Part A Why did people believe it would be impossible to view a black hole in space?

Black holes absorb light.

They are hidden by other objects in space.

Black holes are too far away.

They are too dangerous to approach.
Question 2
Part B

Which two sentences from the text best support the answer in Part A?

"Black holes can even pull light into themselves."

"Messier 87 is about 55 million light years from Earth."

"Since we need light to see, we cannot see black holes."

"A galaxy is a system of millions or billions of stars."

This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe. Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.

multiple settings

< > reasoning \ evidence < >

novels have multiple settings. a setting is a place or surrounding when a main event or event takes place. not everything happens in just one scene or setting. yes, there can be one *main* setting, but there is definitely not just one. b is incorrect. novels do not have limited characters. there are many characters in a novel, depending on how many the writer wishes to add in. c is incorrect. there is not just a single theme. there are many themes. another word for "theme" is the subject. there can be many subjects and topics. once again, there are many, depending on however many the author wishes to add or include. d is incorrect. yes, novels *can* have no solutions, based on what the author would like. but typically, novels have a solution. the solution might be in "book 5", but there is normally still a solution.
