Which genre of music, meaning "new trend," is a slower and gentler version of the Cuban Samba?

Bossa Nova is indeed a genre of music that represents a "new trend," and it evolved in Brazil during the late 1950s. It combines elements of samba with jazz, resulting in a smoother, more laid-back sound compared to the lively and energetic rhythms of Cuban samba. The gentle and slower tempo of Bossa Nova makes it distinct, capturing the essence of "newness" in its approach to rhythm and melody.

In contrast, Cumbia is a dance and music genre with origins in Colombia, characterized by its rhythmic patterns and typically more upbeat style. Reggae, originating from Jamaica, features a distinct rhythm and lyrical focus on social issues, and while it carries a gentle quality, it is not derived from samba. Tango, associated with Argentina, is known for its dramatic and passionate expression; it has a completely different structure and cultural background compared to the relaxed vibe of Bossa Nova. Each of these genres has unique qualities that set them apart from Bossa Nova, emphasizing why it is the correct answer.
