I need your help. I'm in a new city and I need to find the nearest grocery store. I asked a local and they said: Beneden aan de weg is een grote kruising. Ga dan linksaf bij het kanaal. Deze oude kerk moet aan de rechterkant liggen, tegenover de markt. De supermarkt ligt er direct achter. What is next to the grocery store? Return the result as your last paragraph, like this: LOCATION: [answer]

Let me translate the directions from Dutch: - **Beneden aan de weg is een grote kruising** = "At the bottom of the road there's a big intersection." - **Ga dan linksaf bij het kanaal** = "Then turn left at the canal." - **Deze oude kerk moet aan de rechterkant liggen, tegenover de markt** = "This old church should be on the right side, across from the market." - **De supermarkt ligt er direct achter** = "The supermarket is directly behind it." So after turning left at the canal, you'll see an old church on your right (which sits opposite the market). The supermarket is located directly behind that church — meaning the church is the landmark right next to the grocery store. LOCATION: The old church (which is across from the market)
