It is likely that only one type of bacteria hibernates regularly. If bacteria are extremely diverse, it is unlikely that most types of bacteria hibernate regularly. Bacteria of most types are usually in hibernation. It is probably not true that most types of bacteria hibernate regularly.
Scientists studying a common type of bacteria have discovered that most bacteria of that type are in hibernation at any given time. Some microbiologists have concluded from this that bacteria in general are usually in hibernation. This conclusion would be reasonable if all types of bacteria were rather similar. But, in fact, since bacteria are extremely diverse, it is unlikely that most types of bacteria hibernate regularly.
Which one of the following most accurately expresses the overall conclusion of the argument?
