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.

Problem: 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
Solution: Chandernagore
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".

Problem: Passage: With the death of Admiral Stepan Makarov during the siege of Port Arthur in April 1904, Admiral Wilgelm Vitgeft was appointed commander of the battle fleet and was ordered to make a sortie from Port Arthur and deploy his force to Vladivostok. Flying his flag in the French-built pre-dreadnought Tsesarevich, Vitgeft proceeded to lead his six battleships, four cruisers, and 14 torpedo boat destroyers into the Yellow Sea in the early morning of 10 August 1904. Waiting for him was Admiral Togo and his fleet of four battleships, 10 cruisers, and 18 torpedo boat destroyers. At approximately 12:15, the battleship fleets obtained visual contact with each other, and at 13:00 with Togo crossing Vitgeft's T, they commenced main battery fire at a range of about eight miles, the longest ever conducted up to that time. For about thirty minutes the battleships pounded one another until they had closed to less than four miles and began to bring their secondary batteries into play. At 18:30, a hit from one of Togo's battleships struck Vitgeft's flagship's bridge, killing him instantly. With the Tsesarevich's helm jammed and their admiral killed in action, she turned from her battle line, causing confusion among her fleet. However, Togo was determined to sink the Russian flagship and continued pounding her, and it was saved only by the gallant charge of the American-built Russian battleship Retvizan, whose captain successfully drew away Togo's heavy fire from the Russian flagship. Knowing of the impending battle with the battleship reinforcements arriving from Russia , Togo chose not to risk his battleships by pursuing his enemy as they turned about and headed back into Port Arthur, thus ending naval history's longest-range gunnery duel up to that time and the first modern clash of steel battleship fleets on the high seas.
Question: How many minutes after the time the battleship fleets obtained visual contact with each other did a torpedo strike Vitgefts flagship's bridge, killing him?
Answer type: Number
Solution:
315.
