Can Be True EXCEPT

Is your explanation correct for this question? For example, the term can be equates to could be true. Since the question stem asks for the can be Except, the question asks for the logical opposite: the logical opposite of could be true is cannot be true. So, the correct answer cannot be true and the incorrect answers could be true. Please explain your must be true and logical opposite not necessarily true answer.

@Spring the key here is the word "inferred." An inference is something that "Must Be True."

Hence, the incorrect answer choices "Must Be True," while the correct answer choices are "Not Necessarily True."

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

Hi Instructor,

"inferred" does not mean what you say... I intuited that, and just researched it, "inferred", in the dictionary as well... so I feel it a sound argument to say you are wrong, unless there is a specific way of understanding the term within this course, which may be what you meant. Was it?

What is more, the question stem importantly uses the word "CAN" ... so unless your course is introducing modal logic with what "Can be Necessary" or "Necessarily could" (which I doubt), then the question should be understood as intuited: "can be 'inferred' except" should mean "what CAN follow from the premises/facts, except...". That is, as suggested by the user, the question is asking what cannot follow: what must be false.

Inferring does not require truth: inferences are not necessarily true, as one can surmise while inferring... contrary to how you explained.

Please fix the question/answer.


Thank you
