Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Who has played for more teams the original striker for FC Porto at the beginning of 2003-04 season or the player that replaced him? Passage:The 2003–04 season began with another 1–0 win over União de Leiria, which gave the club its 13th Supertaça. Weeks later, Porto failed to repeat this result in the 2003 UEFA Super Cup, losing 1–0 to Milan. The departure of striker Hélder Postiga was compensated by the signing of South Africa's Benni McCarthy, whose 20 league goals helped Porto in its league title defence and crowned him the competition's top scorer. Mourinho entered the 2003–04 UEFA Champions League with confidence to his team. Porto finished second in its group, losing only once to Real Madrid, and advanced to a round-of-16 meeting with Manchester United. Porto scored on the 90th minute of the second leg at Old Trafford to draw 1–1 and advance to the quarter-finals with a 3–2 aggregate win. The team then overcame Lyon and Deportivo La Coruña and reached the Champions League final, where it defeated Monaco 3–0 to lift the club's second European Champion Clubs' Cup. A 2–1 loss to Benfica in the Taça de Portugal final, held 10 days before, prevented another treble-winning season.

Example Input: Question: Who became president of the United States after Coolidge left office? Passage:Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 – January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.
