In this task, we ask you to write an implausible answer to a question that involves “event duration", based on a given sentence. Here, event duration is defined as the understanding of how long events typically last. For example, “brushing teeth”, usually takes a few minutes. Even though there exist multiple wrong answers, we only need a single wrong answer. Please try to keep your "answer" as simple as possible. Concise and simple "answer" is preferred over those complex and verbose ones.
One example: Sentence: Jack played basketball after school, after which he was very tired. 
Question: How long did Jack play basketball?
Solution is here: 22 hours.
Explanation: Typically we play basketball for a couple of hours. So any answer beyond that range is unlikely.

Now, solve this: Sentence: And so, by 600,000 b.c., about 50 km (31 miles) southwest of present-day Beijing, the ancestors of mankind were ready to settle down. 
Question: How long would it take them to walk to the location of present-day Beijing?
Solution:
1 months.
