Read this excerpt from A Black Hole is NOT a Hole.

You might want to tell the folks back home about this. Ah, well, too bad. Once across the event horizon, you wouldn’t be able to get out any blogs or vlogs, email or phone calls, snail mail, smoke signals, messages in bottles, or signal flares to spread the news.

Based on the topic of the excerpt, which question would be best for a reader to ask to check understanding?

Which other types of communication may I use?
Which folks back home should I tell about this journey?
Why would I not be able to send communication home?
Where does one cross over the event horizon?

The best question for a reader to ask to check understanding based on the excerpt is:

Why would I not be able to send communication home?

This question directly relates to the key point made in the excerpt about the inability to communicate once someone crosses the event horizon of a black hole.
