'ask questions' is the definition.
'interrogate' can be an answer for 'ask' (interrogating is a kind of asking). I am unsure of the 'questions' bit.

'treating ore differently' is the wordplay.
'differently' is an anagram indicator.
'treating'+'ore'='treatingore'
'treatingore' is an anagram of 'INTERROGATE'.

'about' is the link.
