Selecting 'Recognizable people or property?' option

[sueg12682656]

How do you choose when you say 'yes' to this when there is 'property' in your image?

I've checked the Contributor agreement which only refers to 'certain distinctive property' and I understand the restrictions on some specific places and buildings (eg. National Trust properties). But if I have an image of say a bridge over a canal - that is pretty obviously 'recognizable property' but I'm not sure (from seeing what is being sold on Adobe Stock) that this is what the intention is. There are plenty of photos of towns and villages available as commercial images (without logos, trademarks) but with property which is reconizable. 
Should I read 'Recognizable people or property?' to mean something more specific?

Those are recognisable properties and presumably there was a property release uploaded with other similar pictures.

I'm not convinced that people do get a property release for every house in a street, or for a bridge, or for a gate or a signpost - all will be in some way recognisable. Most manmade things outdoors are 'property' of someone, but I'm not sure a property release is needed for all of them - I'm just looking for a suggestion of where the line is drawn.
