Question

In Côte d'Ivoire practically no one still practices traditional African religions, including ancestral worship

Answer 1

The answers are false and false. And they are both correct.

Answer 2

Well, this is not an easy question, as it's hard to say what " practically noone" means. 

In Cote D'Ivore, most people are either Muslim or Christian, so it's definitely true that most people are not practicing traditional religions. 

However, an estimated 3-10 percent of the population still practices traditional religions and some fuse elements of traditional religions with Christianity or Islam. 

So I would judge the statement as "false" that "practically noone" - since some people do!
