10 years ago/later, which is 2010, the Avengers fought/ fights the villian Thanos.
who else wants the burger? why else would he do that?
Why are the adverbs later, ago, and else placed after 10 years, who and why?
i think 10 years is a noun phrase modified by 'ago', the adverb and because you can modify it with an adjective clause, 'which is 2010' from the sentence.
The same goes to the other sentence. Why is the adverb placed after the word it is modifying?
What does the rules say or is this just how we use it?
