Question

sort the words according to the meanings of their shared roots. extraordinary monologue monomania electrooculogram extracurricular oculist monocle ocular outside eye one; alone

Explanation:

The prefix "extra -" means outside, so "extraordinary" and "extracurricular" go in the "outside" category. The root "ocul -" relates to the eye, so "electrooculogram", "oculist", and "ocular" are in the "eye" category. The prefix "mono -" means one or alone, so "monologue", "monomania", and "monocle" are in the "one; alone" category.

Answer:

outside: extraordinary, extracurricular
eye: electrooculogram, oculist, ocular
one; alone: monologue, monomania, monocle
