Input: Consider Input: Passage: In February 1861, secessionists in Tennessee's state governmentled by Governor Isham Harrissought voter approval for a convention to sever ties with the United States, but Tennessee voters rejected the referendum by a 5446% margin. The strongest opposition to secession came from East Tennessee (which later tried to form a separate Union-aligned state). Following the Confederate attack upon Fort Sumter in April and Lincoln's call for troops from Tennessee and other states in response, Governor Isham Harris began military mobilization, submitted an ordinance of secession to the General Assembly, and made direct overtures to the Confederate government. The Tennessee legislature ratified an agreement to enter a military league with the Confederate States on May 7, 1861. On June 8, 1861, with people in Middle Tennessee having significantly changed their position, voters approved a second referendum calling for secession, becoming the last state to do so. Question: Which area of Tennessee was most resistant to secession?

Output: East Tennessee

Input: Consider Input: Passage: Starting in 1965, Donald Davies at the National Physical Laboratory, UK, independently developed the same message routing methodology as developed by Baran. He called it packet switching, a more accessible name than Baran's, and proposed to build a nationwide network in the UK. He gave a talk on the proposal in 1966, after which a person from the Ministry of Defence (MoD) told him about Baran's work. A member of Davies' team (Roger Scantlebury) met Lawrence Roberts at the 1967 ACM Symposium on Operating System Principles and suggested it for use in the ARPANET. Question: What did Davies want to build

Output: proposed to build a nationwide network in the UK

Input: Consider Input: Passage: Burdened with debt, in 2004 Vivendi Universal sold 80% of Vivendi Universal Entertainment (including the studio and theme parks) to General Electric, parent of NBC. The resulting media super-conglomerate was renamed NBCUniversal, while Universal Studios Inc. remained the name of the production subsidiary. After that deal, GE owned 80% of NBC Universal; Vivendi held the remaining 20%, with an option to sell its share in 2006. GE purchased Vivendi's share in NBCU in 2011 and in turn sold 51% of the company to cable provider Comcast. Comcast merged the former GE subsidiary with its own cable-television programming assets, creating the current NBCUniversal. Following Federal Communications Commission (FCC) approval, the Comcast-GE deal was closed on Jan 29, 2011. In March 2013, Comcast bought the remaining 49% of NBCUniversal for $16.7 billion. Question: In what month and year did Comcast buy 49% of NBCUniversal?
Output: March 2013
