Not completely sure of the topic, but I'll try here.

Allen has a photographic memory when it comes to remembering faces, so it was quite a surprise when a stranger asked, “Don’t you know me?” and Allen was forced to say “No.” The stranger issued a simple, “You’ll remember,” before leaving Allen’s store. The visit was familiar to Allen; he hated having such a strange gap in the memory he often boasted about. That evening at home, Allen perused every record of customer names and addresses he could find, hoping to spark his memory.

If there are specific answers or a rubric or anything like that, do not submit this, I only attempted to put the sentence together as an idea for you.

Allen has a terrible memory when it comes to remembering faces, so it was a challenge when a stranger asked, “Don’t you know me? and Allen was forced to say “No.” The stranger issued a simple, “you’ll remember,” before leaving Allen’s store. The visit was stressful to Allen; he hated having such an important gap in the memory he often boasted about. That evening at home, Allen perused every file of customer names and addresses he could find, hoping to spark his memory.

Explanation:

the sentence does not violate the phrase structure second rule (introduced by noam chomsky) because noun phrases consist of a determiner such as a, the or every, and a noun. in the sentence, the noun phrase the cake includes a determiner (the) and a noun (cake).

on the other hand, the first rule indicates that a sentence encloses a noun phrase, followed by a verb phrase. the example sentence can be analysed as follows:

john (n) + ate (v) + the (det) + cake (n).

just say it's your friend did it and you had no idea?
