The following terms are equivalents:
- Must Be True = Cannot Be False
Not Necessarily True = Could Be False
Could Be True = Not Necessarily False
Cannot Be True = Must Be False
This info helps decode the various things that the test makers tend to ask in questions. Collectively, these also cover the range of possibilities in situation dealing with truth. For me and for most students, thinking in Flaw tends to be tougher, so I automatically translate any term in False into it's True equivalent. So, if I get an LG question that says, "Which one of the following Must Be False, I instantly convert that to it's True equivalent, which is Cannot Be True. Then I know the right answer will be "Cannot Be True," and any wrong answer Could Be True (which allows for Must Be True).
Does that help? Please let me know. Thanks!
