Correct option is B
The statements
B and C are
logically equivalent:
·
B. Some squares are not circles: This is a particular negative statement.
·
C. Some non-circles are not non-squares: This statement involves
double negation. When simplified, it is logically equivalent to "Some squares are not circles" (since the negations cancel out).
Information booster:
·
A. No squares are circles and
D. No circles are squares are
universally negative statements (they are logically equivalent to each other), but they are not equivalent to
B or
C, which are particular negative statements.
·
B and C represent particular negative statements, and
C is a double negation that simplifies to the same form as
B.
Additional Knowledge:
1.
Double negation can simplify a statement to its affirmative form. In this case, "Some non-circles are not non-squares" simplifies to "Some squares are not circles."
2.
Logically equivalent statements maintain the same truth value even when expressed with different phrasing or through logical transformations.
