I have two questions:
in the following sentence: “Domestic suppliers in particular have been concerned that, since Agrokor owns some well-known food brands, they will lose shelf space in what is a key retailer for them.”
Is 'have been concerned' a Present Perfect Progressive Tense? Or is 'concerned' here used as an adjective and is it then the Present Perfect Simple Tense?
The same goes in the following case for 'have been connected': “The move is said to have been connected to his opposition of selling Laško’s stake in Mercator to Agrokor.”
The other problem I'm having is to make the grammar tree of the following sentence: “Former Economy Minister Andrej Vizjak says it is perfectly legitimate for Slovenia not to allow the merger between the two giants.”
In the Subject, which word is used as Headword, and what function has the 'not to allow ... two giants' part? Is it the DO of the dependent statement or is some sort of apposition (?) of the Subject of the dependent statement?
I would very much appreciate your help!!!
