When advanced ASL student Mariam wants to compare two things in ASL, she starts by signing one thing on her right side and the second thing on the other side. What is likely true about Mariam from the given information?

Based on the given information, it is likely true that Mariam is a CODA (Child of a Deaf Adult). This assumption is made because the way she is comparing two things in ASL (American Sign Language) by placing one on her right side and the other on her left side is a common technique used by fluent signers, indicating she likely has strong ASL skills and familiarity with the language and culture. The other options do not have enough supporting evidence from the provided information.
