Question

purpose for reading: while you are reading, pay attention to the intricate details about black holes and how they are portrayed as key components in our understanding of the universe. reflect on the connections between the different concepts presented, such as the formation, characteristics, and the broader implications of black holes in astrophysical research. ask yourself: \how does the author use specific examples and scientific facts to enhance our understanding of black holes and their significance in the universe?\
beyond the event horizon
(1) in the vast expanse of the cosmos, black holes stand as one of the most mysterious entities. these regions in space exhibit such intense gravitational forces that nothing, not even light, the fastest entity known in our universe, can escape their grasp once it crosses the event horizon. this boundary around a black hole represents the ultimate point of no return; anything that crosses it, whether a star, a planet, or a photon of light, is irrevocably drawn in, never to emerge again.
(2) the origins of black holes are deeply rooted in the life cycles of
according to paragraph 2, how do black holes form?
○ from the disintegration of comets
○ from the collision of multiple planets
○ by the accumulation of dark matter
○ from the collapse of massive stars after a supernova

Explanation:

To solve this, we recall scientific knowledge about black hole formation. Black holes typically form from the gravitational collapse of massive stars after a supernova explosion. The other options (disintegration of comets, collision of multiple planets, accumulation of dark matter) do not align with the established scientific understanding of black hole formation.

Answer:

From the collapse of massive stars after a supernova (the option with "From the collapse of massive stars after a supernova")
