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.

Example Input: Question: What is the location of the headquarters for the company that makes 3M tape? Passage:Surgical tape or medical tape is a type of pressure-sensitive adhesive tape used in medicine and first aid to hold a bandage or other dressing onto a wound. These tapes usually have a hypoallergenic adhesive which is designed to hold firmly onto skin, dressing materials, and underlying layers of tape, but to remove easily without damaging the skin. They allow air to reach the skin ("breathable"). Some breathable tapes such as Kinesiology Tape, and other elastic bandages with adhesive are made of cotton. Surgical tape is often white because it contains zinc oxide, which is added to help prevent infections. Tapes made of microporous material, such as 3M Micropore, are widely used.

Example Input: Question: What city was Jet Ski Lady's last race in? Passage:Jet Ski Lady (foaled 20 February 1988) was an American-bred, Irish-trained thoroughbred racehorse, best known for winning The Oaks in 1991. In a racing career which lasted from June 1990 to October 1991 the filly ran ten times and won four races. After winning twice as a two-year-old, Jet Ski Lady competed against colts with mixed success in early 1991 before winning the Classic Oaks over one and a half miles at Epsom Downs Racecourse. Her winning margin of ten lengths was the second-widest in the race's history and her starting price of 50/1 made her the equal longest-priced winner of the Oaks on records. She subsequently finished second in both the Irish Oaks at the Curragh and the Yorkshire Oaks at York. She was retired to stud after finishing unplaced in the Prix de l'Arc de Triomphe.

Example Input: Question: How long was the reign of Minbya's grandfather? Passage:Thado Minbya was born Rahula to Princess Soe Min Kodawgyi of Sagaing and Viceroy Thado Hsinhtein of Tagaung in 1345. From his mother's side, he was a grandson of King Saw Yun, the founder of the Sagaing Kingdom, and nephew of then reigning king Kyaswa as well as a great grandson of King Thihathu of Pinya and King Kyawswa of Pagan. From his father's side, he was descended from a line of hereditary rulers of Tagaung from the House of Thado. According to British colonial period scholarship, his father was an ethnic Shan and his mother was mostly Shan; however some have argued that no extant chronicle or archaeological evidence supports the conjecture. The prince had two younger sisters: Shin Saw Gyi and Saw Omma. His father died soon after the birth of Saw Omma. His mother remarried to Thihapate, a grandnephew of Queen Pwa Saw of Pagan. In 1352, Thihapate became king of Sagaing.
