This question already has an answer here:
Sometimes in review section Stack Overflow tests us to find out that we are paying attention or not.
We can pass this test by clicking 'flag' if it says congratulation it is a test if it does not say so it is not a test.
And another way we can click 'edit' if it says this post cannot be edited so it means this is a test.
I'm asking the question. Is the test for checking if we are paying attention or not? So as I said a person can pass the test without paying attention.
