How does this work: fact checking: choose answers to 25 questions

Hi,

One batch is about fact checking (a batch you can earn by giving relevant information about places on Google to others). I noticed I have a 0 on ‘Answers’ - ‘Select answers to 25 questions 0/25’.

I already have 138 approved changes and 167 verified changes, but 0 selected answers.

I don’t know how this works… How or where can I do this?

Happy guiding,

Richard
