Question

Read the following information and prepare any two questions.
Finally in France, it was decided that a certain length of rod made of a special
material (platinum-iridium) would be called a metre. The metre was divided into
100 equal parts and these parts were called centimetre. Each centimeter was
further divided into ten equal parts called millimetre. Now we are using this as a
standard measurement for length through out the world. This original scale is
preserved in a museum in France.​

Answer 2

The history of the metre starts with the scientific revolution that began with Nicolaus Copernicus's work in 1543. Increasingly accurate measurements were required, and scientists looked for measures that were universal and could be based on natural phenomena rather than royal decree or physical prototypes. Rather than the various complex systems of subdivision in use, they also preferred a decimal system to ease their calculations.
