Consider the time Charlene Jendry, a conservationist at the Columbus Zoo, learned that a female gorilla named Colo was handling a suspicious object. Arriving on the scene, Jendry offered Colo some peanuts, only to be met with a blank 【A1】______. Realizing they were negotiating, Jendry raised the 【A2】______ and offered a piece of pineapple. At this point, while maintaining eye 【A3】______, Colo opened her hand and revealed a key chain. 

Relieved it was not anything dangerous or valuable, Jendry gave Colo the pineapple. 【A4】______ bargainer that she was, Colo then broke the key chain and gave Jendry a link, perhaps figuring, why give her the whole thing if I can get a bit of pineapple for each piece? 

If an animal can show skill in trading one thing for another, why not in 【A5】______ money? One orangutan named Chantek did just that in a sign-language study 【A6】______ by anthropologist Lyn Miles at the University of Tennessee. Chantek figured out that if he did tasks like cleaning his room, he’d earn coins to spend on treats and rides in Miles’s car. But the orangutan’s understanding of money seemed to 【A7】______ far beyond simple dealings.

Miles first used plastic chips as coins, but Chantek decided he could expand the money 【A8】______ by breaking chips in two. When Miles switched to metal chips, Chantek found pieces of tin foil and tried to make copies. Miles also tried to teach Chantek more 【A9】______ habits such as saving and sharing. Indeed, when I caught up with the orangutan at Zoo Atlanta, where he now lives, I saw an example of sharing that anyone might envy. When Miles gave Chantek some grapes and asked him to share them, Chantek 【A10】______ ate all the fruit. Then, as if he’d just remembered he’d been asked to share, he handed Miles the stem.
