This task involves creating answers to complex questions, from a given passage. Answering these questions, typically involve understanding multiple sentences. Make sure that your answer has the same type as the "answer type" mentioned in input. The provided "answer type" can be of any of the following types: "span", "date", "number". A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words.

Example input: Passage: The outbreak of the Seven Years' War in Europe in 1756 resulted in renewed conflict between French and British forces in India. The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757. However, the war was decided in the south, where the British successfully defended Madras, and Sir Eyre Coote decisively defeated the French, commanded by Comte de Lally at the Battle of Wandiwash in 1760. After Wandiwash, the French capital of Pondicherry fell to the British in 1761. The war concluded with the signing of the Treaty of Paris in 1763, which returned Chandernagore and Pondichery to France, and allowed the French to have "factories" in India but forbade French traders from administering them. The French agreed to support British client governments, thus ending French ambitions of an Indian empire and making the British the dominant foreign power in India.
Question: Which french settlement did the British capture first, Chandernagore or Pondicherry
Answer type: Span
Example output: Chandernagore
Example explanation: British captured Chandernagore in 1757 ("The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757") and Pondicherry in 1761 ("After Wandiwash, the French capital of Pondicherry fell to the British in 1761."). Since 1757<1761, the answer is "Chandernagore".
Q: Passage: The Gelegotis Bridge is a four-lane 7,300-foot -long structure, which began operation in 2003. The new elevated design allows auto traffic to move faster, while vessels pass under a 65-foot clearance and through 90 feet of horizontal clearance between the bridge supports. This bridge is named after Paul Gelegotis, a James Island businessman and politician. Paul Gelegotis is also known as "The Father of EMS", as it was he who created the Emergency Medical System in South Carolina. The "9-1-1" line, and medically equipped ambulances resulted. The South Carolina Department of Transportation opened two lanes to vehicles in November 2003, and opened the remaining two lanes in June 2004. Three construction accidents delayed the opening by six months, two of these were caused by cranes falling onto the structure; the third was a worker falling 30 feet from a crane. The new bridge incorporates vehicle emergency lanes, but no demarcated bicycle lanes or sidewalks. It is the first bridge designed to include the South Carolina Department of Transportation's new seismic design criteria. In total, construction of the bridge cost approximately $41.5 million. The bridge was dedicated June 17, 2004. As a result of increased traffic flow and speed over the new bridge, Charleston is considering spending approximately two million dollars to build a tunnel beneath the bridge approach ramps so golf carts and pedestrians are able to safely cross.
Question: How many accidents were caused by cranes falling onto the structure?
Answer type: Number
A:
2.
