heat, either in water or in saturated soil, was likely involved in the formation of thecircles.

In attempts to explain how they were formed, two hypotheses are currently most commonly debated: one proposes frost, the other heat.

frost cannot be the complete explanation for the uniformity in size of the circles on Marion Island, located in the maritimeSubantarctic.


One aspect of the argument that we may notice is that it says basically the following. Since one thing, "frost," cannot explain the uniformity in size of the circles, another thing, "heat," was likely involved.

So, the conclusion that heat was likely involved is based only the fact that frost alone could not have produced the circles. The argument does not include any direct evidence that heat was involved.

The correct answer will weaken the support for the conclusion or cast doubt on theconclusion.
