In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: Which country's emperor had Gramont imprisoned due to his role in founding the League of Cognac? Passage 1:On August 2, 2008, a trough entered the northern Gulf of Mexico, with a low pressure area developing near Apalachicola, Florida. The system maintained scattered deep convection across offshore waters and environmental conditions favored tropical cyclogenesis. The system tracked generally west-southwestward, due to its position south of a subtropical ridge extending from Texas through Florida. On the afternoon of August 3, a Hurricane Hunters flight into the system confirmed the development of a well-defined center of circulation, slightly exposed from a disorganized area of thunderstorms. As a result, the system developed into Tropical Depression Five at 1200 UTC on August 3, while located about 85 miles (140 km) south of the mouth of the Mississippi River. Because the depression was initially located in an area of northerly wind shear and dry air, the National Hurricane Center forecast it to slowly intensify.
 Passage 2:He was maître des suppliques under Francis I of France. He was promoted to the metropolitan see of Bordeaux. In 1525, the queen regent, Louise of Savoy sent Bishop Gramont to Spain to secure the freedom of Francis I. In 1526, he was imprisoned by Charles V, Holy Roman Emperor, who was angry at his role in founding the League of Cognac; when England and France arrested the imperial ambassadors, the emperor ordered Bishop Gramont released. Returning to the Kingdom of France, he was despatched to the Kingdom of England in an attempt to encourage Henry VIII of England to divorce Catherine of Aragon and form a French alliance by marrying Marguerite de Navarre, the widow of the king's brother Charles IV, Duke of Alençon. He was then sent as French ambassador to the Holy See.
 Passage 3:The Bristol Channel has some extensive and popular beaches and spectacular scenery, particularly on the coasts of Exmoor and Bideford Bay in North Devon and the Vale of Glamorgan and Gower Peninsula on the Glamorgan coast. The western stretch of Exmoor boasts Hangman cliffs, the highest cliffs in mainland Britain, culminating near Combe Martin in the "Great Hangman", a 1,043 ft (318 m) 'hog-backed' hill with a cliff-face of 820 ft (250 m); its sister cliff the "Little Hangman" has a cliff-face of 716 ft (218 m). On the Gower Peninsula, at its western extremity is the Worms Head, a headland of carboniferous limestone which is approachable on foot at low tide only. The beaches of Gower (at Rhossili, for example) and North Devon, such as Croyde and Woolacombe, win awards for their water quality and setting, as well as being renowned for surfing. In 2004, The Times "Travel" magazine selected Barafundle Bay in Pembrokeshire as one of the twelve best beaches in the world. In 2007, Oxwich Bay made the same magazine's Top 12 best beaches in the world list, and was also selected as Britain's best beach for 2007.
