In the Monitor model, adults progress faster at first because they:

1. The Monitor model says only acquired language gives spontaneous speech. 2. Adults can apply consciously learned rules to check output before they have fully acquired the language. 3. Children rely mainly on acquisition and have little conscious rule knowledge. 4. Early on, adults therefore produce more correct utterances and can join conversations sooner. 5. A stronger inborn LAD is not part of the Monitor model, and the model does not say adults avoid thinking about form; they attend to it. 6. The correct choice is that adults use learned rules to self-correct. **Why the other options fail:** - A stronger inborn LAD is a Chomskyan idea and plays no part in the Monitor model. - Relying only on acquisition describes children, who have little rule knowledge. - Avoiding thought about form is the reverse, because the Monitor works only when the speaker attends to form. _Source: Wikipedia, "Input hypothesis", section "Monitor hypothesis" (revision 1380165607)_
