Scientific journal: Recent testing was conducted to examine the health benefits of drinking milk and what effect it has on calcium levels in women over the age of forty. The test was conducted on 200 women in similar states of health over the course of three months. The women were asked to drink two eight-ounce glasses of milk each day. All participants followed this stipulation closely. Results show that 75% of the women showed a mild increase in calcium levels, whereas 25% of the women showed a sharp improvement in calcium levels.
Which of the following, if true, most explains the inconsistency among study participants in their testing results?
(A) Twenty-five percent of the women drank whole milk each day, whereas the other 75% chose to drink low-fat milk.
(B) Seventy-five percent of the women were suffering from osteoporosis and thus did not absorb as much of the calcium from the milk.
(C) Seventy-five percent of the women were over the age of fifty, whereas the other 25% were under the age of fifty.
(D) Twenty-five percent of the women were taking a multi-vitamin with added calcium in addition to drinking two eight-ounce glasses of milk each day.
(E) Seventy-five percent of the women had given birth, while the other 25% had never had children.

The Question is pretty tough I think, however I believe the answer could be B or D. But I would go with D as D is directly explaining the difference. While B says Low increase in 75% due to certain condition as they were not able to absorb calcium, but we don’t know anything about why 25% was high... Option D directly says that an external factor was responsible for high calcium increase.
Please explain if my reasoning is correct.

A close one. One of the key errors in the answers can be that we don't know if the 25% talked about in the answers is the same 25% that is referred as the high calcium group in the question.
(A) Twenty-five percent of the women drank whole milk each day, whereas the other 75% chose to drink low-fat milk.
--> Milk differentiation isn't talked about in the passage hence it would be a "may or may not be" option
(B) Seventy-five percent of the women were suffering from osteoporosis and thus did not absorb as much of the calcium from the milk.
--> This marks a clear distinction between the two groups, however small it is. A probable answer.
(C) Seventy-five percent of the women were over the age of fifty, whereas the other 25% were under the age of fifty.
--> Since the survey is for people above 40, this may not come out as a strong reason for the difference.
(D) Twenty-five percent of the women were taking a multi-vitamin with added calcium in addition to drinking two eight-ounce glasses of milk each day.
--> This is again a "may or may not be". If the calcium percentage is high in the multivitamin and everything else assumed good, we can say this can be the reason but if the calcium percentage is very low in the multivitamin, we can't be sure if this made any difference. Still a probable answer.
(E) Seventy-five percent of the women had given birth, while the other 25% had never had children.
--> This isn't a variable in the stem hence cannot comment on its viability without additional data.
Among B and D, I'll side with B as it assures me of a positive difference in outcome when the same input (milk for the 200 women). While C may or may not give me the intended results. In fact, D can fail to produce results if B is true.
