Each short Latin sentence contains a time expression in English in parentheses.
Provide the correct Latin expression, giving the adjective first if there is one.
N.B.: dies (5th declension noun) has ablative singular die
and plural diebus,
and accusative singular diem and plural dies.
Examples: (For three hours) Quintus paterque ambulabant.
Answer: tres horas: accusative because it expresses how long, i.e. extent of time. (In the fourth hour) siluas uiderunt.
Answer: quarta hora: ablative because it expresses time when.
