What significant action do Rockefeller's new competitors take that angers him?

• A. They raise oil prices
• B. They plan to build their own oil pipeline
• C. They block his shipments
• D. They refuse to partner with him

Answer: (B)

Rockefeller's new competitors anger him primarily by planning to build their own oil pipeline. This action directly threatens his monopoly over the oil transportation infrastructure, which he had worked diligently to establish. The pipeline was crucial for moving oil from refineries to markets, and by creating an alternative, his competitors were encroaching on his field of dominance. This move not only signaled their intent to challenge his authority but also potentially undermined his control over oil prices and distribution—a central aspect of his business strategy. Such competitive actions were seen as a direct threat to his carefully constructed empire, prompting his anger and leading him to take aggressive measures to maintain his market position.
