Question

1. which of these is a complete sentence?

my best friend, ezra.
sarai swam in the pool.
before you catch a cold.
went to the park after school.

Explanation:

A complete sentence needs a subject and a predicate (a verb and a complete thought).

• "My best friend, Kara." is a noun phrase, no verb or complete thought.
• "Sarai swam in the pool." has a subject (Sarai), a verb (swam), and a complete thought (what Sarai did).
• "Before you catch a cold." is a dependent clause, no independent clause structure.
• "Went to the park after school." has a verb but no subject (who went?).

Answer:

B. Sarai swam in the pool.
