One can infer from the passage that --- .

There are two general kinds of milk available: whole milk and concentrated milk. Whole milk has all the nutrients of milk. It is usually 2 to 4 percent butterfat and 8.5 percent milk solids. The rest is water. When some or all of the water removed from the milk, the product is called concentrated milk. There are three main types of concentrated milk; evaporated, dehydrated and condensed. Evaporated milk, which is very thick, has only 40 percent of its water. It usually comes in cans. Dehydrated milk has no water. It is a dry powder that usually comes in boxes. Condensed milk is evaporated and sweetened. It is about 42 percent sugar. People choose which kind of milk to buy depending on their needs.
