Hello there!
1. You use rhetorical devices to help persuade a reader. The indented effect is that the audience is successfully persuaded to do, or believe in what you are trying to get them to.
How did I get this answer? By googling "rhetorical devices" I learned that they were a "persuasive device, or stylistic device is a technique that an author or speaker uses to convey to the listener or reader a meaning with the goal of persuading them." This means they're used in persuasive writings, to persuade a writer into believing something the author does.
2. There have been many times recently where people are starting to speak up about cultural issues. Some more mainstream ones include racial inequality and the fight for racial equality, fight for women's rights and equality and fight for LGBTQ+ rights.
How did i get this answer? Staying up-to-date on what's going on in the news and on social media can help you get a better understanding of social issues.
I hope this helps, and have a great day! Please don't hesitate to ask if you need more help with this specific question!
