This might be a strange question but basically I am wondering the following:
If I wish to integrate a quotation into my sentence and in the original text there is a "the" or "a" or "that" before the start of the bit I want to quote directly but the same words are also those I wish to use in my sentence grammatically, do I need to include the "the" or "a" or "that" in the quotation?
To give an example if the original sentence is "I hereby declare that time is relative". Can I then say in my sentence: After Einstein paused for a second he explained that "time is relative". Or am I bound to include the "that" as well? The thing is I have kind of seen both in the writings of historians (that is my academic field) it seems (not with "that" I think but with "a" and "the" for sure, meaning that some include it in the quotations and others don't). And what about "that a" or "that the" being before the bit I wish to quote?
