Q: Extract the answer to the question from the following context. Question: The show that is the main topic of this passage is not of what category/genre? Context: The show's massive success in the mid-2000s and early 2010s spawned a number of imitating singing-competition shows, such as Rock Star, Nashville Star, The Voice, Rising Star, The Sing-Off, and The X Factor. Its format also served as a blueprint for non-singing TV shows such as Dancing with the Stars and So You Think You Can Dance, most of which contribute to the current highly competitive reality TV landscape on American television.
A: non-singing TV shows

Q: Extract the answer to the question from the following context. Question: What are alleles the recipe for? Context: Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.
A: protein

Q: Extract the answer to the question from the following context. Question: What would most people who are familiar with antennas consider to be common knowledge? Context: Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).
A: Resonant antennas are expected to be used around a particular resonant frequency

Q: Extract the answer to the question from the following context. 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.
A:
Lucius Varius Rufus and Plotius Tucca
