Mastering Boundaries Questions on the Digital SAT


A step-by-step guide on how to tackle these Standard English Convention questions.



The “Boundaries” question on the digital SAT is designed to evaluate students' grasp on standard English grammar, particularly sentence formulation, utilization, and punctuation.

Boundaries questions explore the message conveyed within a passage as well as the manner in which it is articulated. They underscore the need for sentences to be structurally sound and complete, adhering to the conventions of Standard English Conventions.

The questions are always phrased as "Which choice completes the text so that it conforms to the conventions of Standard English?", but be aware that they are not the only question type using this formatting: Form, Structure, and Sense questions also use the same wording but test subject-verb conjugations instead.


Example Question:


Leonardo da Vinci, primarily celebrated for his masterpieces like the Mona Lisa, was not just a painter but also a dedicated scientist that enjoyed the study of ________ him to create detailed sketches of the human body, and proposing early concepts of the human biology.

Which choice completes the text so that it conforms to the conventions of Standard English?


The appropriate punctuation ensures that the relationship between Leonardo da Vinci's interest in anatomy and the consequent works inspired by that interest is clear and easily understood.
