Problem: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Problem: 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: Why do the twin pillars of black rock seem ten or fifty miles away?
Options: (A) They were put so far away. (B) They lie across the Chihuahuan Desert. (C) It is difficult to judge the distance, with few milestones. (D) One lies in the Chisos Mountains, the other in the Sierra del Carmen.
Asnwer: C
Solution:
Yes
