2. While researching a topic, a student has taken the following notes:
• The complex and extensive vocalizations of humpback whales are unique to them.
• These vocalizations have been informally dubbed as "songs."
• It is only the male humpback whales that sing these compelling songs during the mating season.
• These songs can last for up to 20 minutes and can be heard from many miles away.
• Marine biologists hypothesize that these melodious songs are instrumental in attracting mates or establishing their territory.
The student aims to highlight the purpose of these unique humpback whale songs. Which choice most logically uses relevant information from the research to accomplish this goal?
The second option most effectively underscores the rationale behind these unique humpback whale songs, signifying their possible roles in attracting a mate or marking territory during the mating season. While the other choices mention several characteristics of the songs, they do not explicitly elucidate their purpose.
