Pineda's maps are the earliest records of Texas history, but what is uncertain about his voyage?

• A. Whether he landed on Texas shores
• B. The year he mapped the coast
• C. His nationality
• D. The number of ships used

Answer: (A)

The main idea here is whether Pineda actually landed on the Texas coastline. His 1519 voyage produced the first known maps of Texas, showing the Gulf Coast and marking an important step in early Spanish exploration. What’s uncertain is whether he ever stepped ashore along the Texas coast or whether he only charted from ships at sea. The surviving evidence focuses on his coastal survey, but there isn’t clear, definitive documentation of a landfall on Texas soil, which is why this aspect remains uncertain. The other details—when he mapped the coast, his nationality, or the number of ships—are better established and don’t explain the lingering doubt about a landfall.
