Legatus ad senatum venit ut auxilium peteret.
The verb peteret is in the subjunctive mood to express...
- the result of the legate's arrival.
- the time at which the legate arrived.
- the purpose of the legate's arrival. (correct answer)
- a condition upon which the legate arrived.
Explanation: The clause ut auxilium peteret is a purpose clause, introduced by ut and containing a subjunctive verb. It answers the question "Why did the legate come?" ("in order to seek aid"). Distractor A confuses a purpose clause with a result clause. Distractor B refers to a temporal clause (e.g., using cum or ubi). Distractor D refers to a conditional clause (using si).
