Answer: similar names
Explanation: they have similar name but are still different and thats why their perspectives are different.
Pre- is prefix that means before or previous to, therefore "precooked" means it is already cooked.
I’m not sure what the question is. “Come” would be the correct present tense for the sentence, but if you need a different word with the same meaning to replace it with, then you can use “arrive” instead.
I hope this helped, if not, then you can reply specifying what the question is.
