PART B: READ THE PASSAGE AND THEN CHOOSE FROM THE LIST A-G GIVEN BELOW THE BEST SENTENCE TO FILL IN EACH OF THE BLANKS. TWO OF THE SUGGESTED ANSWERS DO NOT FIT AT ALL. (5 PTS)
One of the strangest phenomena in the universe is the black hole. (1) . Like vacuum cleaners, black holes will suck up anything that crosses their path. The incredible sucking power that black holes generate comes from gravity. (2)
. Even light cannot escape the grasp of black holes. Since they are able to pull in light, black holes are nearly impossible to see even with high-powered telescopes. (3) . Black holes can originate in a few ways. (4) . They can also occur when the mass of a neutron star becomes so great that it collapses in on itself. (5) . These cosmic collisions unleash immense energy and can lead to the formation of massive black holes, further expanding our understanding of the universe’s complexity and diversity.
(A) They can quickly swallow up anything, including planets, space debris, and anything else imaginable
(B) One type of black hole occurs when a star comes to the end of its lifecycle and dies in a supernova explosion
(C) In the vast expanse of the universe, black holes remain as enigmatic cosmic entities, shrouded in mystery and intrigue
(D) However, scientists are able to detect the presence of black holes in space because of their effect on an observed area
(E) For years, scientists have studied black holes in an attempt to better understand how they function
(F) The first photograph of a black hole was captured by the Event Horizon Telescope in 2019, marking a significant achievement in astronomy
(G) Black holes may also occur when several large and dense stars collide with one another in space
