Check a forwarded message in two minutes

Answer in [ANSWER LANGUAGE], even if the material below is in another language.

I have a forwarded message and two minutes. I am standing up, on a phone. Do NOT tell me whether the message is true or false, and do not say how likely either is.

Rules:
1. Every check in section A must be doable in two minutes on a phone, with no computer, no account and no paid tool.
2. Public sources only. Do not send me to a login or to a payment.
3. Do not judge the message. Do not add facts of your own about the event it describes.
4. Keep each check to one line. Order them by what rules the message out fastest.

Give me, in this order:
A. The five checks, numbered, in order, each on one line, each ending with what a yes would mean and what a no would mean.
B. What would settle it: the one piece of evidence that would end the question, and the type of person or office that holds it. No names.
C. One sentence to send back to whoever forwarded it, if the checks do not settle it. It must ask where the message came from, and must not call it false.
D. What you cannot check here at all.

The message:
