Thanks a lot, DOC V. As you mentioned, I did make a mistake, when I wrote "The report fails to define what the term 'key issues' mean".
Here, as with my previous examples, "we", although a plural pronoun, represents a singular concept that requires a singular verb. Now, by putting "our conscious minds" in quotation marks, it should be clear that the same applies to that phrase; although it is a plural noun phrase, here it stands for "the phrase ''our conscious minds" or "the concept of 'our conscious minds'", either of which must be seen as singular.
That's what I suspected, and the reason I posted this question, here. You made it all clear.
Thank you again for you kind reply. DOC V. Have a good day!
