4. so much an illness or a physical condition, but it is a symptom of another problem, maybe a simple one like certain medications causing a reaction
5. so much an illness or a physical condition but symptomatic of another problem, maybe simply a reaction to certain medications

....is not so much ....是什么意思?

窃以为第一个题的were是虚拟语气 until (should) be .... if were

第二题是 “谈不上是“的意思
