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.

[Q]: Question: How long is the fault that lies to the east of Ice Mountain? Passage:Ice Mountain is an arc-shaped forested ridge of the Allegheny Mountains, part of the Ridge-and-valley Appalachians. It is above mean sea level at its summit. Ice Mountain is a large mass of Devonian Oriskany (Ridgeley) sandstone and Marcellus shale with numerous bare rock slopes and vertical cliffs. Ice Mountain lies on the west side of the Timber Mountain anticline and to the west of North Mountain fault, which places it on the Martinsburg allochthonous sheet. Ice Mountain is situated along North River and is known for the several hundred yards of ice that form at its base all year long. At its southern end overlooking the community of North River Mills is located Raven Rocks, a set of stone chimney outcrops. Raven Rocks is in height above mean sea level with vertical cliffs measuring nearly in height. Raven Rocks were named because of the presence of ravens during pioneer days. The present Raven Rocks is the remaining vestige of a once towering cliff that overlooked the North River. Geologically, Ice Mountain is a northern extension of North River Mountain.

[Q]: 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.

[Q]: Question: When was the company under with Smith recorded one of her songs being an answer record to label owner Roy Milton's own "R.M. Blues" founded? Passage:She married comedian, songwriter and record producer John Laurence Criner (1914–1992), and recorded several songs with Johnny Otis for the G&G and Gem labels, both parts of Criner's Royal Records group. She also recorded for Miltone Records in 1947, one of her songs being an answer record to label owner Roy Milton's own "R.M. Blues". During the 1950s, she recorded a number of tracks for Aladdin Records, including in 1953 the first version of "Dial That Telephone", a comedic monologue in which she complains to a friend about the absence of her husband. She also recorded with Ike Carpenter's orchestra. In 1955 and 1956, she recorded several tracks including "Champagne Mind With A Soda Water Income" with the Squires, a vocal group featuring Don Harris and Dewey Terry (later Don and Dewey). She recorded several versions of "Dial That Telephone" over the years, including a 1959 version released on Criner's Spot record label. However, the song only became a chart success in 1965, when a new recording on the Duo Disc label reached #36 on the Billboard R&B chart. In 1968, her recording of "Harper Valley P.T.A. Gossip", a spoken elaboration of the content of Jeannie C. Riley's hit "Harper Valley PTA", reached #43 on the R&B chart.
