\item ``a = raw\_input()'' and user enters ``2.5''.\\
What is the type of a?
\begin{itemize}
\item str
\item int
\item float
\item char
\end{itemize}
\vspace{5pt}
\item ``a = 2'' and ``b = 4.5''.
What is the result of the following action.\\
\verb~print ``a is \%d and b is \%2.1f'' \%(b,a)~
\begin{itemize}
\item a is 2 and b is 4.5
\item a is 4 and b is 2
\item a is 4 and b is 2.0
\item a is 4.5 and b is 2
