Synonyms

Swan song refers to a final performance or work given before retirement or death. Choice B correctly identifies this meaning. Choice A incorrectly suggests it means the first work, while C and D are too narrow: a swan song can be any final creative work, not just poems or music.

To smear means to spread a substance across a surface, creating a mark or stain. Choice A correctly identifies this core meaning. The other choices, avoid, quarrel, and encourage, describe behaviors or conflicts, which have nothing to do with the physical action of smearing.
