Teacher: Given an input stream, the objective of this task is to classify whether words in the stream are grammatically correct or not. The input to this task is a stream of words, possibly from captions generated by a speech-to-text engine, and the output is a classification of each word from the labels (reason) = [NO_DIFF (correct), CASE_DIFF (case error), PUNCUATION_DIFF (punctuation error), CASE_AND_PUNCUATION_DIFF (both case and punctuation error), STEM_BASED_DIFF (stem word error), DIGIT_DIFF (digit error), INTRAWORD_PUNC_DIFF (intra-word punctuation error), and UNKNOWN_TYPE_DIFF (an error that does not corrrespond to the previous categories)].
Teacher: Now, understand the problem? If you are still confused, see the following example:
['hey', 'everybody', 'ivan', 'from', 'weights', 'and', 'biases', 'here', 'in', 'this', 'video', "i'd"]
Solution: ['CASE_DIFF', 'PUNCUATION_DIFF', 'CASE_DIFF', 'NO_DIFF', 'CASE_DIFF', 'UNKNOWN_TYPE_DIFF', 'CASE_DIFF', 'PUNCUATION_DIFF', 'CASE_DIFF', 'NO_DIFF', 'NO_DIFF', 'CASE_DIFF']
Reason: This sentence is a good example since the input stream is a grammatically incorrect statement and the output labels correctly classify the words that were incorrect.

Now, solve this instance: ['the', 'Mayan', 'civilization', 'is', 'one', 'of', 'the', 'most', 'long-lasting', 'civilizations', 'not', 'just', 'in', 'the', 'ancient', 'Americas', 'but', 'in', 'the', 'world', 'in', 'general', 'you', 'can', 'see', 'the', 'rough', 'outline', 'here', 'on', 'this', 'map', 'of', 'where', 'the', 'Mayan', 'civilization', 'occurred', 'you', 'can', 'see', 'it', 'has', 'the', 'Yucatan', 'Peninsula', 'in', 'the', 'north', 'the', 'Sierra', 'Madre', 'Mountains', 'in', 'the', 'south', 'and', 'it', 'covers', 'regions', 'of', 'modern-day', 'Southeast', 'Mexico', 'Guatemala', 'Belize', 'Western', 'Honduras', 'and', 'El', 'Salvador', 'we', 'believe', 'that', 'there', 'were', 'settlements', 'in', 'this', 'region', 'as', 'early', 'as', '2000', 'as', 'early', 'as', '2000', 'BCE', 'and', 'then', 'we', 'have', 'the', 'emergence', 'of', 'the', 'first', 'cities', 'around']
