How have the jury in a personal injury trial been advised not to accept or deny evidence of a letter containing prejudicial information?

We must presume that the jury followed the instructions. (People v. Montes (2014) 58 Cal.4th 809, 888.) The prosecutor did not repeat the question, no evidence of the letter was admitted and the prosecutor did not mention the letter in closing argument. This brief mention of the letter did not result in the admission of such prejudicial information that the results of the trial would have been different had the question not been asked.
