Research on language development for deaf students who are in oral programs (that is, programs that teach deaf children a spoken language) has found that:
A. the vast majority of deaf children in these programs become able to speak and understand spoken language.
B. only a small percentage of deaf children in these programs achieve intelligibility in their spoken language or any reasonable understanding of it.
C. deaf children who are exposed to a sign language from birth are capable of learning to produce spoken language but deaf children without sign language exposure are not.
D. there are so few children who participate in oral programs that it is unclear whether or not they are effective.
Question 2
Research on children using American Sign Language (ASL) as their first language indicates that:
A. the children have fewer vocabulary words than their hearing peers at the same level.
B. the children have greater vocabulary words than their hearing peers at the same level.
C. deaf children make the same errors and learn language elements in the same sequence as hearing children.
D. deaf children make more errors, such as pronoun reversal, than hearing peers at the same level.
