Has anyone else experienced an issue where they are sure they are answering a question correctly but it is marked as wrong?

Can someone help me figure out why I keep getting one question wrong on the GCS Field Research Exam? I have even went back and changed my answer several times because I still got it wrong.

Thank you for any input you have on this one!

Serene

Post a screenshot of the error you're getting, it's usually because of a previous answer though.

What is a GCS Field Study Exam? Can you please share? I am new here. Thanks!
