Answer:
True
Step-by-step explanation:
The given statement asserts a true claim regarding the removal of prepositional phrases before checking the subject-verb agreement in a sentence. The key reason behind this is that prepositional phrases primarily function to add detail to the sentence but they also act as interruptions that come in between the subject and verb of the sentence and make it confusing for the reader. Thus, it is advised to remove them while examining the subject-verb agreement as the sentence would still convey a complete thought.
