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: Which artist won the Grammy for Best Contemporary R&B Album the year Omarion was nominated for that award? Passage:In early 2004, Omarion appeared in several films, most notably You Got Served in which he starred alongside Marques Houston, as well as his former B2K bandmates.

That same year, he played the role of the school bully "Reggie" in the comedy Fat Albert, based on the animated series Fat Albert and the Cosby Kids. On February 22, 2005, Omarion released his debut solo album O. The album debuted at #1 on the Billboard 200 and Top R&B/Hip-Hop Albums charts. The first single from the album was "O". The single peaked at #27 on the Billboard Hot 100 chart. The second single "Touch", peaked at #94 on the Billboard Hot 100. The album received a third and final release with, "I'm Tryna". O has sold over 758,000 copies in the United States since its release. Omarion received a Grammy nomination for the album at the 48th Grammy Awards for Best Contemporary R&B Album. On December 26, 2006 Omarion released his second album 21. The album debuted at #1 on the Billboard 200 and Top R&B/Hip-Hop Albums charts. The first single from the album was "Entourage". The second single "Ice Box", produced by Timbaland, peaked at #12 on the Billboard Hot 100 and is Omarion's most successful solo single to date, reaching gold certification by the RIAA. 21 has sold over 390,000 copies in the United States since its release.

Example Input: Question: What countries signed the treaty that acknowledges Ireland's "traditional policy of military neutrality"? Passage:Ireland has been neutral in international relations since the 1930s. The nature of Irish neutrality has varied over time, and has been contested since the 1970s. Historically, the state was a "non-belligerent" in the Second World War (see Irish neutrality during World War II) and has never joined NATO, although during the Cold War it was anti-communist and aloof from the Non-Aligned Movement. The compatibility of neutrality with Ireland's membership of the European Union has been a point of debate in EU treaty referendum campaigns since the 1990s. The Seville Declarations on the Treaty of Nice acknowledge Ireland's "traditional policy of military neutrality", reflecting the narrow formulation of successive Irish governments. Others define Irish neutrality more broadly, as having "a strong normative focus, with a commitment to development, United Nations peacekeeping, human rights and disarmament".
