Input: Read this: In the subtractive color system, used in painting and color printing, green is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. On the HSV color wheel, also known as the RGB color wheel, the complement of green is magenta; that is, a color corresponding to an equal mixture of red and blue light (one of the purples). On a traditional color wheel, based on subtractive color, the complementary color to green is considered to be red.
Question: What is the complementary color to blue?

Output: unanswerable

Input: Read this: The Zipingpu Hydropower Plant (simplified Chinese: ; traditional Chinese: ) located 20 km east of the epicenter was damaged. A recent inspection indicated that the damage was less severe than initially feared, and it remains structurally stable and safe. The Tulong reservoir upstream is in danger of collapse. About 2,000 troops have been allocated to Zipingpu, trying to release the pressure through spillway. In total, 391 dams, most of them small, were reported damaged by the quake.
Question: What power plant was damaged by the earthquake?

Output: Zipingpu Hydropower Plant

Input: Read this: These decisions, apparently taken at the Luftflotte or Fliegerkorps level (see Organisation of the Luftwaffe (19331945)), meant attacks on individual targets were gradually replaced by what was, for all intents and purposes, an unrestricted area attack or Terrorangriff (Terror Attack). Part of the reason for this was inaccuracy of navigation. The effectiveness of British countermeasures against Knickebein, which was designed to avoid area attacks, forced the Luftwaffe to resort to these methods. The shift from precision bombing to area attack is indicated in the tactical methods and weapons dropped. KGr 100 increased its use of incendiaries from 1328 percent. By December, this had increased to 92 percent. Use of incendiaries, which were inherently inaccurate, indicated much less care was taken to avoid civilian property close to industrial sites. Other units ceased using parachute flares and opted for explosive target markers. Captured German air crews also indicated the homes of industrial workers were deliberately targeted.
Question: What was one of the reasons for unrestricted area attacks?

Output: inaccuracy of navigation

Input: Read this: Early human genetic cluster analysis studies were conducted with samples taken from ancestral population groups living at extreme geographic distances from each other. It was thought that such large geographic distances would maximize the genetic variation between the groups sampled in the analysis and thus maximize the probability of finding cluster patterns unique to each group. In light of the historically recent acceleration of human migration (and correspondingly, human gene flow) on a global scale, further studies were conducted to judge the degree to which genetic cluster analysis can pattern ancestrally identified groups as well as geographically separated groups. One such study looked at a large multiethnic population in the United States, and "detected only modest genetic differentiation between different current geographic locales within each race/ethnicity group. Thus, ancient geographic ancestry, which is highly correlated with self-identified race/ethnicityas opposed to current residenceis the major determinant of genetic structure in the U.S. population." (Tang et al. (2005))
Question: Where did the groups the genetic clusters were taken from live from each other?

Output:
extreme geographic distances
