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: In what state did Lisa Lisa appear at the eighth annual Forever Freestyle showcase? Passage:Lisa Lisa released a solo album called LL77 in 1994, which included the moderate club hit "When I Fell In Love" (which was remixed by Junior Vasquez) and the notable single "Skip to My Lu", which hit No. 38 on the R&B chart. She resurfaced circa 2001 on the Nickelodeon series Taina, in which she played the title character's mother. On June 24, 2008, Lisa Lisa presented an award at the BET Awards sparking interest that she may be plotting a comeback. In 2009, she released Life 'n Love, a full-length album of new material on Mass Appeal Entertainment featuring the single "Can't Wait" with guest rapper Pitbull. The album also features a cover version of the song "Stand" which was originally performed by Taylor Dayne on her 1998 album Naked without You.

Input: Consider Input: Question: How high is the gamma radiation from nuclear fuel? Passage:The nuclear fuel elements were made of refractory ceramic based on beryllium oxide, with enriched uranium dioxide as fuel and small amount of zirconium dioxide for structural stability. The fuel elements were hollow hexagonal tubes about long with distance between the outer parallel planes, with inside diameter of . They were manufactured by high-pressure extruding of the green compact, then sintering almost to its theoretical density. The core consisted of 465,000 individual elements stacked to form 27,000 airflow channels; the design with small unattached elements reduced problems related with thermal stresses. The elements were designed for average operation temperature of ; the autoignition temperature of the reactor base plates was only 150 °C higher. The neutron flux was calculated to be 9×10 neutrons/(cm·s) in the aft and 7×10 neutrons/(cm·s) in the nose. The gamma radiation level was fairly high due to the lack of shielding; radiation hardening for the guidance electronics had to be designed.

Input: Consider Input: Question: Which team won the NHL title the season that Thomas began his career? Passage:Thomas went undrafted after his junior career but signed as a Free Agent with the Toronto Maple Leafs. He began his NHL career in the 1984–85 season. Thomas was born in Stockport, England but was raised in Markham, Ontario, Canada where he attended Markham District High School. As he often coasted in school on his hockey skills, he once had a teacher tell him to "smarten up, Steve; hockey can only take you so far". He played junior hockey for the Toronto Marlboros of the OHL (he was the last original Toronto Marlboro to make it to the Maple Leafs of the NHL). Prior to playing in the NHL, Thomas won the Dudley "Red" Garrett Memorial Award in 1985 as the top rookie in the American Hockey League, while playing for the St. Catharines Saints.
