What is understood by studying debate and delay on slavery together?

Correct answer: There was conflict between revolutionary ideals and colonial economy

The governing concept is historical interpretation through contrasting evidence. Debate on slavery shows that revolutionary language about liberty and equality challenged the legitimacy of enslavement. Delay in passing or enforcing abolition, however, shows that colonial plantations, merchants and other economic interests limited the application of those ideals. Reading both facts together prevents an overly simple claim that the Revolution instantly transformed every society. Option A is correct because it explains the tension between principle and profit. Options B, C and D are contradicted by the continued existence of enslaved labour and the resistance of commercial groups. The evidence therefore reveals both the reach and the limits of revolutionary change.
