Problem: Tokyo recently had a large explosion in one of their largest steel manufacturing plants. The combination of heat, steel, and manufacturing materials released an extraordinary amount of carbon dioxide into the atmosphere. Meanwhile, Osaka has dramatically decreased the amount of carbon dioxide it releases through the installation of many public transportation projects and tree planting initiatives. Which city, Tokyo or Osaka, will contribute less to global warming? Hint: Pollutants also affect the atmosphere through their contribution to global warming. Global warming is an increase in the Earth's temperature. It is thought to be caused mostly by the increase of greenhouse gases like carbon dioxide. Greenhouse gases can be released by factories that burn fossil fuels. Over the past 20 years, burning fossil fuels has produced about three-quarters of the carbon dioxide from human activity. The rest of the carbon dioxide in the atmosphere is there because of deforestation, or cutting down trees ( Figure below ). Trees absorb carbon dioxide during cellular respiration, so when trees are cut down, they cannot remove carbon dioxide from the air.

A: Osaka

Problem: Given the question: Two bird islands experienced different levels of rainfall. West island experienced a lengthy drought that lasted several years. Many birds were affected by this drought. East island had several normal years as far as rainfall was concerned. Which island had more birds with smaller beaks that were better off? Hint: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection.

input question: Calving is sitting in his kitchen when he decides to play around with some ice and water. He takes an ice cube out of the freezer and puts it on a plate on his kitchen table. He then takes a glass of water and puts it into the freezer. He is curious to see if the ice cube will melt before the water freezes. Is the temperature of the ice cube's surroundings increasing or decreasing? Hint: In the study of thermochemical processes, things are viewed from the point of view of the system. A chemical reaction or physical change is endothermic if heat is absorbed by the system from the surroundings. In the course of an endothermic process, the system gains heat from the surroundings and so the temperature of the surroundings decreases. The quantity of heat for a process is represented by the letter . The sign of for an endothermic process is positive because the system is gaining heat. A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from the system, the temperature of the surroundings increases. The sign of for an exothermic process is negative because the system is losing heat.???
output answer: decreasing

Two brothers liked natural sciences. Ben decided to study Ecology, while his brother Dan decided to study Geography. They studied a lot and became very good at these subjects. Which brother studied more ecosystems? Hint: Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues.

Q: The two teams took different approaches in reinforcing the highway embankment slopes when building segments of the interstate. Team A led by Chuck relied almost entirely on inspiration and good building materials therefore decreasing slope stability, while team B lead by Mike used nature as an ally by planting tens of thousands of trees and shrubs to prevent slope failures and moderate soil transpiration and evaporation. Will the slope built by team B be stronger or weaker than the slope built by team A? Hint: The major effect of transpiration is the reduction of soil pore water pressures which counteracts the loss of strength which occurs through wetting, this is most readily seen as a loss of moisture around trees. However it is not easy to rely on tree and shrub roots to remove water from slopes and consequently help ensure slope stability. The ability to transpire in wet conditions is severely reduced and therefore any increase in soil strength previously gained in evaporation and transpiration will be lost or significantly reduced, consequently the effects of transpiration cannot be taken into account at these times. However it can be assumed that the chance of slope failure following saturation by storm event or periods of extended rainfall will be lessened as a result of transpiration. Moreover, although changes in moisture content will affect the undrained shear strength, the effective shear stress parameters as commonly used in routine slope stability analysis are not directly influenced by changing moisture content, although the water pressures (suctions) used in the analysis will change.[2][3]
A: stronger

[Q]: Two teams of agriculturists used different methods to improve production. Team Corn used organic methods, and team Plum used gibberellins for their crops. Which team didn't stop dormancy (resting time) of seeds? Hint: Gibberellins are hormones that cause the plant to grow. When gibberellins are applied to plants by scientists, the stems grow longer. Some gardeners or horticulture scientists add gibberellins to increase the growth of plants. Dwarf plants (small plants), on the other hand, have low levels of gibberellins ( Figure below ). Another function of gibberellins is to stop dormancy (resting time) of seeds and buds. Gibberellins signal that it's time for a seed to germinate (sprout) or for a bud to open.
