Come up with a question and stream of consciousness reasoning that would justify this answer: it is not possible to tell
The question is: Given the sentence "One of the buses is marked ""linea express"" while the other is marked ""metropolitan transit system"". ." can we conclude that "The buses are fast."?
Options:
- yes
- it is not possible to tell
- no
Stream of consciousness: The markings on the buses do not imply that the buses are fast.
