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: ["we're", 'in', 'the', 'British', 'Museum', '', 'looking', 'at', 'one', 'of', 'the', 'real', 'treasures', 'of', 'early', 'medieval', 'British', 'history', 'this', 'is', 'the', 'Sutton', 'Hoo', 'ship', 'burial', 'which', 'comes', 'from', 'East', 'Anglia', 'it', 'was', 'found', 'at', 'a', 'farm', 'in', 'the', '20th', 'century', 'he', 'was', '1938', 'that', '', 'series', 'of', 'mounds', 'were', 'excavated', 'there', 'was', 'a', 'series', 'of', 'burials', 'most', 'of', 'them', 'had', 'already', 'been', 'robbed', 'but', 'the', 'largest', 'one', 'they', 'found', 'a', 'ship', 'in', 'it', 'and', 'in', 'the', 'ship', 'was', 'treasure', 'and', 'we', 'think', 'originally', 'the', 'body', 'of', 'the', 'man', 'who', 'owned', 'this', 'material', 'he', 'would', 'have', 'lived', 'in', 'a', 'moment', 'when']
Student:
