Jane ... her new passport last month.

Grammar Rule: Simple Past vs. Present Perfect

We use the Simple Past tense to talk about actions that happened at a specific time in the past. The phrase 'last month' indicates a specific time in the past.

The structure of Simple Past with the verb 'get' is 'got'.

The structure of Present Perfect is 'has/have gotten'. This tense is used for actions that happened at an unspecified time in the past or have relevance to the present. Since 'last month' is a specific time, Simple Past is appropriate here.

Let's analyze the options:

• got: This is the Simple Past tense of 'get'. It fits the context of a completed action at a specific time ('last month').
• has gotten: This is the Present Perfect tense. It's less appropriate here because 'last month' specifies the time.
• gotten: This is the past participle of 'get' used in the Present Perfect (e.g., 'has gotten') or Past Perfect (e.g., 'had gotten'). It cannot stand alone with 'Jane' in this sentence structure.
• get: This is the base form or Present Simple tense. It does not fit the past context.

Therefore, the correct option is 'got'.
