SAT writing help please!

<p>In scenarios reminiscent of the old science fiction movie Fantastic Voyage, medical researchers HOPE EXPLORING the body with miniature robots sent into the bloodstream.</p>

<p>a. hope exploring
b. hope to explore</p>

<p>The answer is B. Why? I can see how B sounds more right...but is there any more concrete reason than that?</p>
