A certain viral infection is widespread among children, and about 30 percent of children infected with this virus develop middle ear infections. Antibiotics, although effective in treating bacterial infections, have no effect on the virus. Yet when middle ear infections in children infected with the virus are treated with antibiotics, the ear infections often clear up.
Which one of the following most helps to explain the success of the treatments with antibiotics?
(A) Although some types of antibiotics fail to clear up certain infections, other types of antibiotics might provide effective treatment for those infections.
(B) Children infected with the virus are particularly susceptible to bacteria that infect the middle ear.
(C) Many children who develop middle ear infections are not infected with the virus.
(D) Most viral infections are more difficult to treat than are most bacterial infections.
(E) Among children not infected with the virus, fewer than 30percent develop middle ear infections.
