Definition: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Input: Why does this happen?, Context: The storage in sensory memory and short-term memory generally has a strictly limited capacity and duration, which means that information is not retained indefinitely. By contrast, long-term memory can store much larger quantities of information for potentially unlimited duration (sometimes a whole life span). Its capacity is immeasurable. For example, given a random seven-digit number we may remember it for only a few seconds before forgetting, suggesting it was stored in our short-term memory. On the other hand, we can remember telephone numbers for many years through repetition; this information is said to be stored in long-term memory.
Output:
The storage in sensory memory and short-term memory generally has a strictly limited capacity and duration
