Question

It is difficult to treat chronic fatigue syndrome ---- it shares symptoms with many other conditions, such as depression and thyroid disorders, making an accurate diagnosis hard to reach.

Accepted Answer

because — Tedavinin zor olmasının sebebi, belirtilerin başka hastalıklarla örtüşmesidir; bu sebep ilişkisini 'because' kurar. 'Unless' olumsuz koşul, 'so that' ise amaç bildirir. 'Just as' benzerlik, 'as if' ise gerçek dışı bir benzetme kurar ve hiçbiri buradaki nedeni veremez.
