As mentioned in the textbook, a 2005 Pew Research survey found that 51% of respondents favored "making it legal for doctors to give terminally ill patients the means to end their lives," but only 44% favored "making it legal for doctors to assist terminally ill patients in committing suicide". Anderson wants to show that his participants support euthanasia. Knowing the results of the Pew Research survey, he chooses to use the first phrasing in his survey to college students. As a result, Anderson's study is affected by:
A) Experimenter bias
B) Attrition
C) Motivated respondent bias
D) Social desirability bias

Question
