Final answer:
The rabies virus can infect any mammal, indicating a wide host range, whereas the human cold virus typically only infects humans, implying a narrower host range.
Step-by-step explanation:
The host range of a virus refers to the variety of species that the virus can infect. The rabies virus, which is a member of the rhabdovirus family, has a relatively wide host range; it can infect any mammal, which includes a variety of animals like bats, raccoons, dogs, cats, and humans. On the other hand, viruses that cause the common cold, such as rhinoviruses (members of the picornavirus family), typically have a narrower host range that is often limited to humans because they rely on specific cell-surface receptors that are not present in other species. Therefore, the correct answer to the question is: 1) The host range for the rabies virus is wider than that of the human cold virus.
