As a matter of fact, I picked up the concept from some other LSAT prep materials stating that "usually" = "most" ; "Often" "frequent" = "Some"
Am I lost or misunderstood? Plz correct me if I'm wrong.

You are correct but by "diagram" we mean Sufficient & Necessary statements. Quantifiers are not Sufficient & Necessary statements.

The statement "being successfully trained in speed-reading will usually be accompanied by an increased ability to concentrate" can be written out as follows:

STSR-some-IAC
IAC-some-STSR

This does not change the correct answer. Nor is it usual for that matter since this quantifier statement shares nothing in common with our Sufficient & Necessary statement.

Hope this helps! Please let us know if you have any other questions.

Can you please explain this in further detail? I do not understand how A is the answer to a Could Be True EXCEPT question.

I understand that "successfully trained in speed-reading" is not the same as "speed reading". So, wouldn't that mean that we cannot come to a conclusion with A? Meaning, A Could Be True?
