alleryIs x positive? (1) x > −3 (2) x is even
AStatement (1) alone is sufficient; (2) is not.
BStatement (2) alone is sufficient; (1) is not.
CBoth statements together are sufficient; neither alone is.
DEach statement alone is sufficient.
EStatements together are not sufficient.
Answer & Solution
Correct answer: C. Both statements together are sufficient; neither alone is.
1. (1) x > −3 includes 0. 2. (2) x even includes −2, 0. 3. Together: x even and >−3 → x ∈ {−2, 0, 2,…} still includes 0. Insufficient.
**Re-check:** needs strict positivity test.
Actually neither alone is enough
together still ambiguous → E. Correction: E.
