u/Uneternalism

I just failed a concept because all 3 questions were highly ambiguous. And it's not the first time I encountered these types of questions, but the first time I got unlucky and picked the wrong one of the two answers I was questioning. Is there any way that they reset your answers, or do you just have to live with this unfair grading? This is really annoying, and I noticed it in multiple questions now. How is it so hard to provide clear answers that reflect what you learned?

I have over 10 years of experience in this topic I'm doing right now, and I still got all 3 questions wrong. This is how badly they are phrased and illustrated.
