Problem: Article: Homework can put you in a bad mood , 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: Just when scientists think they have discovered and recorded every species of insect that crawls on the earth they find something new.Earlier this month, Peter Jager, the head of Frankfurt's Senckenberg Research Institute reported the discovery of a unique eyeless spider! The creature that has a leg span of six centimeters and a body size of just twelve millimeters was found in a cave inside the tiny nation of Laos, in Southeast Asia. It was identified as a member of the Huntsman spider, a large family that consists of 1100 species.However, the other members of the family all have eyes.The spider is the first one that has no eyes.The scientists believe that the reason for the lack of eyes can be that these spiders spend their entire life inside caves.In the past they have seen other members of the Huntsman spiders living in caves with six or less eyes.They believe that the kind of spider has adapted to the fact that they do not really need the eyes to such an extreme measure that they have _ them altogether. But they are not the only creature to have done that.Over the years, scientists have discovered completely blind cave fish, and even a freshwater crab, which happens to live in the same cave as this eyeless spider! Surrounded by Burma and China on the northwest, Vietnam on the east, Cambodia on the South and Thailand on the west, the landlocked nation of Laos has been a treasure trove of an incredible number of new and exotic species.In the last few years researchers have discovered the Saola -- never-before seen antelope-like creature, a small deer species called muntjacs, a tiny striped rabbit and a rock rat that was thought to have been extinct 11 million years ago.In addition to that it is also home to over one hundred species of large mammals ranging from tigers to macaques and over 165 species of amphibians and reptiles like the terrible King cobra and the noisy Tokay gecko, a permanent resident inside most Laos households.
Question: What can we know about the newly discovered species of spider?
Options: (A) They are smaller in size. (B) They only live in Laos. (C) They belong to the Huntsman spider. (D) About 1100 such spiders were discovered.
Solution:
C
