Solution
The passage mainly discusses the structure and temperature of Earth's interior.
The word "mere" in line 2 is closest in meaning to "insignificant".
According to the first paragraph, most knowledge of Earth's interior has been gained by studying vibrations caused by earthquakes.
According to the second paragraph, the inner core and the outer core have greatly different temperatures.
The word "thoroughly" in line 15 is closest in meaning to "completely".
The word "it" in line 18 refers to the molten ball of rock.
The word "functioned" in line 18 is closest in meaning to "acted".
The word "manufactured" in line 20 is closest in meaning to "made".
The third paragraph mentions the decay of radioactive isotopes as one cause of the current high temperature of Earth's interior.
The term "seismic waves" is defined in the passage.
According to the passage, scientists do not understand in detail how the crust affects the Earth's internal temperature.
