Answer 1

The passage that best supports the idea that singing in rhythm is uncommon among animals is D. "...indris can keep a beat while singing. What other animals can do that? Only birds and the indris' toe-tapping distant cousins: people." This passage explicitly states that only birds and humans, in addition to indris, are able to keep a beat while singing, implying that this is a rare ability among animals.
