Question

which of the following beliefs did thomas jefferson use to justify the louisiana purchase? the purchase expanded federal power. the purchase would not impede states rights. the purchase required no federal authority.

Explanation:

To determine the correct answer, we analyze Thomas Jefferson's views and the Louisiana Purchase context:

• Jefferson, a strict constructionist, was cautious about federal power. The Louisiana Purchase was a constitutional gray area, but he justified it by arguing it wouldn’t infringe on states’ rights (since new territories could become states with their own rights).
• "Expanded federal power" contradicts his strict constructionist stance.
• "Required no federal authority" is incorrect, as the purchase needed federal action (treating it as a treaty - related power, for example).

Answer:

B. The purchase would not impede states' rights.
