Hint: One word is a verb and the other a noun. Use the traditional English language definitions. That's exactly what I mean. If I must explain something that simple, I'm afraid any explanation would also be, to you, ambiguous.
Sorry....you can't get away with that....what are OPERATIONS of a Port to YOU? Is that the Customs department? The Security Department? The loading and unloading? The Payroll Department? The hiring and firing? What kind of business experience do you have?.....there are MANY interpretations of "operations." Pick/describe the one/s you think are included in this agreement.
