Answer:
False
Step-by-step explanation:
Modern vocabulary language has evolved over time, they're words people used to use decade ago that humans no longer use today. Just because a sources vocabulary is different from modern language doesn't mean that the sources information is invalid. It all depends on the topic you are working on; some old source information could be primary source material but may have different vocabulary then we use today. It is not a good idea to quote a source whose style and vocabulary are different from modern American usage is a "false statement" or the second option.
