   whether the traditional techniques for building reed boats were in use at the time

   Why this is right

   If the traditional techniques the experimenters used to build their reed boats weren't in use at the time Tiwanaku would have been building their reed boats, then the evidence the experimenters have offered is total garbage. They made a boat using techniques that didn't exist with the Tiwanaku and carried much lighter stones ... that does not show that it's possible the Tiwanaku carried 40 ton stones with their style of reed boats.

   whether green andacite stones quarried at the time Tiwanaku was inhabited were used at any

   Whether these big stones were also used near the quarry or not used near the quarry doesn't illuminate anything about whether the Tiwanaku were able to move 40 ton stones across a lake on reed boats.

   whether the green andacite stones at Tiwanaku are the largest stones

   Whether the 40 ton stones were the largest stones or the 2nd largest or 3rd largest doesn't tell us anything about whether the prehistoric Tiwanaku people were able to move 40 ton stones across a lake on reed boats.

   whether the reed boat built for the experimenters is durable enough to remain usable

   This is the most tempting trap answer, but whether the reed boats built by the experimenters are now usable for several years or whether they only last one year doesn't really affect the plausibility of the hypothesis. There was nothing in the prehistoric storyline that required that the reed boats the Tiwanaku built would last for several years, only that they were capable of a one-time move of 40 ton stones across a lake.
