Query: Tilt and Tensor-to-Scalar Ratio in Multifield Monodromy Inflation   We study the possible range of the tilt $n_s$ and the tensor-to-scalar ratio
$r$ in multifield versions of a class of inflationary models from string
theory. We show that $r$ is the same between the single field models and
multifield models while $n_s$ is bounded above by the results of single field
models. Below its maximum value, $n_s$ depends on the specific distributions of
parameters in the model. The general trend is that the wider the distributions
are, the smaller $n_s$ is. We show that $n_s$ does not have a rigorous lower
bound. It is argued, however, that models predicting arbitrarily small $n_s$
only constitute a small portion of the possible ones and for the vast majority
of models, $n_s$ is bounded below by predictions given by models with uniformly
distributed parameters.
