Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Example Input: Passage: The 1995–96 NBA season was the 76ers 47th season in the National Basketball Association, and 33rd season in Philadelphia. During the offseason, the Sixers signed free agent Vernon Maxwell, then later on signed second-year guard Trevor Ruffin in December. Top draft pick Jerry Stackhouse and Clarence Weatherspoon both provided a nice young nucleus from which to build. However, finding talent to surround them was often difficult, as the Sixers suffered an 11-game losing streak after a 2–2 start. Early into the season, Shawn Bradley was traded to the New Jersey Nets for Derrick Coleman, who only played in just eleven games due to an irregular heartbeat. At midseason, second-year forward Sharone Wright was dealt to the expansion Toronto Raptors as Jeff Malone was released to free agency. The Sixers had their worst season since the infamous 73-loss 1972–73 season, finishing last place in the Atlantic Division with an 18–64 record. 
 Link Information: He was selected first overall in the 1990 NBA draft  Answer: 1990 
Example Output: When was the player that Shawn Bradley was traded to the New Jersey for drafted into the NBA?

Example Input: Passage: In August 2012, he made his European debut for the club, coming on as a substitute in a UEFA Europa League qualifying match against Gomel, replacing Joe Cole in a 0–1 away win. The following week, Sterling scored his first goal for the senior team with a first-half strike in a friendly against Bayer Leverkusen. On 23 August 2012, he started his first match for Liverpool in a Europa League qualifying match away to Hearts in a 0–1 win. He was given his first start in the league three days later in a 2–2 draw at Anfield to Manchester City. He played the full 90 minutes in the loss to Arsenal on 2 September, and the draw with Sunderland on 15 September, where he registered one assist and was named man of the match. On 19 September, Sterling was one of the group of teenagers that travelled to Switzerland to play Young Boys in a UEFA Europa League group match. He replaced Stewart Downing in the second half as Liverpool won 3–5. On 20 October, Sterling scored his first senior competitive goal for Liverpool in the 29th minute in a 1–0 league win against Reading with a strike from the edge of the box. As a result, he became the second-youngest player ever to score in a competitive fixture for Liverpool, behind only Michael Owen.

Example Input: Passage: DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934. In 1956 he established Isotopes, Incorporated to provide radioactive isotopes for oilfield and industrial purposes.
