Jake is a skilled toy maker who is able to produce both trains and balls. suppose jake buys a new tool that allows him to produce twice as many trains per hour as before, but it doesn't affect his ability to produce balls. what is the impact on jake's production possibilities curve?

The production possibility curve of Jake will pivot on the axis of trains.

Explanation: When there is a technological change in favor of one good, the quantity of that good produced with the same amount of resources increases. This means that there will be more trains being produced using the same amount of resources.  While, there is no change in the quantity of the of balls being produced.

Since there is no change in the quantity of balls the horizontal axis will not change.

well.. its gow babies are made

there was no passage listed but using the process of elimination i'd say it was d. the high economy would do the opposite. i don't see how low prices would affect it. high unemployment is possible but i feel d is the better answer.
