59. Based on the information in this passage, which of the following statements would the author most likely agree with?
(A) Rule-ordered processes of grammatical elements are the foundation of a language system.
(B) Language learning should base on a theory of language and refer to the psychology of learning.
(C) The phonological system defines phonemes, allophones, and phonotactics.
(D) Grammar is a branch of logic and the categories of Latin grammar represent ideal categories in languages.

In the passage, it says:

"The phonological system defines those sound elements that contrast meaningfully with one another in the language, their phonetic realizations in specific environments, and their permissible sequences."

• Phonemes are the sound elements that contrast meaningfully.
• Allophones are the phonetic realizations in specific environments (even though the term "allophones" isn't explicitly mentioned, this description aligns with it).
• Phonotactics refers to the permissible sequences of sounds in a language.

So, while the passage doesn’t explicitly list phonemes, allophones, and phonotactics by name, it describes these concepts accurately. That's why (C) is indeed the correct answer.

Thanks for pointing that out!
