Leib Lurie never intended for his company, message delivery service One Call Now, to be pet-friendly. But his dog, Ivy, had other ideas.
Five years ago, the German shepherd showed up unannounced at One Call Now’s Troy, Ohio-based office—a 1.5-mile trek from Lurie’s home. When he continued to make the trip each day he wasn’t brought to the office, Lurie realized it was time for a change in company policy. Today, four or five employee’s dogs, as well as a variety offish, birds, and other caged animals join Ivy in the office daily to make One Call Now a workingman’s menagerie (动物园).

The toothed whales or odontocetes (sperm whales and porpoises) are much more vociferous than the whalebone whales, or mysticetes. In this country observers have recorded only occasional sounds from two species of mysticetes (the humpback and right whale). A Russian cetologist reports hearing sounds from at least five species of whalebone whales but gives no details of the circumstances or descriptions of the sounds themselves. Although comparison of the sound-producing apparatus in the two whale groups cannot yet be made, it is interesting to note that the auditory centers of the brain are much more highly developed in the odontocetes than in the mysticetes, in fact, to a degree unsurpassed by any other mammalian group.
Which of the following animals has the most highly developed auditory center in the brain
A. Elephants.
B. Humpback whales.
C. Racoons.
D. Sperm whales.
