I can't find the true and compatible match of the 'Trace' verb in these dictionaries?
Trace - Definition for English-Language Learners from Merriam-Webster's Learner's Dictionary
trace - Definition and pronunciation | Oxford Advanced American Dictionary at OxfordLearnersDictionaries.com
trace - Definition from Longman English Dictionary Online
None of them can't make sense to me.
Please give the correct meaning of sentence and match mentioned verb on dictionary.
Thanks a lot.
Definition #2 in your second link is:
trace something (back) (to something): to find the origin or cause of something
She could trace her family tree back to the 18th century.
The leak was eventually traced to a broken seal.
The police traced the call (= used special electronic equipment to find out who made the telephone call) to her ex-husband's number.
That seems to fit the bill, especially with the example sentence I have underlined.
In your sentence, the word before 'tons' should be 'carrie
