Can we draw the following hypothesis from the context (see options)? 

Context:

There is not a lot to see at the fort these days. The one remaining wall can be seen from the highway. There are a couple of historical markers that tell the story of the fort. And there is a picnic table and a couple of nice shade trees in the parking area.

Hypothesis: the fort was built yesterday
Possible answers: -- Yes. -- It's impossible to say. -- No.
