Task: Question Generation
Input (English): Passage: News of the two battles reached England in August. After several months of negotiations, the government of the Duke of Newcastle decided to send an army expedition the following year to dislodge the French. They chose Major General Edward Braddock to lead the expedition. Word of the British military plans leaked to France well before Braddock's departure for North America. In response, King Louis XV dispatched six regiments to New France under the command of Baron Dieskau in 1755. The British sent out their fleet in February 1755, intending to blockade French ports, but the French fleet had already sailed. Admiral Edward Hawke detached a fast squadron to North America in an attempt to intercept them. In a second British action, Admiral Edward Boscawen fired on the French ship Alcide on June 8, 1755, capturing her and two troop ships. The British harassed French shipping throughout 1755, seizing ships and capturing seamen. These actions contributed to the eventual formal declarations of war in spring 1756.
Output (English): How many years did it take to the eventual declarations of war?
