Herman, Richards, and Woltz (1984) trained dolphins to understand hand commands. Their dolphins could understand five-sign strings, as well as some rules of language. For instance, their dolphins Phoenix and Akeakamai, understood the order words had to be in to perform a certain command. Choose the highest level that the animal may have attained. A. Phonology
B. Morphology
C. Syntax
D. Semantics
