Be given an opportunity to become as acerbic as (3,1,5)

'be given an opportunity' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'become as acerbic as' is the wordplay.
I cannot really understand how this works, but
'become' could be 'get' (synonyms) and 'get' is located in the answer.
'as' is present in the answer.
'acerbic' could be 'tart' (I've seen this in another clue) and 'tart' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'to' is the link.

Can you help me to learn more?
