Answer text and box are same colour, invisible to quiz taker

I created a short quiz and saved the draft, but when I looked at it, I couldn’t see any of the answers to pick from. The text and box are the same colour. I am using ARI Quiz and WP org. I have also tried changing the colour with Elementor, but it doesn’t let me go into the actual quiz page. How can I change the text colour?
