Read the following excerpt from the pluto files by neil degrasse tyson.
the exhibit models, their accompanying text, and the
overall layout of the center organized the principal
contents of the solar system by objects of like properties,
rather than as enumerations of planets and their moons.
the formal tone is best maintained by which of the following paraphrases?

a. the typical museum layout was to organize celestial objects by
order, instead of the more logical grouping of common features.

b. the center was really great because everything was so organized
by what things were alike.

c. everything in the museum used to be all over the place, but then it
finally got fixed up into groups of the same things together.

d. there were planets and moons and such everywhere until they put
the parts together that were a lot like each other.
