This task is about using the specified sentence and converting the sentence to Resource Description Framework (RDF) triplets of the form (subject, predicate object). The RDF triplets generated must be such that the triplets accurately capture the structure and semantics of the input sentence. The input is a sentence and the output is a list of triplets of the form [subject, predicate, object] that capture the relationships present in the sentence. When a sentence has more than 1 RDF triplet possible, the output must contain all of them.

Example Input: The Phoenix on the riverside serves cheap fast food with a rating of 5 out of 5 by customers.
Example Output: [['The Phoenix', 'food', 'Fast food'], ['The Phoenix', 'priceRange', 'cheap'], ['The Phoenix', 'customer rating', '5 out of 5'], ['The Phoenix', 'area', 'riverside']]

Example Input: St. davids rfc had 2 wins and 1 draw.

Example Input: With 16 golds, Romania won second place.
Example Output:
[['2', 'TOTAL', '24'], ['24', 'GOLD', '16'], ['2', 'COUNTRY', 'Romania']]
