Are there instances of papers the first parts of whose colon-wise titles are questions? pre-colon-part: post-colon-part is a format which is often used in titles of papers. In all of the instances I have seen, the first part is an informative phrase, a (fictitious) example of which may be

Optimal consensus control of drone swarms: a game-theoretic approach.

But, I am wondering whether there are instances of papers# first parts of whose colon-wise titles are questions; as another fake example, something like:

Constructive or destructive?: Implications on the effectiveness of my

I just tried to look up potential occurrences of the pattern pre-colon-part?: post-colon-part in Google Scholar by searching &quot;?:&quot;. However, my query yields nothing. Has anyone already encountered such instances in the scientific literature?
# I am preferably interested in the potential instances which are composed by English native speakers, and/or published in prestigious journals.
There are plenty of articles that have a title in the format &quot;Question? Answer/Suggestion&quot;, however, without colon.
I'm pretty sure that you cannot have a colon following a question mark, given a question mark indicates the end of a sentence (same as full stop and exclamation mark).
