To correctly combine the two independent clauses "Jonas has homework" and "It isn’t finished" into a complete sentence, you can check the following options:
- Jonas has homework, but it isn’t finished. (Correct - this is a compound sentence using a coordinating conjunction)
- Jonas has homework that isn’t finished. (Correct - this changes the structure slightly but conveys the same idea)
- The homework that Jonas has isn’t finished. (Correct - rephrises the original clauses)
The following options are incorrect:
- Jonas has homework, it isn’t finished. (Incorrect - this is a comma splice)
- Jonas has homework; isn’t finished. (Incorrect - this is a sentence fragment)
Therefore, the correct ways to combine the clauses are options 1, 2, and 3.
