An archaeologist draws a stratigraphic profile of a site with three clearly defined strata. In her drawing, level A comprises the bottom layer, with level B resting on top of level A. Level C, a pit, starts at the top of level B and extends down into level A. Is level C younger or older than level B, and why do you think so? A. Level C is younger than level B, because level B had to exist first, before level C could intrude upon it and level A. B. Level C is older than level B, because it comes into contact with level A, which is the oldest of the three C. There is no way to tell which level is older, based on this description D. Level C is younger than level B, because the archaeologist noticed it before noticing level B
