Children correctly learn the structurally-highest verb rule without hearing direct evidence that the simpler closest-verb rule is wrong.
4
In the generative grammar view, what enables children to correctly generalize syntactic rules without sufficient positive evidence?
An innate Universal Grammar that privileges hierarchical structure over linear order.
5
In the Bayesian LOT model of syntax acquisition, why do learners converge on the structurally-based rule for question formation?
The structural rule is considered the simplest or most efficient program, giving it a higher prior probability.
6
What operation on a set of strings is represented by the Kleene star, denoted as \$X^*\$?
The Kleene star generates the set of all possible finite concatenations of strings from the base set X, including the empty string.
