Final answer:
Webster believed in preserving the Union, while Calhoun advocated for secession. option B is correct
Step-by-step explanation:
Webster's views on U.S. history, particularly the relative strength of the Northern and Southern sections, differ from Calhoun's in the following way: Calhoun advocated for secession and believed that the North was impeding southern prosperity by limiting the spread of slavery.
I suggested the concept of a dual presidency to represent the North and the South. On the other hand, Webster believed in preserving the Union and called for national unity. He argued against threats of disunion and endorsed a federal law to ensure the return of escaped enslaved people. Therefore, option b) Webster believed in preserving the Union, while Calhoun advocated for secession is the correct answer.
