The negation of the statement "No slow learners attend this school" is: 
$\textbf{(A)}\ \text{All slow learners attend this school}\\ \textbf{(B)}\ \text{All slow learners do not attend this school}\\ \textbf{(C)}\ \text{Some slow learners attend this school}\\ \textbf{(D)}\ \text{Some slow learners do not attend this school}\\ \textbf{(E)}\ \text{No slow learners do not attend this school}$
The negation of the statement is basically the opposite of the statement, which is $\boxed{\textbf{(C) some slow learners attend this school.}}$
