Level of measurement. Why would one not simply ask respondents to write down their age? That would offer much more precise information and would not cost them much effort either. Also, in this questionnaire, students measured at an ordinal level. It is preferable to measure at a ratio level.
Ambiguity. Someone who is 20, 30, 40 or 50 may have to think too long about what to do here. Also, you will never know what they decided in the end.
