When did Peter last visit his parents?

The answer "January 2019" is correct because it provides a specific date, indicating precisely when Peter last visited his parents. This level of detail is critical during an interview as it demonstrates the ability to recall specific facts about personal history, which is often a requirement in immigration processes.

Having a specific date, such as January 2019, allows for a clearer understanding of the timeframe relevant to Peter’s situation. This could aid in establishing a timeline of his visits and maintaining transparency about his relationships, which can greatly influence the assessment of familial ties during the interview.

In contrast, the other options, such as “last month,” “two years ago,” and “in 2018,” do not provide the same clarity. These responses are more ambiguous and may lead to confusion, as they lack precise dates. This ambiguity can be less favorable during an interview as it raises questions about Peter’s attention to detail when discussing personal matters with immigration officials.
