Cause-and-effect is a relationship where one event, the cause, leads to another event, the effect. For example, if it rains, the ground becomes wet. In this case, the rain is the cause, and the wet ground is the effect. Understanding this relationship helps us predict outcomes based on certain actions or events. In everyday life, cause-and-effect can be seen in various situations. If a person studies hard for a test, they are likely to achieve a good grade. Here, studying is the cause, and the good grade is the effect. Recognizing these connections can improve decision-making and problem-solving skills.
