<h3>Answer:</h3>
c. Using a combination of policy tools prevents the use of mandatory policies.
<h3>Explanation:</h3>
Regulating and controlling behavior is crucial for authorities. Authorities employ a number of tools such as enactment, penalties, laws, taxes, and support in order to change behavior in the concern of the people. The rising amount of policy difficulties has produced a difficulty for governments to control action. Moreover, conventional tools and methods in executing policy may be insufficient and ineffectual in circumstances of our current situation.
The correct answer is C. Here's why:
Choice A is illogical. A single experiment does not confirm a theory as true. Multiple successful trials are needed for one to even consider a hypothesis to be accepted as a theory.
Choice B is wrong. If a scientist finds a new way to test a hypothesis, experimental methods do change. Note that when there are additional ways to test a hypothesis, a scientist should test it with additional methods.
Choice D is incorrect. If someone finds a way to test a new hypothesis, it would not be made into law since there is more information regarding the theory. This means that it would remain a theory until one can prove that it can't be tested using different methods.
Whales are closely related to hoofed mammals with an even number of toes, such as horse, because they evolved from them. Before whales were what we know them as today, they were relatively similar to horses. They used the water to flee from predators, and they evolved slowly to heighten their swimming ability, eventually becoming modern day whales. Fish have always been aquatic animals that have gills. Whales cannot breathe underwater, so they take in oxygen the same way a horse does. Also, both horses and whales are mammals that give birth to their offspring and are warm-blooded. Fish lay eggs and are cold-blooded.
