Final answer:
The noun rīsū (line 7) is not in the same case as the others: victōria, Scīpiō, and dubiō, which all belong to the ablative case in Latin.
Step-by-step explanation:
The noun victōria (line 4), Scīpiō (line 5), and dubiō (line 6) all belong to the ablative case. The noun rīsū (line 7) does not belong to the same case as the others. The ablative case is used to indicate various meanings such as by, with, from, in, or at. In this context, victōria, Scīpiō, and dubiō are all used as ablative case nouns to show different relationships within the sentence. On the other hand, '-ō' can indicate either the nominative singular case for second declension nouns, or the ablative singular for both first and second declension nouns, which may apply to 'Scīpiō'. The endings '-ō' and '-ū' are typically ablative singular endings, which would apply to 'dubiō' and 'rīsū' respectively. Here, it's likely that 'Scīpiō' is in the same case as 'victōria', while 'dubiō' and 'rīsū' are in the ablative case.
