This sentence tests parallel structures. The 2 facts about the microbes must be parallel: "Places...tend to be populated by microbes that seem to flourish and that are called extremophiles"

Hi kobel51,

A quick scan of the answer choices choices shows that all 5 use the word "AND" which means that we'll need to focus on 2-part parallelism to answer this SC.

The concept behind parallelism is that both sentence fragments will need to have the same "format": the same order and type of words.

The correct answer C is the only answer that presents proper parallel format: "that" + verb/description.
