Before revision:  Integrating out the latter, we derive the Fokker-Planck equation for the probability distribution of the former. This has the form of diffusion equation with time-dependent diffusion coefficient, resulting in an anomalous diffusion. The diffusion exponent can not be predicted using a simple scaling argument, and anomalous scaling appears as well .
After revision:  Integrating out the latter, we derive the long time behavior of the mean square displacement. Anomalous diffusion is found where the diffusion exponent can not be predicted using a simple scaling argument, and anomalous scaling appears as well .
