Answer:
Sexual competition often occurs within complex social environments where male displays can be received by potential mates, rivals, or both at once. In brown-headed cowbirds’ breeding flocks, for example, multiple males sometimes vie directly for a single female’s attention; at other times males have opportunities to sing to females without interference. It was tested whether cowbirds vary the intensity of their signalling across contexts like these. The songs were recorded from males courting females both with and without a male competitor in sight. The recordings were now played to solitary, naïve females in sound attenuation chambers, and also to a naïve aviary-housed flock. The songs males had produced when they could see their competitors were more attractive, eliciting more copulatory postures from naïve females and more approaches from birds in the flock.

Answer:
The monster in Mary Shelly’s Frankenstein lurches into life as big as a man but as ignorant as a newborn. He can’t read, speak, or understand the rudiments of human interaction. When he stumbles upon the cottagers, however, he picks up language by observing them and studying their speech. It is this acquisition of language, along with the eloquence it brings, that turns the monster from a mysterious nightmare into a sympathetic and tragic figure. By showing how language transforms the monster, and by contrasting the well-spoken monster with his equally articulate creator, Shelley argues that verbal communication—rather than action or appearance—is the only way through which people can truly understand one another.
