Consider the following: Your friend, who is a linguistics major, has been up all night solving problem sets, her passion. Early in the morning, she says "I've been looking at the data all night and I think I've come up with a syntastic analysis—I mean syntactic analysis. Sorry, I'm so tired."
What is going on here?

B. This is an issue of linguistic performance: Your friend knows English grammar and recognizes that she has made a speech error.
C. This is an issue of linguistic competence: Your friend is able to construct sentences that are logically connected because she has memorized them.
D. This is an an issue of linguistic competence: Your friend has not acquired English grammar completely, but she is able to compensate for this deficit by laughing and correcting herself.
E. This is an issue of linguistic competence: It is clear to you what words your friend intended to say, but she does not know that she has made a mistake.
