ead the following sentence.

The Earth is divided into a Northern and Southern hemisphere.

The underlined word contains the Greek affix hemi. The Greek affix hemi most nearly means ​
object.

This is incorrect. The Greek affix "hemi" does not mean "object." Instead, it means "half" or "part." In the given sentence, "hemi" is used in the word "hemisphere," which literally means "half-sphere."
