Question: Passage: Henry Scott Riddell was born on 23 September 1798 in Sorbie, near Langholm, Dumfriesshire, the third child of seven to Robert Riddell, a shepherd, and his wife Agnes (née Scott). His father was reportedly an associate of the Scottish poets James Hogg, the Ettrick Shepherd, who would occasionally visit their household and recite his own poetry to the children, and Walter Scott, as well as Sir Pulteney Malcolm. His elder brother, Borthwick Riddell, known as The Piper, was a locally renowned player of the bagpipes who notably played at the wedding of John Russell, 1st Earl Russell to Lady Frances Anna-Maria Elliot-Murray-Kynynmound, daughter of Gilbert Elliot, 2nd Earl of Minto, on 20 July 1841. His younger brother, Robert Riddell, emigrated to Canada and was an early pioneer of Beverley Township in Ontario. He also participated in the Upper Canada Rebellion, coming to be known as The Chief, leading dozens of men from County Wentworth in a march to Woodstock, Ontario.

Question: Passage: Kepler-8b has a mass of .603 M, but a radius of 1.419 R. This means that although Kepler is approximately 60% the mass of planet Jupiter, it is more diffuse, as it is 41.9% wider. Based on its size and the distance from its star, Kepler-8b is a Hot Jupiter planet, orbiting Kepler-8 from a distance of .0483 AU every 3.52254 days. To compare, planet Mercury orbits the Sun at an average distance of .3871 AU every 87.97 days. With an equilibrium temperature of 1764 K, Kepler-8b was the hottest of the five planets announced during the conference stating its discovery. Kepler-8b has an eccentricity of 0, which means that its orbit is very circular. The planet also has a density of .261 grams/cc, approximately 74% less dense than purified water at 4 °C.

Answer: What is the diameter of the planet that orbits the Sun at an average distance of .3871 AU every 87.97 days


Question: Passage: Brown was born in 1937 in Lewes, Sussex, one of six brothers who all played football; two, Irvin and Stan, also played in the Football League. He played local football for Lewes St Mary's and Portslade before being called up for National Service. A tall, heavily built man, Brown was serving in Gibraltar in March 1958 when he was recommended to Brighton & Hove Albion as a promising centre half; he signed for the club six months later, the day after his brother Irvin, also a centre half, left it. He made his first-team debut three years later, by which time he had converted to play at centre forward, and made eight appearances, scoring twice, in the first half of the 1961–62 Second Division season. In January 1962, he joined Exeter City, managed by former Brighton team-mate Glen Wilson. He scored three goals from eleven Division Four appearances, and left at the end of the season for non-league football with clubs including Hastings United and Dover. After football, Brown worked as a landscape gardener. He died in Lewes in 2016 at the age of 78.
