SAT Reading & Writing: Logical Additions to a Paragraph

39+ practice questions in Praczo

What you need to know

The concept, explained

  • 1

    Questions asking you to ADD a sentence require diagnosing where the paragraph is going and what evidence is missing.

  • 2

    Read the sentence immediately BEFORE the proposed addition and the sentence immediately AFTER.

  • 3

    The new sentence must act as an unbroken bridge between those two thoughts.

  • 4

    Avoid additions that introduce entirely new topics not discussed elsewhere in the paragraph, even if they are factually true.

Common mistakes
  • Choosing an addition that summarizes an outside fact that feels relevant but disrupts the paragraph's chronological or logical flow.
  • Failing to notice that the addition uses a pronoun ("this discovery") that has no antecedent in the earlier sentences.
