Answer: The correct answer would be true.
Explanation:
An independent clause is found in a compound sentence and occurs when each clause can operate as a complete sentence in it's own right.

The sentence you construct would be a compound sentence and would read:
The journalist met a source at the hotel SO THAT he would get the facts for an article.
