If Grandma baked a cake.
- Can scientists determine exactly what she did?
(I know that they can do: Chemical Analysis, Isotopic Dating, Texture and Appearance and Microscopic Examination. Alternatively, we can read her recipe.)
- Can we determine exactly when she sifted the flour?
(I know we can determine whether the flour was sifted before she used it, but not exactly when. If she did not specify this to the 't', we cannot know.)
- Why did she bake the cake?
(I know we'll need to ask grandma.)
