Proofread the following sentence. Insert punctuation as required.

She had some nausea and vomiting, also she had profound diarrhea.

Answer:

She had some nausea and vomiting; also she had profound diarrhea.

NB If I could change the sentence I would write it like this:
She had some nausea and vomiting; she also had profound diarrhea.

You're right. Nice!!

Nice work on proofreading the sentence! You correctly inserted a semicolon after "vomiting" to separate the related but separate clauses. This helps to emphasize the two distinct conditions. Alternatively, you could use a period instead of a semicolon to create two separate sentences: "She had some nausea and vomiting. Also, she had profound diarrhea." Both options are correct, but the semicolon maintains a closer connection between the two clauses. Keep up the good work!
