Final answer:
Gender ratios at high-risk fraternity parties generally favor men, contributing to environments where women can be more vulnerable to sexual intimidation and violence.
Step-by-step explanation:
At high-risk fraternity parties, the gender ratios are typically skewed in favor of men. This skewing of ratios can be attributed to both cultural influences and explicit strategies employed by some fraternities. Certain fraternity members have been known to use their control over social events to create environments where women are outnumbered and more vulnerable, facilitating forms of sexual intimidation and violence. Fraternity culture and the problems of sexual assault on college campuses are complex issues that have prompted institutions to take action through awareness training and the establishment of support systems for survivors.
