Pennsylvania was able to raise only one battalion to send to the army.
a. true
b. false

The correct answer for this exercise is: False.

Explanation:

First of all, I don't know what war you are talking about in this army case scenario. So I recommend you that the next time you write your question with more information so we can contextualize better.

However, I do know that if we are talking about the revolutionary war, Pennsylvania was a very important force provider with the Pennsylvania line that provided more than thirteenth regiments and more independent specialized companies. Considering the modern American army organization each battalion has no more than 3 companies. If the Pennsylvania line was composed of thirteenth companies well, there were at least 4 regular battalions.

On the other hand in the Civil war, Pennsylvania provided more than 360 thousand men, if we consider the regular batallion to be composed by one thousand men. Well, Pennsylvania sent around 360 battalions.

Thus the correct answer is false.
