Answer:
If I needed to write a compound subject or a compound predicate, the words I would use are:
and, or
Explanation:
A compound subject is a subject that has two or more elements. Let's compare:
- Sheila left her bag on the floor. (simple subject)
- Sheila and her brother left their bags on the floor. (compound subject)
In a compound subject, the elements can be joined by "and", "or", "nor", or even "both... and" or "neither... nor". That is why, among the options given in the question, the best one is the first: and, or.
Some more examples of sentences with compound subjects are:
- Stacy or Kim will show up to help, I am sure.
- Both Jason and his mother were born in Greece.
- Neither the cake nor the soup was any good.
The same goes for a compound predicate. In this case, we have two or more verbs sharing the same subject. The words and and or are also commonly used:
- I did my homework and cooked dinner.
