Here is a question about this article: The Manchester Small-Scale Experimental Machine, nicknamed Baby, was the world's first stored-program computer. It was built at the Victoria University of Manchester by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948. It was designed as a testbed for the Williams tube the first random-access digital storage device. Although the computer was considered "small and primitive" by the standards of its time, it was the first working machine to contain all of the elements essential to a modern electronic computer. As soon as the SSEM had demonstrated the feasibility of its design, a project was initiated at the university to develop it into a more usable computer, the Manchester Mark 1.
What is the answer to this question: Who built the Manchester Small-Scale Experimental Machine?

So... Frederic C. Williams, Tom Kilburn and Geoff Tootill

Here is a question about this article: Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
What is the answer to this question: In the APEX system, the increment that doubles the exposure is called what?

So... "stop"

Here is a question about this article: The evidence of the early texts suggests that Siddhartha Gautama was born in a community that was on the periphery, both geographically and culturally, of the northeastern Indian subcontinent in the fifth century BCE. It was either a small republic, in which case his father was an elected chieftain, or an oligarchy, in which case his father was an oligarch.
What is the answer to this question: When did Siddhartha Gautama live?

So...
fifth century BCE
