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 many square miles is the town where the route from West Virginia split? Passage:By 1947, present Interstate 70 across Pennsylvania was included in the planned Interstate Highway System. The route from West Virginia split at Washington, with one branch heading northeast to meet the Pennsylvania Turnpike near Pittsburgh and the other heading east, bypassing Pittsburgh to the south (via a planned bypass of Pennsylvania Route 71) to the New Stanton interchange. The piece south from the Breezewood interchange into Maryland was also in the network. The route between US 30 in Breezewood and US 522 in Warfordsburg was originally known as Pennsylvania Route 126. In 1957, preliminary numbers were assigned; the longer route via Pittsburgh (now Interstate 79 and Interstate 376) became the main line of I-70, while the southern bypass (now I-70) became Interstate 70S. The section of present-day I-70 between PA 519 near Washington and New Stanton was built as a four-lane divided highway known as the "Express Highway"; this road was assigned the temporary PA 71 Alternate designation in 1957 and would be designated as I-70S following the completion of additional connecting roads in the Interstate Highway System. On July 15, 1960, I-70 was designated onto the Penn-Lincoln Parkway. A southern extension of Interstate 79 (which had previously only run from Erie south to Pittsburgh) to Charleston, West Virginia in 1963 resulted in changes to I-70. On February 26, 1964, as part of the formation of Interstate 76 (east of downtown Pittsburgh), AASHTO approved a rerouting of I-70 along I-70S. The former I-70 became I-79 from Washington to downtown Pittsburgh and I-76 to and along the Turnpike to New Stanton. This brought the routing of I-70 to its present form.

Input: Consider Input: Question: How many years after Wish You Were Here was released was The Wall released? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.
