Most Strongly Supported vs. Inference vs. Must be True

Question

The questions stem for each of the different types of questions is as follows:

Most Strongly Supported:  The statements above, if true, most strongly support which of the following?

Inference:  Which of the following can be inferred from the argument above?

Must Be True:  Which of the following must be true?

My understanding is that there is no difference between Inference and Must be True question. For both these question types you have to find an answer option that should 100% be true from the premises of the argument. The other four wrong options won't be 100% true from the premises.

But, for the question type 'Most Strongly Supported', the answer could be 'Must Be True' or 'Most Likely To Be True'. It means we may have to differentiate between two options that seem like an answer but only one of them is more likely to be true from the premises.

Am I correct in my understanding?

Dear gmatter0913 , I'm happy to respond. :-)

For all practical purposes, those three questions are quite similar. It's true that the last two are looking for something that absolutely has to be true, and the first is looking for something that either is likely to be true or must be true. In this sense, the first prompt allows for a little more latitude in terms of possible answers. The important point, though, is you will not have to make this choice when you are solving an individual GMAT CR question. If the first prompt appears, then one answer choice will be in that "must be true" or "very likely to be true" category, and each of the other four will be clearly wrong. If the second or third prompt appears, only one answer will be something that absolutely, unavoidably, has to be true, and among the other four answers, some of them will be in the "possibly true" or "probably true but not necessarily" categories, and these will be wrong answers for these prompts.
