Final answer:
Option 4, 'mondays poss-my friend ix-they(singular) volunteer where_rhq soup kitchen', is the correct gloss for the sentence 'my friend volunteers on Mondays at the soup kitchen' as it accurately relays the details of the original sentence in ASL gloss notation.
Step-by-step explanation:
For glossing ASL (American Sign Language), the correct gloss for the sentence "my friend volunteers on Mondays at the soup kitchen" appears to be option 4:
mondays poss-my friend ix-they(singular) volunteer where_rhq soup kitchen
This gloss indicates that the friend volunteers at a specific location (the soup kitchen) and does so on Mondays, which is consistent with the structure and meaning of the original English sentence. Note that the abbreviations used in the gloss denote the following: 'poss' for possessive, 'ix' for indexing or pointing out a referent in ASL, 'they(singular)' for singular third-person pronoun, and 'where_rhq' which is a rhetorical question used in ASL to indicate location.
