Part 2. Example
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
Answer: 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".
Part 3. Exercise
Passage: The city of Taunton has a wide array of architecture ranging from the colonial period to modern times. There are numerous pre-Revolutionary War private homes within the city, the oldest of which is the Joseph Willis House on Worcester Street, dating to about 1688. The city has over one hundred buildings listed on the National Register of Historic Places. Perhaps the most impressive structure in the city is the towering Bristol County Superior Courthouse, built in 1894 and designed by Frank Irving Cooper. With its tall copper dome, the Superior Courthouse is visible from many surrounding areas. It was added to the National Register of Historic Places in 1978. Currently, the Courthouse Complex is undergoing a major expansion and renovation program. Other significant buildings in the city include some fine stone churches, including the First Parish Church , the Pilgrim Congregational Church and St. Mary's Church on Broadway. Downtown Taunton has a number of historic commercial blocks along Main Street, Taunton Green and Broadway, built during the period from about 1840 to 1920. Many large homes built by the wealthy industrialists and merchants of the late 19th and early 20th century line Route 44 both east and west of the city center, while a majority of the city is occupied by more modest wood-framed single and multi-family homes, many over 100 years old. Modern single-family subdivisions, mostly built since the 1950s, exist in the outskirts of the sprawling city. The Central Fire Station at 50 School Street is recognized as the oldest functioning station house in the United States. The historic Taunton City Hall is located adjacent to Church Green.
