Context_10 : The 1974 NASCAR Winston Cup Series was the 26th season of professional stock car racing in the United States and the 3rd modern era NASCAR Cup series. The season began on Sunday January 20 and ended on Sunday November 24. The first 15 races were shortened 10 percent due to the 1973 oil crisis. Following criticism of the 1972 and 1973 points systems that placed emphasis on completed miles, NASCAR implemented a new points system, that took basic purse winnings, multiplied by number of starts, and divided by 1,000; it was designed to more directly reward winning races, a response to Benny Parsons' championship the previous year with just one win. Richard Petty was Winston Cup champion at the end of the season finishing 567.45 points ahead of Cale Yarborough, while David Pearson finished a strong third in points despite only nineteen starts. Earl Ross was named NASCAR Rookie of the Year. fact_1 :  With his colleague Jock Colville, he was one of Churchill's last two principal private secretaries at 10 Downing Street. fact_2 : 10 Downing Street, colloquially known in the United Kingdom as Number 10, is the headquarters of the Government of the United Kingdom and the official residence and office of the First Lord of the Treasury, a post which, for much of the 18th and 19th centuries and invariably since 1905, has been held by the Prime Minister.
