Directions: In the following question, four statements are provided between an opening statement 1 and a closing statement 6. The four statements are jumbled up and form a coherent paragraph when properly arranged. Select the alternative representing the proper and logical sequencing of these six taken together.

1. The relations of different nations among themselves depend upon the extent to which each has developed its productive forces, the division of labour and internal intercourse.
   

A. But not only the relation of one nation to others, but also the whole internal structure of the nation itself depends on the stage of development reached by its production and its internal and external intercourse.

B. The division of labour inside a nation leads at first to the separation of industrial and commercial from agricultural labour, and hence, to the separation of town and country and to the conflict of their interests.

C. Each new productive force, insofar as it is not merely a quantitative extension of productive forces already known (For instance, the bringing into cultivation of fresh land), causes a further development of the division of labour.

D. How far the productive forces of a nation are developed is shown most manifestly by the degree to which the division of labour has been carried.

1. Its further development leads to the separation of commercial from industrial labour.
