Input: Consider Input: Passage: In the second qualifying session, every driver set a lap on the option tyres except two. Lewis Hamilton still managed to take his McLaren into Q3 with the sixth fastest Q2 time on the prime tyres, and Pastor Maldonado, who did not set a timed lap. It was notable that Red Bull Racing and Ferrari needed to use options when Hamilton could use primes. Jaime Alguersuari – a man who had come from far back to score points a few times in , like his teammate did at this weekend set the slowest Q2 time and dropped out on the same row as Rubens Barrichello's Williams. Neither Renault made the top 10, Vitaly Petrov in 12th and Nick Heidfeld in 14th. One Force India and one Sauber failed to make the cut – Kamui Kobayashi (13th) joined Heidfeld on row 7, and similarly Paul di Resta just missed out with 11th.

Input: Consider Input: Passage: The government of the Electorate of Hesse (Kurhessen) had begun building the Frankfurt–Bebra railway from Bebra in North Hesse to Fulda, Hanau and Frankfurt before its annexation by Prussia after the Austro-Prussian War of 1866. The project was completed by the Prussian state railways on 15 December 1868. Until the opening of the line south of the Main, trains from Bebra to Frankfurt had to use the North Main line and the Frankfurt City Link Line. On 15 November 1873 the new line south of the Main between Hanau and Frankfurt via Sachsenhausen and Offenbach was opened, including South Station (opened as Bebraer Bahnhof, "Bebra line" station) and Offenbach Hauptbahnhof. The South Main line is still the most important rail link connecting Frankfurt with Leipzig, Berlin and Hamburg.

Output: Answer: 2


Input: Consider Input: Passage: Greek letter organizations (GLOs) first appeared at the university in 1847 when two men visiting from Yale University installed a chapter of Delta Kappa Epsilon. When DKE members began holding secret meetings in the old state capitol building that year, the administration strongly voiced its disapproval. Over a few more decades, 7 other fraternities appeared at UA: Alpha Delta Phi in 1850, Phi Gamma Delta in 1855, Sigma Alpha Epsilon in 1856 (this was the founding chapter), Kappa Sigma in 1867, Sigma Nu in 1874, Sigma Chi in 1876, and Phi Delta Theta in 1877. Anti-fraternity laws were imposed that year, but were lifted in the 1890s. Women at the university founded the Zeta chapter of Kappa Delta sorority in 1903. Alpha Delta Pi soon followed.
