What selector should be used to change the font-size?

Question

css

There is a site:
site
What selector should be used to increase the font size only in this block?

As I understand it, I need to apply font-size to the link.
It's confusing that on this page there are 2 classes named box-content (one with categories and one with text information) And if I start writing: box-content > div > ul > li > a, I'm not sure if it will work
Manually, prescribe a class for each link ... It will be very long)

Answer 1

.box-content:first-child ul a{
    font-size:18px!important;
}
