[Q]: Dan is a dance instructor. In an upcoming dance competition he has to send two groups of students, group A and group B. He dressed group A students with godet. But he didn't dress group B students with godet. There are two categories of dance, category C and category D, in the dance competition. Category C requires lots of motion, but category D does not required much motion. Dan has to decide which of his student groups would compete in category C and which group to compete in category D. Would group A be suitable or unsuitable for category C competition? Hint: A godet (/ode/ or /odt/)[1] is an extra piece of fabric in the shape of a circular sector which is set into a garment, usually a dress or skirt.[2] The addition of a godet causes the article of clothing in question to flare, thus adding width and volume.[3] Adding a godet to a piece of clothing also gives the wearer a wider range of motion.[4]

[Q]: Two countries were neighbors, separated by a mountain range. Ghana used fossil fuels to produce energy, but one of the consequences of that was increased air pollution and acid rain. Brunei was a country inhabited by nature lovers and tree huggers, so they were very protective of their environment. Which country had larger amounts of low pH precipitation in the forests? Hint: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust.

[Q]: Two pedologists studied different types of soil. Yun studied forest soils, while Jian studied grassland soil. They were both very surprised with they findings. Which scientist read less about grassland fires? Hint: In grassland, much of the organic matter added to the soil is from the deep, fibrous, grass root systems. By contrast, tree leaves falling on the forest floor are the principal source of soil organic matter in the forest. Another difference is the frequent occurrence in the grasslands of fires that destroy large amounts of aboveground material but stimulate even greater contributions from roots. Also, the much greater acidity under any forests inhibits the action of certain soil organisms that otherwise would mix much of the surface litter into the mineral soil. As a result, the soils under grasslands generally develop a thicker A horizon with a deeper distribution of organic matter than in comparable soils under forests, which characteristically store most of their organic matter in the forest floor (O horizon) and thin A horizon.

[Q]: Most surfers used Wide beach because of the areas of shallow water, but some surfers were happy with Sandy beach, although the water was much deeper at the shore there. Which beach experiences a higher and steeper swell? Hint: When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape. After the wave breaks, it becomes a wave of translation and erosion of the ocean bottom intensifies.
