The second or fourth one I'm not sure
Answer:
Patriotic songs have increased our morale in times of crisis, strengthened our resolve in eras of uncertainty, and rekindled pride in who we are, including what we represent, as a great nation.
Explanation:
1. D. Argumentation
Argumentative essays is a genre of writing where a certain topic is discussed, explored and inspected. It often makes use of empirical research. The writer then chooses a side on the topic, explaining his opinion on the matter in a compelling, evidence-based essay. It usually uses first person to make the writer's ideas and stand on the issue clear and concise.
2. B. Credible
Sources are the basis for informed opinion. Thus, it must be credible.
Choice E appears to be the best answer as it allows for an expansive essay that can focus on both positive and negative aspects of social media. The other choices would only encourage too much opinion or one-sided arguments, which would prevent the essay from developing into a thorough analysis.
