I am uncertain about the terms "determine [something]" and "determine on [something]." These words seem to have similar meanings, but possibly with different connotations. Consider this example:
What determines whether you are a career success or a failure?
In this sentence I'm puzzled by the difference, if any, between "determines whether" (which the sentence uses) and "determines on whether" (which it doesn't). How do the meaning of the two wordings differ in sense?
