语法的时态啊!

题目

语法的时态啊!
I consulted with Wellness Center’s health educator whose name is Kevin about facts of sleep deprivation.
name后面的is应该用过去式吗？
and our topic was covered many aspects of sleep deprivation,such as what (is or was) the psychological consequences of Sleep deprivation?How (did or does) sleep deprivation affect a student’s daily life based on what you （knew or know) as an expert?
括号里用过去式还是一般现在时，什么是客观事实啊，客观事实一定要地球公转之类的吗？陈述一个人，或一件事，并且人或事永远不变是不是客观事实啊，纠结啊

答案

不该用过去式,如果用过去式意思变成这人以前叫这个名而他现在改名了.
用什么时态一切根据意思出发.
