Final answer:
Pennsylvania was a key state for the Underground Railroad due to its geographical location and strong anti-slavery sentiment, debunking the claim that it was not a good state for the Underground Railroad.
Step-by-step explanation:
The claim that Pennsylvania was not a good state for the Underground Railroad to run through because it was a racist state is false. Pennsylvania was actually a key state for the Underground Railroad due to its geographical location as a border state between the North and South, as well as its relatively strong anti-slavery sentiment. The state's personal liberty laws and active abolitionist networks provided support and safe houses for freedom seekers. The state's conservative constitution during the Revolutionary Era does not indicate racial bias in its role in the Underground Railroad.
