Lhatoo was following us and caught up with (succeeded in reaching) us when we rested below the South Summit. After drinking some tea,’ we moved on. Lhatoo had brought a nylon rope so Ang Dorjee and I roped up while Lhatoo walked in the middle, holding the rope with one hand, more for balance than security.Lhatoo noticed that I had been climbing with oxygen at about two and a half litres per minute against the normal four for these heights. After he increased the oxygen flow on my regulator I found even the steeper stretches (distance) comparatively easy. (1) When did Lhatoo catch up with Bachendri and Ang Dorjee?(2) Why was Lhatoo holding the rope ?(3) At those heights what should be the normal amount of oxygen that one should breathe in?(4) Why did Lhatoo increase the flow of oxygen on Bachendri’s regulator?(5) What was the result of increase in the oxygen flow? |

Answer» (1) When Bachendri and Ang Dorjee were resting below the South Summit, Lhatoo caught up with them. (2) Lhatoo was holding the rope more for balance than security for Bachendri and Ang Dorjee. (3) At those heights the normal amount of oxygen that one should breathe in should be four litres per minute. (4) Lhatoo increased the flow of oxygen on Bachendri’s regulator because it was just two and a half litres per minute against the normal four for those heights. (5) As the result of increase in the oxygen flow, Bachendri found even the steeper stretches comparatively easy. |
