Final answer:
Delta Chi abolished Hell Week in the year 1929 as part of an effort to prevent hazing and create a safer environment for pledges.
Step-by-step explanation:
The year Delta Chi abolished Hell Week was 1929. Hell Week is a term commonly used to describe the period of time in which prospective fraternity members go through a series of rigorous, often intense initiation rituals. The practice has been controversial and has faced criticism for being hazing. Delta Chi, a law fraternity founded in 1890, took a stance against such activities early on. Over the years, other fraternities and sororities have also moved to abolish or modify Hell Week practices in an effort to promote a safe and welcoming environment for new members.
