After an hour's drive through mere countryside, in bright sunshine, they entered Trumpington Street in Cambridge soon after midday.(汽車又在鄉間行駛了一個小時，正午剛過，他們在燦爛的陽光下便駛進劍橋的特倫平頓大街。)

John Coates, once a trader on Wall Street and now a neuroscientist at Cambridge University, presents yet another culprit: biology, or, more precisely, the physiology of risk-taking.(約翰·科茨曾是華爾街的交易員，如今身為劍橋大學神經科學家的他，認為另有生物學因素在作祟，確切來說是冒險生理機能。)

He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump.(他還發現，這些人都在劍橋街7號的酒館里打工，而酒館為他們提供免費的啤酒喝，因此他們沒有喝從寬街水泵抽上來的水。)
