an individual claims to be able to detect the presence of graves in an old cemetery by using a \dowsing\ or \divining\ rod. the rod is a forked twig held out in front of the individual as he walks across the cemetery. the \dowser\ claims that depending on which way the twig moves (up and down or side to side) he can determine if there is a grave there, and the gender and age of the individual buried at that spot. which of the following would not help you to evaluate if the dowser is a charlatan?
it would help to know the dowsers age and affiliation with other dowsers.
it would help to actually dig up the site to determine if the dowsers predictions were accurate.
it would help to at least use x - rays or some other means to examine what might, or might not, be buried in the ground.
it would help to know if the dowser had any previous knowledge of the cemetery.

Explanation:

To evaluate if the dowser is a charlatan, we need to check the accuracy of their claims. Knowing the dowser's age and affiliation with other dowsers does not verify the accuracy of their dowsing - related predictions. Digging up the site, using X - rays or other means to examine the ground, and knowing if the dowser had prior knowledge of the cemetery can all help in assessing the validity of the dowser's claims.

Answer:

It would help to know the dowser's age and affiliation with other dowsers.
