In this task, based on a given sentence, we ask you to write a question that involves "transient vs. stationary" events, i.e., the understanding of whether an event will change over time (transient event) not (stationary event). For example, the sentence "he was born in the U.S." contains a stationary event since it will last forever; however, "he is hungry" contains a transient event since it will remain true for a short period of time. Don't create questions which have explicit mentions of answers in the text. Instead, it has to be implied from what is given. In other words, we want you to use "instinct" or "common sense". Note that the written questions are not required to have a single correct answer.
