Question

which of the following changes could be made to thunberg’s speech to the united nations to strengthen her speech?
○ using informal language to reflect her age
○ eliminating facts and statistics, which would be overwhelming to nonscientists
○ making the speech shorter to keep the audience focused on the main ideas
○ adding information about her credibility as a speaker to establish ethos

Explanation:

Greta Thunberg's UN speech aimed to persuade global leaders. Establishing ethos (credibility) is key to effective persuasion in formal settings like the UN. Adding credibility details would strengthen her authority, making the speech more impactful. The other options (informal language, eliminating facts, shorter speech) would weaken the speech's formality, evidence base, or clarity for the audience.

Answer:

adding information about her credibility as a speaker to establish ethos
