To determine which statement is true, I'll analyze each option:
-
Slavery was increasing in the South, especially in Washington D.C. - This statement would require evidence of growth in slave numbers in these regions, which might not be supported in historical context.
-
A majority of the House did not vote on California becoming a state. - This statement requires details of the voting records during California's admission process. Historically, California was admitted as a state in 1850 as part of the Compromise of 1850, and there was significant voting on this issue.
-
The Fugitive Slave Act helped the North and the Underground Railroad remove slaves from the South. - The Fugitive Slave Act was designed to aid in the capture and return of runaway slaves, making it actually detrimental to the Underground Railroad's efforts.
-
Slavery was decreasing in the area of Washington D.C. - The Compromise of 1850 allowed for the continuation of slavery in D.C. but also included the provision for gradual abolition. This statement could be true depending on the specific time frame and context.
Based on common historical knowledge, the most plausible true statement would be that slavery was decreasing in the area of Washington D.C.. However, the exact answer may depend on the specific data in the chart mentioned, which I do not have access to. Thus, if the chart indicates a trend of decline in slavery in Washington D.C., then the last statement would be the correct one.
