Question

select the common noun(s). the astronaut brings edna krabappels lucky penny everywhere.

Explanation:

To identify common nouns, we recall that common nouns are general names for people, places, things, or ideas (not specific names). In the sentence "The astronaut brings Edna Krabappel's lucky penny everywhere", "astronaut" is a general term for a profession, and "penny" is a general term for a type of coin. "Edna Krabappel" is a proper noun (specific name), so we exclude it.

Answer:

astronaut, penny
