A team of researchers from the Massa­chusetts Institute of Technology studied the effects of yogurt on mating. The researchers took a group of 40 male mice and 40 female mice and either fed the animals a high-fat, low-fiber, low-nutrient diet meant to mimic junk food or fed them standard mouse meals. They then supple­mented half of each diet group with vanilla-flavored yogurt.In mating experiments, yogurt-eating males inseminated their partners faster and produced more offspring than control mice. Conversely, females that ate the yogurt diets gave birth to larger litters and weaned those pups with greater success. The researchers concluded that the probiotic microbes in the yogurt help to make the animals leaner and healthier, which indirectly improves sexual machismo.

Which of the following if true, would most weaken the conclusion reached by the researchers?

A.Many of the mice in the control group died soon after the experiment
B.In another study, probiotic microbes were not found to produce any significant health benefits
C.Yogurt is not the only food which contains a high concentration of probiotic microbes
D.Mating advantage of the yogurt eating mice reduced in a few days after they stopped taking yogurt
E.The female yogurt eating mice were healthier than their male counterparts
