Which of the following pieces of evidence, if true, would suggest that the cortex is required for sentience in humans?
A)Human levels of sentience increase as the cortex develops.
B)People with Alzheimer's disease lose degrees of sentience as their neurodegeneration progresses.
C)The extent and characteristics of sentience in people with hydranencephaly can be predicted by cortex mapping.
D)People can suffer damage to subcortical areas without a noticeable impact on sentience.

The fact that the extent and characteristics of sentience in people with hydranencephaly (a condition where the cerebral hemispheres are absent and replaced with cerebrospinal fluid) can be predicted by cortex mapping suggests that the cortex plays a critical role in sentience. If the cortex is not present or sufficiently developed in individuals with hydranencephaly, it would likely impact their level of sentience. This is a stronger piece of evidence compared to the other options, as they do not directly address the role of the cortex in sentience.
