Example Input: Question: How old was Itagaki Taisuke when he started The Freedom and People's Rights Movement? Passage:A major proponent of representative government was Itagaki Taisuke, a powerful leader of Tosa forces who had resigned from his Council of State position over the Korean affair in 1873. Itagaki sought peaceful rather than rebellious means to gain a voice in government. Such movements were called The Freedom and People's Rights Movement. He started a movement aimed at establishing a constitutional monarchy and a national assembly. Itagaki and others wrote the Tosa Memorial in 1874 criticizing the unbridled power of the oligarchy and calling for the immediate establishment of representative government. Dissatisfied with the pace of reform after having rejoined the Council of State in 1875, Itagaki organized his followers and other democratic proponents into the nationwide Aikokusha (Society of Patriots) to push for representative government in 1878. In 1881, in an action for which he is best known, Itagaki helped found the Jiyūtō (Liberal Party), which favored French political doctrines. In 1882 Ōkuma Shigenobu established the Rikken Kaishintō (Constitutional Progressive Party), which called for a British-style constitutional democracy. In response, government bureaucrats, local government officials, and other conservatives established the Rikken Teiseitō (Imperial Rule Party), a pro-government party, in 1882. Numerous political demonstrations followed, some of them violent, resulting in further government political restrictions. The restrictions hindered the political parties and led to divisiveness within and among them. The Jiyūtō, which had opposed the Kaishintō, was disbanded in 1884, and Ōkuma resigned as Kaishintō president.

At Crandon Bridge the A39 road crosses the Drain to a 'T'-junction with the old course of the A39 to Glastonbury and the newer A39 spur to the M5 motorway. Passing to the south of Puriton, it turns first west and then south-west as it passes under the M5 motorway, the Bristol and Exeter Railway, and the A38 road in quick succession, to reach the River Parrett at Dunball clyse.
