It should be Independent --> (/TF or EB); therefore, (Independent and TF) --> EB. No independent store could sell TF and /EB.
You could conclude /TF--> EB if it said the stores sell one or both of TF and EB. You have to watch for instances where the diff between 'most' and 'some' is germane to the argument, but I don't think this is one of those times. A store could be in the minority and only sell lizards or whatever.
