Final answer:
The most persuasive speech is likely Obama's because of its formal nature and specific purpose as a former president's address.
Step-by-step explanation:
Introduction:
The speeches given by Corden and Obama have different purposes and contexts. Corden's speech is likely from a late-night talk show, where he engages with his audience in a humorous and entertaining manner. Obama's speech, on the other hand, is likely a formal address delivered during his time as President of the United States.
Most persuasive speech:
The most persuasive speech would likely be Obama's because it is more likely to be focused on a specific issue or topic of national importance. As the former president, Obama's speech would be expected to use compelling reasons, evidence, and an argument that is well-researched and supported.
Conclusion:
While both speeches may have their own merits, Obama's speech is more likely to be the most persuasive due to its formal nature, specific purpose, and the weight of his position as the former president.
