How did meladi and tawan deceive their zookeeper?

Answer 1

When the zookeeper put an orange down a tube, Meladi would get it and pretend not to have it to make the zookeeper think that it went down the wrong tube. But she really had it, but the zookeeper sent down another orange. While this was happening, Tawan was sitting aside watching. The next day when the zookeeper came around Tawan pretended not to get one either, so he got an extra, too. Soon after, the zookeeper found that they had tricked her. And that is for you how they deceived their zookeeper.
