Question

Is \(x\) negative? Statements: (I) \(x^2>0\) (II) \(x^3\geq 0\)

• A. Statement (I) alone is sufficient to answer the question, but (II) alone is not sufficient.
• B. Statement (II) alone is sufficient to answer the question, but (I) alone is not sufficient.
• C. Both the statements (I) and (II) are sufficient to answer the question, but neither statement alone is sufficient.
• D. Both the statements (I) and (II) together are not sufficient to answer the question and additional data are required.

Hint:

Even powers remove sign information, but odd powers preserve sign. This is very useful in data sufficiency.
