You will be given a definition of a task first, then some input of the task.
In this task you are given a sentence. You must judge whether the object of the main clause is singular(like: apple) or plural(like: apartments). Label the instances as "Singular" or "Plural" based on your judgment.

Even those most strenuously opposed to changes in the laws racked their brains in the hope that an escape clause would present itself.
Output:
Plural
