Answer question 14-26 Based on the given reading Passage-

1. Betty and her mate Abel are captive crows in the care of Alex kacelnik , an expert in animal behavior at Oxford University.
They belong to a forest- dwelling species of bird confined to two islands in the south Pacific . New Caledonian crows are tenacious predators and the only birds that habitually use a wide selection of self made tools to find food.

2. One of the wild crow’s cleverest tools is the crochet hook,made be detaching a side twing from a larger one , leaving enough of the larger twing to shape into a hook . Equally cunning is a tool crafted from the barbed vine leaf , which consists of a central rib with paired leaflets each with a rose like thron at its base . They strip out a piece of this rib , removing the leaflets and all but one thron at the top , which remains as a ready made hook to prise out insects from awkward cracks.

3. The crows also make ab ingenious tool called a padanus probe from padanus tree leaves. The tool has broad base, sharp tip, a row of tinny hooks along one edge, and a tapered shape created by the crow nipping and tearing to from a progression of three or four steps along the other adge of the leaf.

Are cut. The remarkable thing that these counterpart leaves tell us that crows consistently produce the same design every time, with no in-between or trial versions. It’s left the researchers wondering whether , like people, they envisage the tool before they start and perform the actions they know are needed to make it.

4. In a test at Oxford , kacelniks team offered Betty and Abel an original challenge – food in h bucket at the bottom of a well . The only way to get the food was to hook the bucket out by its handle.

5. But do they also have the foresight and creativity to plan the constitution of their tools ? It appears they do. In one bucket -in-the-well test. Abel carried off the hook , leaving Betty with nothing but the straight wire. What happened next was absolutely amazing , says kacelnik. She wedged the tip of the wire in to a crack in a plastic dish and pulled the other end to fashion her own hook.
