Consider the following statements about a polynomial $\mathrm { f } ( x )$ : I $\mathrm { f } ( x ) = p x ^ { 3 } + q x ^ { 2 } + r x + s$, where $p \neq 0$. II There is a real number $t$ for which $\mathrm { f } ^ { \prime } ( t ) = 0$. III There are real numbers $u$ and $v$ for which $\mathrm { f } ( u ) \mathrm { f } ( v ) < 0$. Which of these statements is/are sufficient for the equation $\mathrm { f } ( x ) = 0$ to have a real solution?
