Q: Question: How old were Norman Tindale and Joseph Birdsell when they published their paper about the 12 Negrito tribes? Passage 1:In later years, Continental Express continued to serve the airport with nonstop regional jet flights to Cleveland while Continental Connection was operating nonstop turboprop flights to Albany, NY; however, both services ended in 2005. Spirit Airlines scheduled flights to several Florida cities and Detroit, before moving to LaGuardia Airport in 2001; in May 2008 the airline resumed service to Fort Lauderdale from MacArthur only to drop it soon after. Delta Express, which had nonstops to Orlando and Fort Lauderdale, dropped MacArthur Airport in 2003 after a decline in traffic. Delta Connection regional jet service to Atlanta flown by Atlantic Southeast Airlines (ASA) on behalf of Delta Air Lines ended on May 1, 2008 following a mid-April announcement that Delta and Northwest Airlines were planning to merge – a move that led to changes for the merged airline.
 Passage 2:In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.
 Passage 3:Friedman graduated from the University of Houston with a degree in philosophy in 1956. During his career, he wrote for the Houston Chronicle, the Detroit Free Press, Newsday, and for Knight Ridder newspapers. He won a 1963 Nieman Fellowship. His work landed him on the master list of Nixon political opponents. He was one member of a team that covered the 1967 Detroit riot for the Detroit Free Press. Next year they shared the Pulitzer Prize in Local General or Spot News Reporting (a predecessor of the Breaking News Pulitzer), citing "both the brilliance of its detailed spot news staff work and its swift and accurate investigation into the underlying causes of the tragedy." Friedman also taught national and foreign affairs reporting at the Columbia University Graduate School of Journalism for a year. In 1985, Friedman and his family moved to Edgewater, Maryland, where Friedman worked as a White House correspondent. Friedman began working for Newsday, although he left to spend five months in South Africa teaching journalists. After his return, Friedman wrote a weekly column called "Gray Matters" that covered issues affecting older people. After working there for more than twenty years, he quit Newsday in October 2009 over its decision to charge for its web content. He began publishing his column in November 2009 in Time Goes By, a blog.
