Ludwig's WRAP-UP
In summary, "what sure does" is a versatile English phrase most frequently employed in high-quality journalism and academic discourse.

While it often appears within the negative construction "not sure what...", its use as an intensifier is a valid way to add weight to a statement. Writers should be careful not to confuse it with the interrogative word order in indirect questions, but otherwise, it remains a reliable tool for expressing varying degrees of certainty and functional description across different registers.
