Question: What year did Philby defect? Passage:In May 1986, Souther requested Soviet citizenship, aware that the investigation against him was progressing. In June, fearing imminent arrest, Souther defected to the Soviet Union by flying from the United States to Rome, where the Soviet intelligence services transferred him to Moscow. Initially, Soviet counterintelligence units were suspicious of Souther's defection and feared that he was a double agent for the CIA, but he was cleared shortly afterwards. On 2 October 1986, Souther was granted Soviet citizenship in a decree from the Presidium of the Supreme Soviet, and adopted the Russian name Mikhail Yevgenyevich Orlov. Souther was well-received by the Soviet authorities, gifting him an apartment in Moscow and a dacha on the outskirts of the city, and promoting him to the rank of major in the KGB one of few foreign spies to be commissioned as an officer in the agency. Souther became actively engaged in scientific activities, developed his own English teaching program, walked around Moscow a lot, and travelled to other Soviet cities.

Question: How tall is the mountain range that Muleshoe is at the foot of? Passage:Muleshoe is situated on the Great Plains in an area where the plains reach their highest altitude at the foot of the Rocky Mountains known as the High Plains; more specifically, it is located on the South Plains in a region known as the Llano Estacado. The area topology is gently rolling plains with a large number of playa lakes on top of a large plateau. Many of the playa lakes have dried out due to the water exploitation of the Ogallala Aquifer that helped supply water to the lakes during dry seasons. Soil types vary from dark brown playa-lake silt to iron-rich clay to sandy soil; topsoil and subsoil layers vary, as well. Most of the area contains a layer of caliche; in some areas, no topsoil or subsoil reveals the layer of caliche, while other places have up to 4 ft of topsoil or subsoil combined.
