Using transgenic mice, Wagner et al.'s 2017 study provided which of the following pieces of evidence that the cerebellum is involved with learning and predictive processes?
A)The cerebellum has more cells than the entire rest of the brain combined.
B)It is possible to perform calcium imaging on transgenic mice whose granule cells had been transfected with genes encoding fluorescent proteins.
C)Not only did the activity of certain cerebellar cells correspond with certain motor activity, but the activity of some cerebellar cells reflected trial outcomes.
D)Cerebellar cells directly affected motor cortex cells in a way that indicates that the cerebellum is involved with learning and predictive processes.

Wagner et al.'s 2017 study showed that some cerebellar cells' activity corresponded with trial outcomes, indicating that the cerebellum is involved with predictive processes in addition to motor activity. Choice A is incorrect because it is not relevant to the study's evidence. Choice B is true, but it does not provide evidence for the cerebellum's involvement in learning and predictive processes. Choice D is incorrect because the study did not show that cerebellar cells directly affected motor cortex cells, although it is possible that they are indirectly linked through other brain regions or circuits.
