Question: Passage: Garland has tended to favor deference to regulatory agencies. For example, in In re Aiken County (2013), Garland dissented when the court issued mandamus ordering the Nuclear Regulatory Commission to process the Yucca Mountain nuclear waste repository license. In Americans for Safe Access v. Drug Enforcement Administration (2013), Garland joined a divided court upholding the DEA's classification of marijuana as a Schedule I drug. However, according to Goldstein, in a number of split decisions on environmental law Garland "favored contested EPA regulations and actions when challenged by industry, and in other cases he has accepted challenges brought by environmental groups." In Rancho Viejo, LLC v. Norton (2003), Garland found the arroyo toad was protected by the federal Endangered Species Act. Then-Circuit Judge John Roberts dissented from the denial of rehearing en banc, writing that Congress's interstate commerce power cannot reach "a hapless toad that, for reasons of its own, lives its entire life in California."

Question: 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.

Question: Passage: With the ascendance of Simeon I to the throne in 893, the long-lasting peace with the Byzantine Empire established by his father was about to end. A conflict arose when Byzantine Emperor Leo VI the Wise, acting under pressure from his wife Zoe Zaoutzaina and her father, Stylianos Zaoutzes, moved the marketplace for Bulgarian goods from Constantinople to Thessaloniki, where Bulgarian merchants were heavily taxed. Forced to take action, in the autumn of 894 Simeon invaded the Byzantine Empire from the north, meeting little opposition due to the concentration of most Byzantine forces in eastern Anatolia to counter Arab invasions. Informed of the Bulgarian offensive, the surprised Leo sent an army consisting of guardsmen and other military units from the capital to halt Simeon, but his troops were routed somewhere in the theme of Macedonia.The Magyars managed to defeat Simeon's army twice, but in 896 they were routed in the Battle of Southern Buh. The war ended in 896 with a great Bulgarian victory near Bulgarophygon in Eastern Thrace. The market was returned to Constantinople, and the Byzantine Emperor had to pay annual tribute to Bulgaria. More importantly, with help from the Pechenegs Simeon successfully fended off a Magyar invasion, which was coordinated with the Byzantines.
