Adecomposed body was found in a shallow grave in an open field in october. the body had traces of grass and ragweed pollen. in that area, ragweed blooms in april through late may, while grass sheds pollen from may through august. which is the best conclusion?
a) the victim died in september
b) the victim died in may
c) the victim died in july
d) the victim died in april

The correct answer is May.

There are traces of grass and ragweed in the decomposed body of a victim. The common month for the growth of the ragweed and grass is May. If the body could have died before may then there would have been no traces of ragweed and if the body would have died after august then there would have been no traces of grass.

So, as the body has both the traces of ragweed and grass the body could have died in the month of May.
