What do 2 and 7 have in common?

I have read this evening that this (question in heading) is sometimes used as a screening question as autistic people tend to have a different interpretation to neurotypical people. Just wondering what people's answers would be and whether you're autistic or not. I and my friend both are and we both gave the answer usually given by autistic people. 

Also, if anybody knows of any other similar questions or tests, or places where I can look for them, please let me know. I am utterly fascinated!

  • They're both prime numbers. (My answer may have been influenced by someone else giving that answer though.) Without spending more time thinking about it the best I could come up with other than that was they're both whole numbers and they're both single digit numbers.
