The choices for this question are:
A) People could afford to eat beef.
B) An early marketing tactic suggested that pork was unhealthy.
C) Cattle were easy to raise.
D) Chickens were difficult to cultivate and raise.
The correct answer to this question is B, <em>An early marketing tactic suggested that pork was unhealthy</em>.
A variety of causes led to the success and increase of cattle raising after the Civil War. Because of the railroads, and the creation of cow-towns and the demand for beef in the North, the cattle raising became an interesting activity for those looking for work.
Among these causes, there are no registers of any marketing around pork being unhealthy. On the contrary, records show that pork packing in the Midwest grew around 1862-1871, thus B can't be correct.
