When I read the first stimulus, my mind seems to focus on the notion of the past, including elements such as events that occurred in the past and people who existed in the past. Based on this, perhaps you could write a story about a character(s) who seeks closure in relation to either their past or someone else's (which would be important to the main character). You can introduce a significant event that occurred at some point in the past and pushed the main character(s) to embark on a journey to uncover truths and/or solve mysteries.
I interpret the second stimulus similarly to the first, although I do not sense an emphasis on the notion of the past like in the first stimulus. This can make it slightly more challenging to write a story, although it is definitely still possible. For example, you could write an imaginative piece that focuses on a main character being in a state of confusion when they are present in a particular place and/or are subject to particular circumstances. A potential ending would involve the character reaching a different (likely better) place and/or circumstances, allowing them to address said confusion.
Lastly, the third extract appears to emphasise the notion of uniqueness. As such, you could write an imaginative piece in which you explore an element such as a major discovery, and its resulting impact on the life of the main character(s).
I hope this helps!
