Problem: Question: "How did the replacement work?" Context: "The city's first bus rapid transit line, the Metrobus, began operation in June 2005, along Avenida Insurgentes. Line 2 opened in December 2008, serving Eje 4 Sur, line 3 opened in February 2011, serving Eje 1 Poniente, and line 4 opened in April 2012 connecting the airport with San Lazaro and Buenavista Station at Insurgentes.

Q: Question: "Which party did strong Republican areas disagree with during the civil war?" Context: "In the early 21st century, Republican voters control most of the state, especially in the more rural and suburban areas outside of the cities; Democratic strength is mostly confined to the urban cores of the four major cities, and is particularly strong in the cities of Nashville and Memphis. The latter area includes a large African-American population. Historically, Republicans had their greatest strength in East Tennessee before the 1960s. Tennessee's 1st and 2nd congressional districts, based in the Tri-Cities and Knoxville, respectively, are among the few historically Republican districts in the South. Those districts' residents supported the Union over the Confederacy during the Civil War; they identified with the GOP after the war and have stayed with that party ever since. The 1st has been in Republican hands continuously since 1881, and Republicans (or their antecedents) have held it for all but four years since 1859. The 2nd has been held continuously by Republicans or their antecedents since 1859." Answer:
A: the Confederacy

[Q]: Question: "What is controversial between branches?" Context: "Presbyterians distinguish themselves from other denominations by doctrine, institutional organization (or "church order") and worship; often using a "Book of Order" to regulate common practice and order.

Some of the splits have been due to doctrinal controversy, while some have been caused by disagreement concerning the degree to which those ordained to church office should be required to agree with the Westminster Confession of Faith, which historically serves as an important confessional document second only to the Bible, yet directing particularities in the standardization and translation of the Bible in Presbyterian churches." Answer:
****
[A]:
the degree to which those ordained to church office should be required to agree with the Westminster Confession of Faith
