Question

an adverb
a conjunction
an interjection
a pronoun
which sentence contains a gerund? *
the broken vase lay on the floor.
swimming is her favorite exercise.
she will travel to europe next summer.
they have completed the project early

Explanation:

First Question:

• An adverb modifies a verb, adjective, or other adverb. "Wow" does not modify, so not an adverb.
• A conjunction connects words/phrases/clauses. "Wow" does not connect, so not a conjunction.
• An interjection is a word expressing emotion/feeling (like surprise, excitement). "Wow" shows excitement, so it is an interjection.
• A pronoun replaces a noun. "Wow" does not replace a noun, so not a pronoun.

• A gerund is a verb form ending in -ing that functions as a noun.
• In "The broken vase lay on the floor", "broken" is an adjective, no gerund.
• In "Swimming is her favorite exercise", "Swimming" (verb + ing) acts as the subject (a noun), so it is a gerund.
• In "She will travel to Europe next summer", "travel" is a verb, no gerund.
• In "They have completed the project early", "completed" is a verb (past participle), no gerund.

Answer:

C. an interjection (assuming the option labels are A, B, C, D with C being "an interjection")
