Answer:
The author of this poster clearly disagrees with the building of a railroad through Philadelphia. The author has used angry, violent language to describe railroads. Based on this language, the author seems to strongly feel that locomotives are harmful and may kill citizens who aren’t careful. Without knowing the author’s background, it is hard to know whether this opinion is biased or unbiased. The author may be biased by bad experiences with railroads, or may be making an unbiased statement about problems that railroads had in the past. However, because the author’s language is so angry and violent, this suggests that bias might be a problem.
