The English sentence is unnatural. A better sentence would be "Is a large amount of capital needed to develop tourism here?"
No one says Is a large capital, its just Is large capital
If you were to add amount then you would like the word jumlah
Stupid app cant edit post
Agreed, 'a large capital' makes me think of 'a large capital city.'
Additionally, I believe "diperlukan" would be a better verb form for the Indonesian...?
