Figure 3.1 shows three rings of circles with letters in them. Some of these letters in each ring can form the name of one wool yielding animal. Find the names of these animals.
(1) In the innermost ring, the letters Y, A, K form the name of wool-yielding animal. Thus the name of animal is YAK.
(2) In the middle ring, the letters C, A, M, E, L form the name of wool yielding animal. Thus the name of animal is CAMEL.
(3) In the outermost ring, the letters S, H, E, E, P form the name of wool yielding animal. Thus the name of animal is SHEEP.
