On a standardized test, there is only one right answer. Every other answer is wrong. But educators know when students are engaged in authentic and meaningful tasks, they can arrive at answers that are not entirely wrong or entirely right.
This is real teaching. we should be raising and educating students to think outside the box and to figure things out on their own. they should be independent, creative and should be able to stand up for themselves. There is never just 1 answer or 1 way to get to an answer and we should be allowing our students to explore that and let them think on their own.
