Give two examples of date$-$related queries $($i$.$e$.,$ automated computer checks to detect incorrect or illogical dates$)$ that could be caught in real$-$time during data entry or could be put into a nightly query report that is sent to study staff. $($For example, a query could look for dates of withdrawal that precede the date of informed consent; it doesn't make sense that someone could withdraw before they have even consented to participate!$)$
