Q. Read the following passage given below and answer the questions that follow:
1. When Man first began to settle down, to live in groups in villages and to cultivate land, he found that he had to leam
many new skills. One of these new skills was the ability to measure, to count and to calculate. He had to be able to
count the animals he processed. He had to be able to make simple measurements to enable him to build and to mark out the boundaries of his land; he had to be able to measure the passing of time and record it, and he had to trade. Therefore,
he began to think in terms of length, breadth, time and weight.
2. For many years, units of measurement were of a simple kind For example, if Man had to measure, be used a part of
its body as a unit. As a result, these wits often differed from person to person. Therefore, when Man settled down, the
need of standardisation arose.
3. Before Man settled down, his life was not governed by the seasons, nor did he have to know what time of the day it
was. Once he settled down to the agricultural way of life, he had to able to calculate the change of seasons on which
agriculture depended. So man began to measure time and first he looked for convenient units of measurements, one of
which was the day. No one knows when Man first began to divide the day into twenty-four hours and the hour into sixty
minutes. But we know that Ptolemy, the famous Egyptia, used ad recorded these divisions in the second century A.D.
In order to calculate the passing of time, it was necessary for Man to record the number of days in each season. This
was done by making a mark for each day on a tree trunk or on a piece of stick.
4. The next step was for Man to find longer units of time. He had observed the gradual changes in the shape of the
moon. He discovered that from one full moon to the next it took twenty eight days. And so he had another unit of
time a month. Then he observed that, if he added two days to some of the months, twelve of them nearly covered the
four seasons which followed each other. This was the first simple calendar.
