Which of the following is not true about the camel's hump?

Reading Passage: CAMEL
Directions: Read the passage carefully:
The camel is the oldest of domestic animals. It has been used for thousands of years, by the desert people of Africa and Asia to supply many of their needs. On the fertile edges of the desert, camels pull ploughs, turn wheels to irrigate the fields and carry goods to the market. In the desert itself, they are still almost the only means of transport. They supply food, milk and clothing in the form of wool and leather.
This useful animal is well adapted to life in harsh, arid lands. The Arabian camel has one hump; the Bactrian camel has two. The hump is, in fact, a store of fat which is used as a source of energy when food and water are scarce. When it does drink, the camel can take up to 100 litres of water in ten minutes.
The camel has broad, soft feet for a steady grip in the sand. A thick skin protects it from the fierce daytime sun and bitterly cold nights. The camel's eyes have three eyelids to help keep out sand; its ears and nose are also adapted to keep out sand storms. Camels stand about two meters high at the shoulder and weigh 500-800 kilos.
Often called the ship of desert; they can carry loads of 200 kilos and more, travelling up to 16 kilometres a day. Camels eat grass, dates and grain when available. Deep in the desert they survive on dry leaves, seeds and oats.

  1. It stores water.

  2. It stores body fat.

  3. It contains the energy source that the camel uses in the absence of food and water.

  4. It helps the animal to adapt to different conditions.
