You will be given a definition of a task first, then some input of the task.
You will be given a context and a verb separated with a newline character, and you have to answer if the given verb can be anchored in time or not. We say a verb can be anchored in the real timeline if and only if a verb happened in the past, is happening now, or is guaranteed to happen in the future. The output should be "Yes" if the verb can be anchored in time and "No" otherwise.

Once that happens, Gonzalez and Elian, though technically free to return to Cuba, should remain here to await an appellate court ruling on the case, which is expected next month.

 Verb: revoke
Output:
No
