Show Answer Key & Explanations Step-by-step solution for: Compound Subject, Compound Predicate, and Compound Sentence Bundle
Let’s go through each sentence one by one. We’re looking for the compound subject — that means two or more subjects joined by “and” or “or” that share the same verb (predicate).

We’ll underline the compound subject in each sentence.

---

1. Ashley and Bill have been married for 10 years.
→ Who is doing the action? Ashley and Bill → both are subjects, joined by “and”.
Compound subject: Ashley and Bill

2. Mrs. Rice or her husband will attend the parent conference.
→ Two people connected by “or” — either Mrs. Rice OR her husband. Still a compound subject.
Compound subject: Mrs. Rice or her husband

3. Cats and dogs fight like crazy.
→ Cats + dogs = two subjects joined by “and”.
Compound subject: Cats and dogs

4. T-shirts and jeans are my favorite things to wear.
→ T-shirts + jeans = two things, joined by “and”.
Compound subject: T-shirts and jeans

5. Peyton and Preston are four years apart in age.
→ Peyton + Preston = two names, joined by “and”.
Compound subject: Peyton and Preston

6. Cookies and cupcakes are his favorite desserts.
→ Cookies + cupcakes = two foods, joined by “and”.
Compound subject: Cookies and cupcakes

7. Bobcats and cheetahs run at the same speed.
→ Bobcats + cheetahs = two animals, joined by “and”.
Compound subject: Bobcats and cheetahs

8. Nine or one and number five are his best questions.
Wait — this one looks tricky. Let’s read it again:
“Nine or one and number five” — actually, this might be poorly written, but we can still find the compound subject.
It seems like there are three items: Nine, one, and number five — connected with “or” and “and”. But since they all share the same verb “are”, they form a compound subject together.
Actually, let’s break it down:
The phrase is “Nine or one and number five” — grammatically, this could mean (“Nine or one”) and “number five” — so two parts joined by “and”.
But even if it’s messy, the whole thing before “are” is the subject. So:
Compound subject: Nine or one and number five

*(Note: This sentence is awkwardly written, but based on structure, we take everything before the verb as the subject.)*

9. Peanut butter and jelly tastes wonderful together.
→ Peanut butter + jelly = two things, joined by “and”. Even though the verb is singular (“tastes”), it’s still a compound subject treated as one unit.
Compound subject: Peanut butter and jelly

10. Letters and numbers are learned in preschool.
→ Letters + numbers = two things, joined by “and”.
Compound subject: Letters and numbers

1. Ashley and Bill
