DSE 2011 Question 54: IS-LM model

Setup, from Q52 of the paper:

Consider the fixed-price model: $C=C_{0}+c_{1}(Y-T)$ with $0<c_{1}<1$; $I=i_{0}+i_{1}r$ with $i_{1}<0$; $Y=C+I+G$; money demand $M^{d}=m_{0}+m_{1}Y+m_{2}r$ with $m_{2}<0<m_{1}$; and $M^{d}=M$. In this economy, an increase in $G$

(Same fixed-price model.) If $c_{1}$ is very close to 1, then an increase in $M$ has
