Step 1. The first gap follows 'By the time the rescue team reached...' and has the duration 'for three days'. The starvation began before the rescuers arrived, so the Past Perfect 'had been' is needed. Step 2. The second gap names the result of the arrival. The hikers do not perform the action; someone takes them to hospital, so the Past Simple Passive 'were taken' is required. Step 3. The pair 'have been / were taken' uses the Present Perfect, which cannot be linked to a past moment. The pair 'had been / took' makes the hikers the doers of the action, which is illogical. The pair 'were / had been taken' puts the taking before the arrival, which contradicts the sense. The correct pair is 'had been / were taken'.
