input: OPTIONS:
- disease
- mutation
- increased growth rate
- negative growth rate Now, answer this question: Answer the following question given this paragraph: In some countries, birth rates have fallen even lower than death rates. As result, their population growth rates are negative. In other words, the populations are shrinking in size. These populations have top-heavy population pyramids, like the one for Italy shown in Figure below . This is a new stage of the demographic transition, referred to as Stage 5. You might think that a negative growth rate would be a good thing. In fact, it may cause problems. For example, growth-dependent industries decline. Supporting the large aging population is also a burden for the shrinking younger population of workers. Q: What results when birth rates fall even lower than death rates? A:
A:
output: negative growth rate

Q: Answer the following question given this paragraph: True predation is when a predator kills and eats its prey. Some predators of this type, such as jaguars, kill large prey. They tear it apart and chew it before eating it. Others, like bottlenose dolphins or snakes, may eat their prey whole. In some cases, the prey dies in the mouth or the digestive system of the predator. Baleen whales, for example, eat millions of plankton at once. The prey is digested afterward. True predators may hunt actively for prey, or they may sit and wait for prey to get within striking distance. Certain traits enable organisms to be effective hunters. These include camouflage, speed, and heightened senses. These traits also enable certain prey to avoid predators. Q: When a predator kills and eats its prey, what sort of predation is this referred to as? A:
Answer: true

Problem:OPTIONS:
- magnetic force
- cooling force
- power force
- electric force

Answer the following question given this paragraph: When it comes to electric charges, opposites attract. In other words, positive and negative particles are attracted to each other. Like charges, on the other hand, repel each other, so two positive or two negative charges push apart from each other. The force of attraction or repulsion between charged particles is called electric force . It is illustrated in Figure below . The strength of electric force depends on the amount of electric charge and the distance between the charged particles. The larger the charge or the closer together the charges are, the greater is the electric force. Q: The force of attraction or repulsion between charged particles is called what? A:
****
A: electric force

Answer the following question given this paragraph: Metals are elements that can conduct electricity. They are one of three classes of elements (the other two classes are nonmetals and metalloids). Metals are by far the largest of the three classes. In fact, most elements are metals. All of the elements on the left side and in the middle of the periodic table, except for hydrogen, are metals. There are several different types of metals, including alkali metals in group 1 of the periodic table, alkaline Earth metals in group 2, and transition metals in groups 312. The majority of metals are transition metals. Q: The three classes of elements are metals, nonmetals, and what? A:
OPTIONS:
- ionic compounds
- molecules
- atoms
- metalloids
metalloids

Answer the following question given this paragraph: Mass can be destroyed to release energy. We do not ordinarily notice the increase or decrease in mass of an object because the change in mass is so small for a large increase in energy. The relativistic work-energy theorem is W net = E E 0 = mc 2 mc 2 = 1mc 2 . Relativistically,. Q: Mass can be destroyed to release what? A:
OPTIONS:
- acceleration
- mass
- velocity
- energy

Answer:
energy
