Submitting multiple thesis chapters for "two undergrad research papers" writing sample

[goghwithit]

I'm currently applying to several art history MA programs, and while most ask for one 15-20 page writing sample, one of them asks for "two research papers from undergraduate studies." I have taken a chapter from my senior thesis and formatted the intro/conclusion/necessary information to make a coherent research paper, but now I don't know what to do for the second writing sample. Should I frame another chapter from my thesis as a stand-alone research paper, or revise one of my research papers from another art history undergrad course -- written with much less supervision and revision.

Thank you for any help or advice on this question!!
