced the Digimon life cycle: They age in a similar fashion to real organisms, but do not die under normal circumstances because they are made of reconfigurable data, which can be seen throughout the show. Any Digimon that receives a fatal wound will dissolve into infinitesimal bits of data. The data then recomposes itself as a Digi-Egg, which will hatch when rubbed gently, and the Digimon goes through its life cycle again. Digimon who are reincarnated in this way will sometimes retain some or all their memories of their previous life. However, if a Digimon's data is completely destroyed, they will die." Answer:
****
[A]: do not die under normal circumstances

Problem: Given the question: Question: "Who fought in the Chechen War?" Context: "The post-Imperial nature of Russian subdivision of government changed towards a generally autonomous model which began with the establishment of the USSR (of which Russia was governed as part). It was liberalized in the aftermath of the Soviet Union, with the reforms under Boris Yeltsin preserving much of the Soviet structure while applying increasingly liberal reforms to the governance of the constituent republics and subjects (while also coming into conflict with Chechen secessionist rebels during the Chechen War). Some of the reforms under Yeltsin were scaled back by Vladimir Putin." Answer:
++++++++++++++++++++++++++++++++
The answer is:
Chechen secessionist rebels
