In a typical compaction curve as indicated in the diagram, points 'A: and 'B' have the same dry densities. Choose the most appropriate statement from the following:
1
Soil at 'A' will have more swelling potential and less shrinking upon moisture variation, compared to 'B'.
2
Soil at 'A' will have same swelling and shrinking potential as soil at 'B'.
3
Soil at 'A' will have less swelling potential and higher shrinking potential compared with soil at 'B'.
4
The swelling-shrinking potential for soil at 'A' and 'B, cannot be predicted with the given data
