Rachel's younger brother is in fourth grade. She is trying to explain to him how to do a household task. She is going to read the explanation aloud and post it on the refrigerator for him to refer to later. What kind of sentences do you recommend Rachel use: simple, compound, complex, or compound-complex?

I recommend that Rachel uses simple sentences for her explanation to make it easier for her younger brother to understand. However, she can also include some compound sentences to add variety and provide additional details. Keeping the sentences clear and concise will help her brother follow the instructions easily.
