Answer:
c. both sequential and frustration mechanisms can promote responding during extinction.
Explanation:
Both sequential and frustration theories explain why there is increased resistance to extinction even when there should be extinction. The sequential theory explains that the subject's response increases when zero reward is followed by a reward intermittently so that the subject's memory of nonreward and reward trials boost response. In the same vein the frustration theory explains that a subject's response is increased with the partial reinforcement extinction effect whereby the subject is unable to notice when extinction begins(the discrimination hypothesis) and therefore keeps anticipating reward

Continental drift is the geological phenomenon in which continents move. These movements at speeds of a few centimeters per year can actually be measured since the advent of satellite geodesy. The movement of continents is caused by plate tectonics.
Alfred Wegener noted at the beginning of the 20th century that the edges of some continents (particularly South America and Africa) are similar in shape, concluding that the continents were connected and separated before. The problem was that it was not known how huge land masses could move across the Earth's surface. Such a movement requires enormous power and it was not known where it came from.
Later it was known that, according to plate tectonics, the continents move as a result of convection currents in the mantle. They slowly move away from each other, bump into each other, slide under each other, or rub against each other. This causes various surface phenomena, such as earthquakes, volcanism, and slow changes, such as subsidence, mountain building and the displacement of continents.

Explanation:
Californian authorities can arrest a driver under the age of 21 for driving under the influence of Alcohol if his/her BAC is 0.05% or higher. The illegal BAC percentage for a driver over the age of 21 is 0.08%.
But even less blood alcohol concentration is considered illegal. For example, for drivers under the age of 21, a BAC of 0.01% is enough to revoke their right to drive for a period of 1 year.
