Do you think the classification of economic activities into primary, secondary and tertiary is useful? Explain how?

Yes, in my opinion, the classification of economic activities into primary, secondary and tertiary sectors is very useful because classification will help us in identifying which activity is related to which sector. And besides this there are several reasons as follows:

a) The very first point which will be known that how many people and where are they employed in any country.

b) If development will be seen only in the tertiary sector, then it means that agriculture which is related to the primary sector is deducting day by day and by noticing the rise and fall in both sectors government will be able to take strong action towards the improvement wherever it is required.

This is why to improve the sectors and to run the economy smoothly, and for best administration and development, classification of economic activities is necessary.
