 \subsubsection{Exercise 2}
 For this exercise you should create a new proplem file analogous to
 the file \texttt{tutorialproblem\_coupled.hh} and new spatial parameters 
-just like \texttt{tutorialspatialparameters\_coupled.hh}. These files need to
+just like \texttt{tutorialspatialparameters\_coupled.hh}. The new problem file needs to
 be included in the file \texttt{tutorial\_coupled.cc}. 
 
 The new file defining spatial parameters should contain the definition
