The reason that they encouraged American interest in Texas explains the exploration of Zebulon Pike in Texas.
Pike was sent to the Mountains and the southern by General Wilkinson in 1806, but he was alerted not to gain entry into Spanish territory.
Pike discovered Pike's Peak in Colorado and attempted to climb it, but was unsuccessful. Pike continued south, crossing into Spanish territory, where he was apprehended and transported to Santa Fe (in what is now New Mexico).
Pike was one of the first people to visit New Mexico in the United States. The Spaniards set him free in Louisiana. The area he travelled through was mostly wasteland and unsuitable for farming, according to his travel notes.
For a time, this discouraged settlement in the area, but trade grew, and Pike's knowledge of the Spanish military's weaknesses proved invaluable.
Therefore, the correct option is the first sentence.
