The sentences contain dependent clauses:
- 2. Alyssa is graduating next year, and so is my sister.
- 5. We’re leaving soon, so you’d better hurry if you want to go with us.
Explanation:
Clauses can be separated into two sorts: dependent and independent. An independent clause, alongside having a subject and action word, communicates a total idea and can remain solitary as a reasonable sentence. A dependent clause is a gathering of words that contains a subject and action word yet doesn't communicate a total idea.
A dependent clause can't be a sentence. This provision doesn't communicate a total idea and can't remain without anyone else as a sentence. For example, Alyssa is graduating next year, and so is my sister and We’re leaving soon, so you’d better hurry if you want to go with us.
