Answer
x(t) = t^4/108 + 10t + 24, v(t) = t^3/27 + 10
I think the correct choice is D such that the sentence becomes: <span>Jan's speech was interesting and lively; Tim's was a bit too long. This is because semicolons are typically used to link two independent clauses that are very much related. In this case the two independent clauses are:
(1) Jan's speech was interesting and lively
(2) Tim's was a bit too long</span>
The answer is "always want to".
