Context: In response to my recent post on concentrated soaps , Sue writes : Bob & I had a discussion after your last post on this topic . We had a large bottle of concentrated soap , and a small soap bottle empty . So we filled the empty bottle to the 1/4 mark with the concentrate , and diluted it 3:1 with water .

Option 0: Because they do n't have much soap
Option 1: To save money
Option 2: Because someone told them to
Option 3: None of the above choices .
Answer: 1
