While researching conjectures and theorems, a student has taken the following notes: - In math, a conjecture is a statement that appears true based on examples. - A theorem is a statement that has been proven true by logical reasoning. - Students noticed that the sum of two odd numbers was even in every example they tested. - The teacher asked them to write a proof before calling the statement a theorem. - Examples can suggest a pattern but do not prove it for all cases. The student wants to distinguish a conjecture from a theorem. Which choice most effectively uses relevant information from the notes to accomplish this goal?
