I have a friend who will clim mount Kilimanjaro, a volcano in Tanzania
Oh wow! That would be quite the feat. I always admire people who do that.
Yes, It is the highest mountain in Africa
That's impressive. How tall is it?
The summit has been measured in 1999 and 2014, but I don't know the precise value. 
I bet it's huge. I wonder if a lot of people have climbed to it's peak.
It is a quite popular climb, while tough, Kilimanjaro is not as difficult as the Everest or K2.
