it is the best structure to use to convince the audience to take specific actions to solve the problem of climate change, which is her purpose for this speech.

Explanation:

Greta Thunberg's speech at the U.N. Climate Action Summit aims to show the negative effects of climate change (causes) and how they lead to consequences, and using cause - effect helps present this to achieve her purpose of getting action. Let's analyze each option:

• Option 1: Cause - effect isn't about showing steps to restore the environment, so this is wrong.
• Option 2: Her speech isn't about comparing how countries handle climate change, so this is wrong.
• Option 3: Cause - effect is good for showing negative effects of climate change (causes and their effects) to support her purpose of getting action, this fits.
• Option 4: While convincing to act is her purpose, the key is the cause - effect structure showing negative effects to drive action, option 3 is more accurate about the structure's role.

Answer:

It is the most logical structure to use to present the negative effects of climate change, which helps her accomplish the purpose of her speech.
