Responding to Covid-19 — A Once-in-a-Century Pandemic?

[GoodTaste]

The use of question mark (?) is not clear to me. Is the grammatical sturcture of "Responding to Covid-19 — A Once-in-a-Century Pandemic?" "Responding to Covid-19 — Is It (Covid-19) a Once-in-a-Century Pandemic?" Because the question is whether Covid-19 is A Once-in-a-Century Pandemic, rather than our responding to it to be questioned.

Am I on the right track?

==========================

Responding to Covid-19 — A Once-in-a-Century Pandemic?

In any crisis, leaders have two equally important responsibilities: solve the immediate problem and keep it from happening again. The Covid-19 pandemic is a case in point. We need to save lives now while also improving the way we respond to outbreaks in general. The first point is more pressing, but the second has crucial long-term consequences.

Yes, the question mark makes the second clause a question.
