Context: My first thought was to check the fridge because my milk must be leaking , but this proved not to be the case . I opened the fridge and the milk bottle was standing in its usual place ( in the door of the fridge ) , lid on , no dripping holes , not sat in a pool of its former contents . I then searched round the house to see if anything was missing or had been moved , and if whoever or whatever was responsible was still around somewhere .

Question: What may happen during this situation ?
Options:
0. They will buy a new gallon of milk .
1. They will question their family members about the liquid .
2. They will look for signs that someone was in their home .
3. None of the above choices .
Answer: 2
