Are they both correct and have the same meaning?
- The cake eaten by Joe is delicious.
- The cake was eaten by Joe is delicious.
I found this sentence in learning past participle phrase.
The boy taken to hospital has recovered.
Taken to hospital is a past participle phrase. Why we don't add "was" before taken, I think the boy was taken to hospital. In a passive voice, it should add "was" to it.
