Final answer:
An informative speech focuses on explaining or describing, while a persuasive speech aims to convince or influence. Speaking to persuade is more challenging due to the need for a compelling argument, evidence, and effective refutation.
Step-by-step explanation:
An informative speech is designed to explain, describe, or demonstrate while a persuasive speech aims to convince or influence the audience's beliefs, values, or behavior. Speaking to persuade is more challenging than speaking to inform because it requires the speaker to make a compelling argument, provide evidence, and effectively refute counterclaims. Persuasive speaking often requires appealing to emotions and using rhetorical techniques to sway the audience.
