Take the following as truth: Across the river Authie and a few minutes' drive east is the 18th-century Abbaye de Valloires, whose huge gardens display more than 5,000 species and varieties of plants, many from China and Japan, including a large collection of old-fashioned and wild rose, presented in a number of formal and informal settings.
Then the following statement: "The Abbaye de Valloires is to the north-west of the river Authie." is true, false, or inconclusive?
Answer: False
