Question

________________________________ describe the role of a person's native language in simultaneously facilitating and interfering with second language acquisition.

a. cognitive principles
b. linguistic principles
c. executive principles
d. affective principles

Answer 1

I believe the answer is: linguistic principles
linguistic principles would regulate the framework in which an arrangement of words could be considered as 'acceptable' for a langage.
This would include things such as accordance with general principle (grammar) , syntax, and other language parameters.
