. At the Shadybrook dog kennel, all the adult animals were given a new medi-

cation designed to reduce a dog’s risk of contracting a certain common

infection.  Several days after the medication was administered, most of the

puppies of these dogs had elevated temperatures.  Since raised body temp-

erature is a side effect of this medication, the kennel owner hypothesized

that the puppies’ elevated temperatures resulted from the medication’s being

passed to them through their mothers’ milk. 

 Which of the following, if true, provides the most support for the kennel owner’s

hypothesis?

     A  Some puppies have been given the new medication directly but have not

       suffered elevated temperatures as a side effect. 

   B   The new medication has been well received by dog breeders as a safe

       and effective way of preventing the spread of certain common canine

       infections. 

   C   None of the four puppies in the kennel who had been bottle-fed with for-

       mula had elevated temperatures. 

    D  An elevated temperature is a side effect of a number of medications for

       dogs other than the new medication administered at the kennel. 

   E  Elevated temperatures such as those suffered by most of the puppies

       in the kennel rarely have serious long-term effects on a puppy’s health.
