Input: Article: As of the census of 2000, there were 197,790 people, 84,549 households, and 43,627 families residing in the city. The population density was 3,292.6 people per square mile (1,271.3/km). There were 92,282 housing units at an average density of 1,536.2 per square mile (593.1/km). The racial makeup of the city was 38.3% White, 57.2% African American, 0.2% Native American, 1.3% Asian, 0.1% Pacific Islander, 1.5% from other races, and 1.5% from two or more races. Hispanic or Latino of any race were 2.6% of the population.

Now answer this question: What was the largest racial group in Richmond as of 2000?

Output: African American

Input: Article: Inside ornament was far more generous, and could sometimes be overwhelming. The chimneypiece continued to be the usual main focus of rooms, and was now given a classical treatment, and increasingly topped by a painting or a mirror. Plasterwork ceilings, carved wood, and bold schemes of wallpaint formed a backdrop to increasingly rich collections of furniture, paintings, porcelain, mirrors, and objets d'art of all kinds. Wood-panelling, very common since about 1500, fell from favour around the mid-century, and wallpaper included very expensive imports from China.

Now answer this question: What was the typical main focus of rooms?

Output: chimneypiece

Input: Article: The onset of infrared is defined (according to different standards) at various values typically between 700 nm and 800 nm, but the boundary between visible and infrared light is not precisely defined. The human eye is markedly less sensitive to light above 700 nm wavelength, so longer wavelengths make insignificant contributions to scenes illuminated by common light sources. However, particularly intense near-IR light (e.g., from IR lasers, IR LED sources, or from bright daylight with the visible light removed by colored gels) can be detected up to approximately 780 nm, and will be perceived as red light. Sources providing wavelengths as long as 1050 nm can be seen as a dull red glow in intense sources, causing some difficulty in near-IR illumination of scenes in the dark (usually this practical problem is solved by indirect illumination). Leaves are particularly bright in the near IR, and if all visible light leaks from around an IR-filter are blocked, and the eye is given a moment to adjust to the extremely dim image coming through a visually opaque IR-passing photographic filter, it is possible to see the Wood effect that consists of IR-glowing foliage.

Now answer this question: Up to what wavelength does the human eye perceive certain intense lights as being dull red in color?

Output:
1050 nm
