Final answer:
The subject in the student's question is 'Jen' and the verb is 'peruses'.
Step-by-step explanation:
The student is asking a question related to subject-verb identification in English. In the provided text fragment, "JenperusestheracksofsummerdressesbutnonecatcheshereyeSheprefersplayfulunconventional"—after fixing the typos—the sentence should be: "Jen peruses the racks of summer dresses but none catches her eye".
