Read the following passage carefully and answer the questions given below:
Another group of diseases is due to food
which does not contain enough of one or another of vitamins. The first diseases
which were conclusively shown to be of this kind were scurvy and beri-beri. The
former was common among sailors who were restricted to such food as ship’s
biscuits and salted meat on long voyages. The latter is mainly found in rice
eating countries such as Java and Japan.

good deal of suffering and a certain number of deaths. Later, rickets fell into
