7. The American Museum of Natural History in New York City contains more than 32 million specimens and artifacts in its various collections, including the world's largest collection of dinosaur fossils. Many of these are in storage away from public view, but all must be carefully inventoried.

2. b. Assuming the inventory is sorted, about how much time would a binary search require?
