[Q]: Article: There are some things humans can go without. We can lose a kidney or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can _ without stomachs. One such fish is the stout longtom. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost. The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. It teeth are not good at cutting fish into pieces, so it swallows fish whole. Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish. Day's results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin that can break down proteins without acid -- although the approach is less efficient than using a stomach. Because it's a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein. Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is "a fairly expensive organ to run". This perhaps explains why some animals have got rid of theirs.
Answer: digests the smaller fish in its body
[A]: Ryan Day ran the chemical tests in order to find out how the longtom _ .

[Q]: Article: In all the world's cultures, people sing, play instruments, and celebrate with music. It plays such an important role in our lives that all fields focus on its study, including one looking at the biology of music. Experts are finding that because of the way our brains process music, learning to play an instrument or just listening to music can have a wide range of benefits. Music education has received a lot of attention. Learning to play an instrument can help children improve math, science, and language skills. One study in Canada tracked children's IQ scores for nine months, discovering that children who studied music had the biggest test score improvements. The secret may lie in the way reading music and playing notes uses several areas of the brain, increasing our ability to learn school subjects. For example, reading notes improves spatial reasoning skills, which are helpful in solving math problems like fractions . Music is also used for medical purposes, such as the treatment of diseases which affect memory. The secret lies in the way the brain processes music. One area near the forehead, the medial prefrontal cortex, connects music with memories stored in two other areas: the amygdale and hippocampus. That's why an old song can remind you of something that happened years ago. For patients suffering from diseases like Alzheimer's, listening to music can help unlock buried memories by strengthening musical pathways to memories. With the evidence of music's benefits pouring in, it's no wonder some countries make music study a part of their education systems. People are recognizing that more than just a form of entertainment, music is also great for the brain.
