[EX Q]: Background Paragraph: Population growth, especially in developing countries, should make people think about how fast they are consuming resources. Governments around the world should seriously consider these issues. Developing nations will also increase demands on natural resources as they build more factories ( Figure below ). Improvements in technology, conservation of resources, and controls in population growth could all help to decrease the demand on natural resources.
Story: A new country called Zandonia has recently found itself in a crisis. They are consuming far to many natural resources. A recent study concluded that the amount of resources being consumed greatly increased over the past 3 years. This find coincides with a population boom in the region. Before the population boom the demand for natural recources was relatively stable.
Question: Will Zandonia's population becoming even greater cause the demand for natural resources to increase or decrease?
[EX A]: decrease.

[EX Q]: Background Paragraph: Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4C.
Story: A waitress sets down two cups of water at a table and then takes the table's order. She leaves to place the order and the diners begin chatting and sipping on their water. Kim remarks that her water is room temperature and she wishes that it was cooler. Janet states that her water is so cold it hurts her teeth and wishes hers was warmer. They agree to mention it to the waitress when she returns.
Question: Which person's water has molecules moving faster?
[EX A]:
Kim.
