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

When it comes to black holes, matter really matters. After all, if it weren’t for all the matter crunched into a tiny space, an extreme gravity zone could never form. But it's not just how much matter in how small a space that makes a difference. How a star’s matter collapses also affects the black hole that forms.

Which fact is the author emphasizing in this excerpt?

A black hole is the same size as the star that it is created from.
When a black hole is created is just as important as how it is created.
How a black hole is created is just as important as how much matter it contains.
An extreme gravity zone creates black holes in spaces that are too tiny to imagine.

The fact that the author is emphasizing in this excerpt is:

How a black hole is created is just as important as how much matter it contains.

This is indicated by the statement that not only the amount of matter but also how it collapses affects the formation of the black hole.
