Verified step by step guidance

1. Step 1: Understand the key terms 'seldom happens' and 'sometimes happens' in the context of psychological research. These terms refer to the frequency or likelihood of an event occurring.
2. Step 2: Recognize that 'seldom happens' means the event occurs very rarely or infrequently, indicating a low probability of occurrence.
3. Step 3: Understand that 'sometimes happens' means the event occurs with moderate frequency, implying a higher probability than 'seldom' but not very often.
4. Step 4: Compare the frequency of occurrence between the two events: 'seldom happens' events are rare, while 'sometimes happens' events occur more regularly but not always.
5. Step 5: Conclude that the best description differentiates these events based on their frequency of occurrence, not on certainty or interpretation by researchers.
