Q: Question: "Who published the poem?" Context: "According to the tradition, Virgil traveled to Greece in about 19 BC to revise the Aeneid. After meeting Augustus in Athens and deciding to return home, Virgil caught a fever while visiting a town near Megara. After crossing to Italy by ship, weakened with disease, Virgil died in Brundisium harbor on September 21, 19 BC. Augustus ordered Virgil's literary executors, Lucius Varius Rufus and Plotius Tucca, to disregard Virgil's own wish that the poem be burned, instead ordering it published with as few editorial changes as possible. As a result, the text of the Aeneid that exists may contain faults which Virgil was planning to correct before publication. However, the only obvious imperfections are a few lines of verse that are metrically unfinished (i.e. not a complete line of dactylic hexameter). Some scholars have argued that Virgil deliberately left these metrically incomplete lines for dramatic effect. Other alleged imperfections are subject to scholarly debate." Answer:
A: Lucius Varius Rufus and Plotius Tucca

Q: Question: "Where is the partnership for Southminster Presbyterian Church located?" Context: "African Presbyterian churches often incorporate diaconal ministries, including social services, emergency relief, and the operation of mission hospitals. A number of partnerships exist between presbyteries in Africa and the PC(USA), including specific connections with Lesotho, Malawi, South Africa, Ghana and Zambia. For example, the Lackawanna Presbytery, located in Northeastern Pennsylvania, has a partnership with a presbytery in Ghana. Also the Southminster Presbyterian Church, located near Pittsburgh, has partnerships with churches in Malawi and Kenya. The Presbyterian Church of Nigeria, western Africa is also healthy and strong in mostly the southern states of this nation, strong density in the south-eastern states of this country. Beginning from Cross River state, the nearby coastal states, Rivers state, Lagos state to Ebonyi and Abia States. The missionary expedition of Mary Slessor and Hope Waddel and their group in the mid 18th century in this coastal regions of the ten British colony has brought about the beginning and the flourishing of this church in these areas." Answer:
A: Malawi and Kenya

Q: Question: "What element comes into play?" Context: "Semi-additive is the most common process: The unpatterned board has a thin layer of copper already on it. A reverse mask is then applied. (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces.) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied. The mask is stripped away and a brief etching step removes the now-exposed bare original copper laminate from the board, isolating the individual traces. Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards." Answer:
A: copper

Q: Question: "Which one is softer, brass or copper?" Context: "The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a pure metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics." Answer:
A:
Copper
