Final answer:
The statement that people spend more time listening than engaging in other communicative behaviors is true, as is often seen with the usage of media. The claim about U.S. voting rates being higher than in Sweden and South Korea is false. Lastly, in physics, there are indeed two types of interference: constructive and destructive, which is true.
Step-by-step explanation:
The statement that most people spend more time listening than they do speaking, writing, or engaging in other communicative behaviors is true. In our contemporary society, it is common to be engaged with various forms of media that facilitate mostly one-way communication, such as watching television or using computers, where listening and consumption outweigh active speaking or writing.
The statement regarding voting rates being higher in the United States than in Sweden and South Korea is false. Generally, other established democracies tend to have higher voter turnout rates compared to the United States.
In the context of physics, the statement that there are two types of interference — constructive and destructive interference — is true. These phenomena describe the way in which waves can combine to either reinforce each other (constructive interference) or cancel each other out (destructive interference).
