What incidents and events increased southern fears concerning growing northern hostility toward the southern way of life How correct was the South in these fears?

well it's very easy to determine. The incidents and events were fears of not wanting to do their own work nor study. The south was correct in these fears because you had to waste your time in trying to cheat and not do your own homework.

I'd just like to say that sometime homework is either gruelingly long or nearly impossible. I had an assignment where I had to virtually write 35 essays and this was one of the prompts, and if you don't remember the era for any of the essay questions it's near impossible to do. So please don't be rude and waste people's time answering answers in such a USELESS way.

The failure of the Mexican-American war, Bleeding Kansas, the Lecompton Constitution's lack of effectiveness, and other generally disunionizing factors affected the hostility felt by the South. The South was correct, obviously, by the fact that it lead to a Civil War (over state's rights, yes, but states rights about SLAVES).
