PROBLEM: Question: Of the first two post-doc positions John Ellis held, which company did he work for the longest? Passage:After completing his secondary education at Highgate School, he attended King's College, Cambridge, earning his PhD in theoretical (high-energy) particle physics in 1971. After brief post-doc positions at SLAC and Caltech, he went to CERN and has held an indefinite contract there since 1978. He was awarded the Maxwell Medal and the Paul Dirac Prize by the Institute of Physics in 1982 and 2005 respectively, and is an Elected Fellow of the Royal Society of London since 1985 and of the Institute of Physics since 1991. He was awarded an Honorary Doctorate from the University of Southampton, and twice won the First Award in the Gravity Research Foundation essay competition (in 1999 and 2005). He is also Honorary Doctor at Uppsala University.

PROBLEM: Question: Who was the elder of the two men De La Pole escaped from when he fled to France? Passage:He was appointed Chancellor in 1383, and created Earl of Suffolk in 1385, the first of his family to hold any such title (the earldom had become extinct in 1382 on the death of William de Ufford). However, in the late 1380s his fortunes radically altered, in step with those of the king. During the Wonderful Parliament of 1386 he was impeached on charges of embezzlement and negligence, a victim of increasing tensions between Parliament and Richard. He was the first official in English history to be removed from office by the process of impeachment. Even after this disgrace, he remained in royal favour, although soon fell foul of the Lords Appellant. He was one of a number of Richard's associates accused of treason by the Appellants in November 1387. After the Appellants' victory at Radcot Bridge (December 1387) and before the so-called Merciless Parliament met in February 1388, De La Pole shrewdly fled to Paris, thus escaping the fate of Sir Nicholas Brembre and Chief Justice Robert Tresilian. He remained in France for the remainder of his life. Sentenced in his absence, his title and estates were stripped from him.

PROBLEM: Question: What year range was the mountain formed during? Passage:West Suffield Mountain, like much of the Metacomet Ridge, is composed of basalt, also called traprock, a volcanic rock. The mountain formed near the end of the Triassic Period with the rifting apart of the North American continent from Africa and Eurasia. Lava welled up from the rift and solidified into sheets of strata hundreds of feet thick. Subsequent faulting and earthquake activity tilted the strata, creating the cliffs and ridgeline of West Suffield Mountain. Hot, dry upper slopes, cool, moist ravines, and mineral-rich ledges of basalt talus produce a combination of microclimate ecosystems on the mountain that support plant and animal species uncommon in greater Connecticut. West Suffield Mountain is also an important raptor migration path. (See Metacomet Ridge for more information on the geology and ecosystem of West Suffield Mountain).
