Answer:
variable-interval
Explanation:
In a variable-interval schedule, reinforcement is presented if the body emits at least one response after a variable interval of time. Generally, this scheme is represented by putting the average time of the variable interval. For example: VI-10min means that the booster is displayed after an average of 10 minutes and only for the first response issued.
The variable-interval schedule results in a high frequency of responses.

Answer:
False
Explanation:
America used canals and boat travel to move people and goods from the North to the South and vise-versa. Not from the East to the West. There were no large bodies of water, let alone rivers, to transport people and goods from the East to the West. This is why the idea of a transcontinental railroad was so attractive to America during the mid-19th century, after the invention of the steam engine. Railroads were fast and could conduct trade and transportation much quicker than most boats could, so after being built, railroads were the main method of transportation from the East to the West, and much conflict would arise in the coming future because of this.
