There was an issue with the Spanish translation of the stem to this question. Statement III “La energia cinetica del electron” should have corresponded to the English “The kinetic energy of the electron increases”. This statement made up part of the correct answer (D), which refers to this statement and statement I. A manual adjustment was made to the marks for each candidate to ensure no candidate was disadvantaged for this question.

The paper has been amended for publication to the correct translation of “La energia cinetica del electron aumenta”.
