A couple of weeks ago a student and I were talking about systems of public education. I asked, "What do you think about the quality of public schools in your city?" The student responded, "It depends of the situation." Can you find the problem in this sentence?
I addressed this topic in a video with PDF notes on my blog: http://goo.gl/PejU0v
Is the explanation clear? Do you have any questions? I am happy to help. :)
Yes, exactly. We even call this grammar topic 'dependent prepositions' as certain verbs such as 'to depend' rely on (depend on) one or a few prepositions.
'It depends on the situation' is the right sentence.
