Question

read the following text from a student essay. how can the writer best improve his or her ideas and development?
first and foremost, dont wait until the last minute to write your speech. having organized notes can help you remain calm. practice giving your speech in a mirror and pay close attention to your gestures and facial expressions. you can also practice in front of a friend or family member. think about what you want the audience to know; dont worry about what the audience is thinking about you. focus on breathing calmly. speak slowly, and create a rhythm with your words. when you appear relaxed and confident, you will be able to get your point across effectively.
by including more evidence to support the main idea
by stating the main idea clearly
by removing a second main idea

Explanation:

The essay gives tips on delivering a speech but lacks evidence (like examples, research, or personal anecdotes) to support the advice. Stating the main idea is not the issue as the tips relate to a central theme of effective speech delivery. There's no second main idea to remove. So adding evidence to support the main idea (effective speech delivery tips) is the best improvement.

Answer:

by including more evidence to support the main idea
