When we choose meaningful distractors, changes we make are

  • small, and
  • concentrate in some carefully chosen parts of the text

$(x - y)^2 = x^2 + y^2 - 2 xy$

  • Change of type 1: vary where 2s are in the answer
  • That is, either in front of 𝑦2, 𝑧2 or in front of 𝑦𝑧
  • Changge of type 2: vary where the minuses are in the answer
  • That is, either in front of 𝑧2 or in front of 𝑦𝑧
