Here is a question about this article: Although the numbered streets begin just north of East Houston Street in the East Village, they generally do not extend west into Greenwich Village, which already had streets when the grid plan was laid out by the Commissioners' Plan of 1811. Streets that do continue farther west change direction before reaching the Hudson River. The grid covers the length of the island from 14th Street north.
What is the answer to this question: Who laid out the Grid Plan?
****
So... Commissioners' Plan of 1811

Here is a question about this article: Development of a solar-powered car has been an engineering goal since the 1980s. The World Solar Challenge is a biannual solar-powered car race, where teams from universities and enterprises compete over 3,021 kilometres (1,877 mi) across central Australia from Darwin to Adelaide. In 1987, when it was founded, the winner's average speed was 67 kilometres per hour (42 mph) and by 2007 the winner's average speed had improved to 90.87 kilometres per hour (56.46 mph). The North American Solar Challenge and the planned South African Solar Challenge are comparable competitions that reflect an international interest in the engineering and development of solar powered vehicles.
What is the answer to this question: What was the average speed of a winning solar powered car by 2007?
****
So... 90.87 kilometres per hour (56.46 mph)

Here is a question about this article: Visual anthropology is concerned, in part, with the study and production of ethnographic photography, film and, since the mid-1990s, new media. While the term is sometimes used interchangeably with ethnographic film, visual anthropology also encompasses the anthropological study of visual representation, including areas such as performance, museums, art, and the production and reception of mass media. Visual representations from all cultures, such as sandpaintings, tattoos, sculptures and reliefs, cave paintings, scrimshaw, jewelry, hieroglyphics, paintings and photographs are included in the focus of visual anthropology.
What is the answer to this question: What are performances, art, and the production of mass media grouped under?

So...
visual representation
