Answer:
The natural resource that gave Texas a large economic boom was oil.
Step-by-step explanation:
In the early 1900s, the discovery of oil wells began an economic boom in the State. Today, its oil reserves are at 8 billion barrels (approximately one third of the total oil reserves in the United States) and its refining capacity is around 4.6 million barrels per day. It also produces a quarter of natural gas in the United States. Many oil companies are based in Houston.
