Unfortunately, this test will not be able to receive a prize:
Too many missing explanations. More than 10 explanations simply repeat the correct answer. E.g.
#q36, #q35, #q34 etc
1) in many questions you didn't add an explanation, you just repeated what you said in the question and in the answer;
2) in all the "true or false" questions (except one) the answer is always "true". At the end I didn't even read the question and I selected "true" automatically. It would have been better if there was a better true to false ratio;
3) in questions 16 to 19 you ask about the picture that shows the diagram of heating curve. But in question 19 there is not the picture;
4) in questions 20 to 23 you ask the same question just using different words; in my opinion one qestion was enough.
