Q: Read the following article and select the best answer. Article: Crossing Texas and Mexico, the Big Bend region is high in biodiversity . It's a place so _ that if something doesn't bite, stick, or sting, it's probably a rock. You know you have arrived in the heart of the Chihuahuan Desert when it feels as if you have fallen off the edge of the earth and into the rabbit hole. Nothing is as it appears. Moths are the size of birds. Are those twin pillars of black rock (a landmark known as Mule Ear Peaks) ten miles (16 kilometers) away or fifty (80 kilometers)? Visibility reaches more than a hundred miles on a clear day, and since there are few roads or buildings to use as milestones, distance is difficult to judge. This is a place where water runs uphill, where rainbows have to wait for rain. The line between myth and reality is unclear. Stare long enough at the Chisos Mountains or the Sierra del Carmen, the two mountain ranges, known as sky islands, which lie on the land, and they rise and float above the plain. The vast Chihuahuan Desert is a land of no people. There is always the chance you'll die of thirst. The "You Can Die"possibilities are endless, and keep some visitors -- 350,000 a year to Big Bend National Park, built in 1944 -- from coming back. Those who do return are left to think of the remarkable courage of the brave few who have managed to survive in this terrible environment. Question: How many years are there since the Big Bend National Park was built? - 350,000 years. - 350 years. - 66 years. - 44 years.
A: 66 years.
