Dentify the example of when situation and time are key to assessing risk of harm in a research study

Well if you ask a woman if she have had an abortion, that is an example of time and and situation being the key to assessing risk in a particular research study. This means that topics that are not controversial at one time and one place are not necessarily not controversial at other place or at some other point in time. Abortion is a good example as the risk is different in a country where that is normal and in another where it is not.
