LR Question 15 Explanation

QUESTION TEXT: Babies who can hear and have hearing parents who expose…

QUESTION TYPE: Must be False

FACTS:

1. Babies who can hear and have parents who can hear will start babbling at an early age. It’s a precursor to speaking.
2. Deaf babies with deaf parents will start babbling in signs at an early age.

ANALYSIS: We’re trying to prove one of these answer choices wrong. It has to be directly contradicted by the stimulus. It has to be impossible if the information in the stimulus is true.

___________

1. The stimulus didn’t mention names or what words babies use first.
2. CORRECT. The stimulus disproves this thesis. The deaf babies are able to start using language even though they aren’t using their vocal tracts.
3. We have no idea. Our only examples are of babies who communicate with adults.
4. We have no idea if the babies are aware of the usefulness of babbling.
5. We don’t know if this is false. We know that hand gestures are significant for deaf babies. But they might be linguistically significant for babies who can hear too.
