Question

circle the complete sentence. my favorite subject is reading. school we have lunch walking out.

Explanation:

A complete sentence has a subject and a predicate and makes sense on its own. "My favorite subject is reading" has a subject "My favorite subject" and a predicate "is reading" and is grammatically correct. "School we have lunch walking out" is a jumbled - up group of words with incorrect word order and no clear subject - predicate relationship.

Answer:

My favorite subject is reading.
