Final answer:
Close-ended questions have a definitive answer and can include options like true/false or multiple choice, whereas open-ended questions result in subjective responses.
Step-by-step explanation:
Questions that have a simple, definitive answer are called close-ended questions. This type of question often requires a simple response like "yes," "no," a specific piece of information, or a choice from limited preset options. They can be easily tested using scientific methods as their answers are objective and do not vary from person to person. In contrast, open-ended questions encourage a more elaborate response and result in subjective and varied answers. Open-ended questions are qualitative and provide a wealth of material, but they are harder to organize and tabulate.
