I didn't notice this when I first took this quiz before, but today, when I took the quiz for the second time, it caught my eye. When I go to answer other questions of the quiz when I click on any of the four options if the option is correct there is a green signal but if I click on the wrong option then there is a red signal but when I click on this question there is no signal. (green and red). I am very interested to know what the secret behind this could be.
Like you I didn't notice it that way at first but when you posted I went back to answering this question on the quiz to double check. But to answer this question here is exactly what you said. When answering other questions, if the answer is correct or if the answer is colored, it is explained through various indicators, but no matter what option I click on this question, there is no indication here. And I don't even understand what the real answer is here. But I think forty languages are officially translated in the Bitcoin white paper. Hope @GazetaBitcoin will explain everything about this.
