Show answer & explanation
Correct answer: D
CONCEPT
A one-word substitution replaces a descriptive phrase with a noun that preserves the phrase’s exact meaning and grammatical role.
Word parts can help: the prefix hemi- means “half”, and sphere names a completely round three-dimensional solid.
APPLICATION
The quoted phrase describes one of the two equal halves of a sphere. Combining hemi- with sphere gives hemisphere, the noun for either such half.
CONTRAST
A globe is a spherical object or model, especially a representation of Earth.
A cylinder has two parallel circular bases joined by a curved surface.
A sphere is the complete round solid rather than one of its halves.
RESULT
The best replacement is “a hemisphere”.
