Question

Read this paragraph: The exhibit models, their accompanying text, and the overall layout of the Rose Center organized the principal contents of the solar system by objects of like properties, rather than as enumerations of planets and their moons. This decision landed Pluto among the growing number of icy objects found beyond Neptune, and left it unmentioned and out of view among our models for the rocky, terrestrial objects (Mercury, Venus, Earth, and Mars) and the gas giants (Jupiter, Saturn, Uranus, and Neptune). By this organization, we practically abandoned the concept of planet altogether. Neil deGrasse Tyson, The Pluto Files What is the main idea of this paragraph?
A.The exhibit at the Hayden Planetarium didn't classify Pluto the same way it classified other planets.
B. Pluto was considered just another icy object that was found in abundance in the solar system.
C. Mercury, Venus, Earth, and Mars are considered rocky, terrestrial objects instead of planets.
D. Jupiter, Saturn, Uranus, and Neptune are filled with gas and are therefore considered gas giants.

Answer 1

B. Pluto was considered just another icy object that was found in abundance in the solar system.

deGrasse Tyson, in this paragraph, describes how the Rose Center classified planets, especially Pluto. It states that it was counted as just an icy object instead of putting it as one of the rocky, terrestrial objects or as one of the gas giants.
