: Please look at this sentence,"this document is sufficient to
raise red flags,but additional details were required".Does it mean
that this document is sufficient to call for people's vigilance?
: Thank you for your help!
To "raise a red flag" is to alert as to potential danger or trouble ahead, the origin being that red flags are often literally used to warn people of possible peril. Therefore yes, you're right - the document in question contained enough information to put the reader on his guard, but to be absolutely sure if his fears were justified, he required more details.
