If Mary's neurons were never able to achieve a potential more positive than -70 millivolts, ____.
A) her action potentials would be very slow
B) she would not be able to generate any action potentials
C) her action potentials would be very inconsistent
D) she would be able to move, but she would not be able to think

The threshold potential for generating an action potential in neurons is typically around -55 millivolts. If Mary's neurons were never able to achieve a potential more positive than -70 millivolts, they would not be able to reach the threshold and generate any action potentials. This would likely severely impair her ability to communicate and move effectively.
