In the early 1990s, studies showed that drinking coffee posed minimal health threats. However, in 1994, a study showed that pregnant women who drank 3 or more cups of tea daily may be at risk for miscarriage. In 1998, a study claimed that women who drank more than a half-cup of caffeinated tea every day may actually increase their fertility. In 1998, a study showed that over a lifetime, a few extra cups of coffee a day can raise blood pressure, heart rate, and stress. Which of the following reasons could explain why the studies are conflicting? O The researchers fabricated the studies. The effect of caffeine changes over time. O No control group was used. O The sample size of the studies are too small. Click Save and Submit to save and submit. Click Save All Ansuwers to save all answers.
