Background: Matthew Fontaine Maury (January 14, 1806 - February 1, 1873) was an American astronomer, United States Navy officer, historian, oceanographer, meteorologist, cartographer, author, geologist, and educator. He was nicknamed "Pathfinder of the Seas" and "Father of Modern Oceanography and Naval Meteorology" and later, "Scientist of the Seas" for his extensive works in his books, especially The Physical Geography of the Sea (1855), the first such extensive and comprehensive book on oceanography to be published. Maury made many important new contributions to charting winds and ocean currents, including ocean lanes for passing ships at sea.
Context: Maury was a descendant of the Maury family, a prominent Virginia family of Huguenot ancestry that can be traced back to 15th-century France. His grandfather (the Reverend James Maury) was an inspiring teacher to a future US president, Thomas Jefferson. Maury also had Dutch-American ancestry from the "Minor" family of early Virginia.  He was born in 1806 in Spotsylvania County, Virginia, near Fredericksburg; his parents were Richard Maury and Diane Minor Maury. The family moved to Franklin, Tennessee, when he was five. He wanted to emulate the naval career of his older brother, Flag Lieutenant John Minor Maury, who, however, caught yellow fever after fighting pirates as an officer in the US Navy. As a result of John's painful death, Matthew's father, Richard, forbade him from joining the Navy. Maury strongly considered attending West Point to get a better education than the Navy could offer at that time, but instead, he obtained a naval appointment through the influence of Tennessee Representative Sam Houston, a family friend, in 1825, at the age of 19.  Maury joined the Navy as a midshipman on board the frigate Brandywine which was carrying the Marquis de La Fayette home to France, following La Fayette's famous visit to the United States. Almost immediately, Maury began to study the seas and to record methods of navigation. One of the experiences that piqued this interest was a circumnavigation of the globe on the USS Vincennes, his assigned ship and the first US warship to travel around the world.
Question: When was he appointed?
Answer: in 1825, at the age of 19.

Problem: Background: Samuel Luther "Big Sam" Thompson (March 5, 1860 - November 7, 1922) was an American professional baseball player from 1884 to 1898 and with a brief comeback in 1906. At 6 feet, 2 inches, the Indiana native was one of the larger players of his day and was known for his prominent handlebar mustache. He played as a right fielder in Major League Baseball for the Detroit Wolverines (1885-88), Philadelphia Phillies (1889-1898) and Detroit Tigers (1906). He was inducted into the Baseball Hall of Fame in 1974.
Context: In 15 major league seasons, Thompson compiled a .331 batting average with 1,988 hits, 343 doubles, 161 triples, 126 home runs, 1,305 RBIs, and 232 stolen bases. He was inducted into the Baseball Hall of Fame in 1974.  Thompson was one of the most prolific run producers in baseball history. His career RBI to games played ratio of .923 (1,305 RBIs in 1,410 games) remains the highest in major league history, higher even than Lou Gehrig (.921), Hank Greenberg (.915), Joe DiMaggio (.885), and Babe Ruth (.884). In 1895, Thompson averaged 1.44 RBIs per game (147 RBIs in 102 games), still a major league record. His 166 RBIs in 1887 (in only 127 games) was 62 more than anyone else in the league that year, and it stood as the major league record until 1921 when Babe Ruth collected 168 (albeit in 152 games). Thompson still holds the major league record for most RBIs in a single month with 61 in August 1894 while playing for the Phillies.  Thompson was also one of the best power hitters of the era before Babe Ruth. At the end of the 19th century, Thompson's 126 career home runs ranked second only to Roger Connor. Defensively, Thompson still ranks among the all-time major league leaders with 61 double plays from the outfield (16th all time) and 283 outfield assists (12th all time). Thompson has also been credited by baseball historians with perfecting "the art of throwing the ball to the plate on one bounce, which catchers found easier to handle than the usual throw on the fly." Bill Watkins, who managed Thompson in Detroit, recalled: "He was a fine fielder and had a cannon arm and will live in my memory as the greatest natural hitter of all time."  In a 1913 story on Thompson, Detroit sports writer Maclean Kennedy noted that Thompson's drives "were the direct cause of more hats being smashed, more backs that were thumped til they were black and blue by some wild-eyed fan sitting in the seat behind, more outbursts of frenzied shrieks and howls of glee, than those of any other player who ever wore a Detroit uniform", barring only the two great stars of the day, Ty Cobb and Sam Crawford.
