Answer
Brief Explanations:
Andrew Carnegie used vertical - integration. By combining his companies into one and controlling all aspects of steel production (from raw materials to distribution), he could eliminate competition and form a monopoly. Focusing on a single aspect doesn't lead to monopoly. Using profits for charity and increasing profits are not key to forming a monopoly.
Answer:
combining his companies into one company and controlling all aspect of steel production
