The station was expected to be completed by 2012, but experienced several delays and was later expected to be completed in late 2014, again pushed back to early 2015. Question: In what year was the Miami Central Station originally supposed to have been completed?

Example Input: Passage: Meanwhile, Kerry's staff began their own investigations and, on October 14, issued a report that exposed illegal activities on the part of Lieutenant Colonel Oliver North, who had set up a private network involving the National Security Council and the CIA to deliver military equipment to right-wing Nicaraguan rebels (Contras). In effect, North and certain members of the President's administration were accused by Kerry's report of illegally funding and supplying armed militants without the authorization of Congress. Kerry's staff investigation, based on a year-long inquiry and interviews with fifty unnamed sources, is said to raise "serious questions about whether the United States has abided by the law in its handling of the contras over the past three years." Question: Who had Oliver North been supporting?
Example Output: right-wing Nicaraguan rebels (Contras)

Example Input: Passage: Mary resided in "her own house"[Lk.1:56] in Nazareth in Galilee, possibly with her parents, and during her betrothal — the first stage of a Jewish marriage — the angel Gabriel announced to her that she was to be the mother of the promised Messiah by conceiving him through the Holy Spirit, and she responded, "I am the handmaid of the Lord. Let it be done unto me according to your word." After a number of months, when Joseph was told of her conception in a dream by "an angel of the Lord", he planned to divorce her; but the angel told him to not hesitate to take her as his wife, which Joseph did, thereby formally completing the wedding rites.[Mt 1:18-25] Question: In his dream, who told Joseph about Mary's conception?
Example Output:
an angel of the Lord
