Final answer:
The fraternity's magazine being called The Rainbow cannot be deemed true or false without knowing the specific fraternity in question. The name can vary widely among different organizations.
Step-by-step explanation:
Various fraternities, sororities, and other organizations may have publications with different names. For instance, ONE Magazine was a significant publication in the history of LGBT rights and was the first to reach a national audience, challenging the status quo and addressing issues like same-sex marriage and anti-LGBTQ persecution. In the context of African-American fraternities, literature like Carol Branch's Steppin’ Through These Hallowed Halls might offer insights into specific fraternity cultures, but does not provide a definitive answer to the name of a fraternity's magazine.
