Take this simple sentence for example:
I like dogs and cats.
Which means I like dogs and I like cats. Simple.
What if I add an adjective "big" before the word "dogs"?:
I like big dogs and cats.
The first part is obvious, which means I like big dogs. What about the cat part though? Does it mean I like cats (size doesn't matter), or I like big cats? I have a feeling it's the former so if I want to say I like big cats, I would need to add the word "big" before "cats" but that sounds redundant to me.
Here is another example:
I want loud music and snacks.
This one is more obvious than the previous example since you can't apply "loud" to "snacks" since there is no such thing.
How do I know whether I need to apply adjective/adverb to consecutive nouns/verbs in a conjunction sentence respectively?
