Is measurement and counting necessary? Explain giving one or two examples. 

Measurement or counting is necessary as the knowledge without counting is inadequate and unsatisfactory. Measurement will make the understanding of the object easier. 

For instance, suppose you go to a tailor to get trousers stitched. If the tailor stitches them without taking your measurement it would be ill-fitting and look shabby. Similarly, if you order a door to be made by a carpenter, without measurement, the door may not fit in the opening allowed for it. Taking the measurement or counting is always advised for an easier understanding.
