Question

the invertebrates haywardozoon pacificum and psychropotes dyscritus have recently been discovered inhabiting the clarion - clipperton zone (ccz), an area of abyssal plain between hawaii and mexico where mining is permitted. the number of other invertebrates that may inhabit the ccz is currently - as the areas bloom is poorly sampled and the few samples that have been taken cannot be presumed to be representative. which choice completes the text with the most logical and precise word or phrase? a infinitesimal b verifiable c tenuous d inestimable

Explanation:

The text states that the few samples taken cannot represent the area as it is poorly - sampled. So, the conclusion about the number of other invertebrates is not reliable. "Tenuous" means weak, flimsy, or not well - founded, which fits the context as the evidence is insufficient. "Verifiable" means able to be confirmed, which is not the case here. "Inestimable" means too great to calculate or value, which is not relevant. "Infiniformal" is not a standard English word.

Answer:

C. tenuous
