Final answer:
The new conflict in section 7 results from ongoing events in Kansas, known as Bleeding Kansas, a series of violent confrontations which heightened the sectional tensions and signified the escalation of the sectional crisis into a national one.
Step-by-step explanation:
Conflict Leading to New Tensions in Section 7
The new conflict mentioned in section 7 of the text is born out of the increasing sectional tensions between the North and the South. The Bleeding Kansas incident, in particular, signified a turning point where the sectional crisis escalated into a national one. The rising action of this period is highlighted by several pivotal events, but the specific event leading directly to a renewed conflict, as mentioned in section 7, appears to be the ongoing events in Kansas. Slavery, a contentious subject between northern and southern states, further fueled this division, especially after events like the Dred Scott decision which exacerbated the crisis.
