Product Risk Quiz on binance.com, why are my answers wrong?

I'm trying to fill out the product risk quiz and the website tells me I'm wrong, why ?

The questions are (translated from German):

• What have you invested in?
  • my answer: nothing
• What volume have you traded within the last three years?
  • my answer: less than 1.000
• How often have you traded
  • my answer: seldom
• (I hope up until here there were actually no wrong answers...)
• What can influence the value of your investment portfolio? (multiple choices)
  • [X] Exchange rate
  • [X] Fluctuations in stock price
  • [X] Bankruptcy
  • [ ] None of the above
• How low can the stock price fall?
  • [ ] 25%
  • [ ] 50%
  • [X] 100%
  • [ ] The stock price never falls

I am at a loss why my answers are supposed to be wrong, I suspect the website is broken. Or could maybe someone more knowledgeable point out my errors?
