The correct answer is: He invented the two-cone rotary drill bit for easier oil-drilling in hard rock.
To determine the correct answer to the question, we need to understand the significance of Howard Hughes, Sr. in Texas history. Here are the options:
1. He invented the two-cone rotary drill bit for easier oil-drilling in hard rock.
2. He revolutionized the aviation industry by founding the Hughes Aircraft Company.
3. He was the father of Howard Hughes, Jr., and created the fortune his son inherited.

By analyzing the options, we can eliminate option 3 because although it highlights his connection to Howard Hughes, Jr., it does not address his importance in Texas history.
Options 2 and 4 can also be eliminated because there is no significant evidence suggesting that Howard Hughes, Sr. revolutionized either the aviation or farming industry.
This leaves us with option 1: "He invented the two-cone rotary drill bit for easier oil-drilling in hard rock." This option is correct because Howard Hughes, Sr. is known for his invention of the rotary drill bit, which greatly improved oil drilling techniques in Texas. This invention played a vital role in expanding the oil industry in the state and had a significant impact on Texas history.
Therefore, the correct answer is: "He invented the two-cone rotary drill bit for easier oil-drilling in hard rock."
