Could you guys please explain about these sentences?
- One such proposal is FOR the vertical farm.
- The concept is OF multi-storey buildings
I can't understand about FOR and OF in these sentences.
'Many believe an entirely new approach to indoor farming is required, employing cutting-edge technologies. One such proposal is FOR the ‘Vertical Farm’. The concept is OF multi-storey buildings in which food crops are grown in environmentally controlled conditions.'
Can 'consist of' be used as the same meaning as 'be of' in this context? Are there any other words or terms to replace these words in this instance?
