Hyperlink in contents are not underlined but we want them to be

Please see http://lovewordpress.com/what-we-do/hear-women-uk/. This is a hyperlink and I would like it underlined “• Psychological support and referrals for those at risk of gender-based violence, including female genital mutilation;” How do I make that happen?

I’ve tried a few things. Here is what I currently have in my Custom CSS.
