Answer :
Final answer:
The claim about the French Revolution instituting a decimal calendar and timekeeping system based on ten is true.
Explanation:
The statement about a new decimal calendar and a method of telling time based on units of ten during the French Revolution is true.
The French revolutionaries did indeed adopt a new calendar system and timekeeping method that was largely based on the number ten. This radical change was part of a broader movement to decimalize various aspects of life and standardize units of measurement during the period of the French Revolution.
In this decimal calendar system, a week consisted of ten days, which were named after the decimal units such as Primidi, Duodi, etc., instead of the traditional seven. Each day was divided into 10 hours, each hour had 100 minutes, and each minute had 100 seconds. However, this system did not last long and was eventually abandoned as it was impractical for everyday use and was not widely accepted by the population.
It is interesting to note that this change was part of a broader attempt by the new revolutionary government to break from the past and establish a new order. Other reforms included the adoption of the metric system and measures to de-Christianize society, including changing the names of the months and redesigning the yearly calendar.
