In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Input: Consider 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 Jiyuto (Liberal Party), which favored French political doctrines. In 1882 Okuma Shigenobu established the Rikken Kaishinto (Constitutional Progressive Party), which called for a British-style constitutional democracy. In response, government bureaucrats, local government officials, and other conservatives established the Rikken Teiseito (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 Jiyuto, which had opposed the Kaishinto, was disbanded in 1884, and Okuma resigned as Kaishinto president.

Input: Consider Input: Question: How many times did the man Mari George rode in the pace car with in 2011 win the Indianapolis 500? Passage:In most cases, Tony Hulman would give the command, then ride in the pace car during the pace laps. Mary F. Hulman would give the command near the pace car, but rarely rode in the pace car due to her age and declining health. Eventually, the location was moved to near the start/finish line, and in 2001, it was moved to the new Victory Podium stage adjacent to the Pagoda. In 2011 only, Mari George moved back to the front of the starting grid to give the command, and then she rode in the pace car with A. J. Foyt. In 2014, as a special gesture to Jim Nabors's final performance at Indy, the starting command was given in unison by both Mari George and Nabors, marking the first time a non-member of the Hulman-George family had given the command for the 500 since 1954. In 2016 for the 100th Indianapolis 500, now-matriarch Mari was joined by three subsequent generations of the Hulman-George family, who gave the command together. Due to her advanced age, the 2016 race would be Mari's final turn giving the command. Later that same year, Tony George gave the starting command for the Brickyard 400, his first time giving a command since a restart command in 1986. For the 2017 Indianapolis 500, the duty was permanently assigned to Tony George. In that year, Tony George began using the phrase "Drivers, start your engines" instead of the more familiar "Lady and gentlemen..." variation. However, for the 2019 race, George recited that latter variation.
