Problem: Given the question: You are given a new situation: Dan studied two islands. Loon island had a very stable environment, and there weren't many diverse species of plants and animals. Wolf island displayed lots of evidence for natural selection, and had a large variety of species inhabiting it. and a hint : New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. Please answer this question : Which island had more animals that survived their environment?
++++++++++++++++++++++++++++++++
The answer is:
Wolf

Problem: Given the question: You are given a new situation: Two students at the Agricultural Institute studied pedology. Bob studied soil weathering, while Dan studied types of soil. and a hint : Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. Please answer this question : Which student studied more about the top layers of soil?
++++++++++++++++++++++++++++++++
The answer is:
Bob

Problem: Given the question: You are given a new situation: Jeremiah and Alexander are students in a work shop class at their local community college. For their final project, they have to construct a compound machine to carry bricks across a room. Jeremiah's compound machine consists of many simple machines. Alexander's compound machine only consists of a few simple machines. and a hint : The mechanical advantage of a machine is the factor by which it changes the force applied to the machine. Many machines increase the force applied to them, and this is how they make work easier. Compound machines tend to have a greater mechanical advantage than simple machines. That's because the mechanical advantage of a compound machine equals the product of the mechanical advantages of all its component simple machines. The greater the number of simple machines it contains, the greater its mechanical advantage tends to be. Please answer this question : Which person's compound machine will have a larger mechanical advantage?
++++++++++++++++++++++++++++++++
The answer is:
Jeremiah's
