There are five possible answers to this "question".
Answer 1 "This is a way to judge your skills." This definitely could be correct...for me it is.
Answer 2 "This is a way to tease..." This could also be correct for some who have a bullying mentality...for me it is not correct.
Answer 3 " This is an easy and quick way to earn points..." This could possibly be correct but since only the top few are listed by name it seems unlikely for most...for me it is not correct.
Answer 4 "This is an opportunity to guess..." This seems okay at first but then it ends with "If wrong ONLY then you will read..." Sometimes that might be the case and sometimes not. This answer therefore can not be correct due to the absolute.
Answer 5 "This is an opportunity to learn..." Again this seems okay at first but then it ends with "...your answer will NEVER be wrong if you read the related subject first." That is definitely not the case as can be seen from the numerous record setting discussions about many different questions.
This means that Answer 1 has to be the correct answer.
