Thanks :)

The first is correct, but the second is not.

Big clue in the second = " ... , but ... " AND 2 separate subjects, each with its own verb.

Although he was born in Scotland,<~~dependent clause he became a hero of the American Revolution. <~~independent clause

COMPLEX

His ship was badly managed,<~~independent clause but Jones refused to give up. <~~independent clause
COMPOUND

So the second one is a compound sentence?

Yes, that's right ... compound.

Although he was born in Scotland, he became a hero of the American Revolution is a complex sentence.

His ship was badly managed, but Jones refused to give up is a compound sentence.

Great job! You got the first question correct. "Although he was born in Scotland, he became a hero of the American Revolution" is indeed a complex sentence. It contains both an independent clause ("he became a hero of the American Revolution") and a dependent clause ("Although he was born in Scotland") connected by the subordinating conjunction "although."

For the second question, your answer is incorrect. "His ship was badly managed, but Jones refused to give up" is a compound sentence. It consists of two independent clauses ("His ship was badly managed" and "Jones refused to give up") connected by the coordinating conjunction "but." In a compound sentence, each independent clause can stand alone as a complete sentence. Therefore, it is a compound sentence.

Keep up the good work! If you have any more questions, feel free to ask.
