Problem: Background: Philip Alfred Mickelson (born June 16, 1970), nicknamed Lefty, is an American professional golfer. He has won 43 events on the PGA Tour, including five major championships: three Masters titles (2004, 2006, 2010), a PGA Championship (2005), and an Open Championship (2013). Mickelson is one of 16 players in the history of golf to win at least three of the four majors. He has won every major except the U.S. Open, where he has finished runner-up a record six times.
Context: Mickelson's first major championship win came in his thirteenth year on the PGA Tour in 2004, when he secured victory in the Masters with an 18-foot (5.5 m) birdie putt on the final hole. Ernie Els was the runner-up at a stroke back; the two played in different pairs in the final round and had traded birdies and eagles on the back nine. In addition to getting the "majors monkey" off his back, Mickelson was now only the third golfer with a left-handed swing to win a major, the others being New Zealander Sir Bob Charles, who won The Open Championship in 1963, and Canadian Mike Weir, who won The Masters in 2003. (Like Mickelson, Weir is a right-hander who plays left-handed.) A fourth left-handed winner is natural southpaw Bubba Watson, the Masters champion in 2012 and 2014. Just prior to the Ryder Cup in 2004, Mickelson was dropped from his long-standing contract with Titleist/Acushnet Golf, when he took heat for a voicemail message he left for a Callaway Golf executive. In it he praised their driver and golf ball, and thanked them for their help in getting some equipment for his brother. This memo was played to all of their salesmen, and eventually found its way back to Titleist. He was then let out of his multi-year deal with Titleist 16 months early, and signed on with Callaway Golf, his current equipment sponsor. He endured a great deal of ridicule and scrutiny from the press and fellow Ryder Cup members for his equipment change so close to the Ryder Cup matches. He faltered at the 2004 Ryder Cup with a 1-3-0 record, but refused to blame the sudden change in equipment or his practice methods for his performance. In November 2004, Mickelson tallied his career-low for an 18-hole round: a 59 at the PGA Grand Slam of Golf at Poipu Bay Golf Course in Hawaii. The following year, Mickelson captured his second major at the PGA Championship at Baltusrol, in a Monday final-round conclusion that had been forced by inclement weather the previous day. On the 18th hole, Mickelson hit one of his trademark soft pitches from deep greenside rough to within a 18 inches (460 mm) of the cup, and made his birdie to finish at a 4-under-par total of 276, one shot ahead of Steve Elkington and Thomas Bjorn. Mickelson captured his third major title the following spring at the Masters. He won his second green jacket after shooting a 3-under-par final round, winning by two strokes over runner-up Tim Clark. This win propelled him to 2nd place in the Official World Golf Ranking (his career best), behind Woods, and ahead of Vijay Singh and Retief Goosen.
Question: What was his 3rd major win?
Answer: third major title the following spring at the Masters.

Problem: Background: Cronin was born in Cardross, Dunbartonshire, Scotland, the only child of a Protestant mother, Jessie Cronin (nee Montgomerie), and a Catholic father, Patrick Cronin. Cronin often wrote of young men from similarly mixed backgrounds. His paternal grandparents had emigrated from County Armagh, Ireland, and become glass and china merchants in Alexandria. Owen Cronin, his grandfather, had had his surname changed from Cronague in 1870.
Context: In 1930 Cronin was diagnosed with a chronic duodenal ulcer and was told that he must take six months' complete rest in the country on a milk diet. At Dalchenna Farm by Loch Fyne he was finally able to indulge his lifelong desire to write a novel, having previously "written nothing but prescriptions and scientific papers". From Dalchenna Farm he travelled to Dumbarton to research the background of his first novel, using the files of Dumbarton Library, which still has the letter from Cronin requesting advice. He composed Hatter's Castle in the span of three months, and the manuscript was quickly accepted by Gollancz, the only publishing house to which it had been submitted (it was apparently chosen when his wife randomly stuck a pin into a list of publishers). This novel, which was an immediate and sensational success, launched Cronin's career as a prolific author, and he never returned to practising medicine. Many of Cronin's books were bestsellers in their day and have been translated into many languages. Some of his stories draw on his medical career, dramatically mixing realism, romance and social criticism. Cronin's works examine moral conflicts between the individual and society, as his idealistic heroes pursue justice for the common man. One of his early novels, The Stars Look Down (1935), chronicles transgressions in a mining community in Northeast England and an ambitious miner's rise to be a Member of Parliament. A prodigiously fast writer, Cronin liked to average 5,000 words a day, meticulously planning the details of his plots in advance. He was known to be tough in business dealings, although in private life he was a person whose "pawky humour ... peppered his conversations," according to one of his editors, Peter Haining. Cronin also contributed many stories and essays to various international publications. During the Second World War he worked for the British Ministry of Information, writing articles as well as participating in radio broadcasts to foreign countries.
Question: when did he start his writing career?
Answer:
In 1930
