Answer:
placebo control group
Explanation:
In order to determine that a drug has any effect in the body participants of a study are divided into two groups a group which actually receives the treatment and the other group receives a fake treatment. The participants are unaware of which group they belong to.
The fake treatment group is called the placebo control group. If the drug is actually effective then the placebo control group should not shoe the same effects that the treatment group is showing.
Here, the capsule received by group 2 looks like the capsule with the Ginkgo Biloba herb. The participants of group 2 should not show an increased blood flow to the brain. The participants of group 1 should show an increased blood flow to the brain. This would prove that the Ginkgo Biloba increases blood flow to the brain.

A Story about history, and how it affected us….Before 2012, many people believed that the year 2012 was going to be the end of the world. This prediction was based off of the Mayan Calendar, a primary source of its own, made at ~August 11, 3114 BC. Why is this a primary source? Because the Mayans themselves made the calendar, and based everything off of it. However, rest assure, because the world didn’t end yet. (obviously, because its like what 2017 right now [delete this ()]). Many people believed this to be true, and thousands of people rushed to get ready for this ‘end of the world’. They bought food and water in large quantities (and with their life savings) and waited out in underground shelters. The connotation of the phrase “end of the world” scares many. They never want to think of what or where the world is going, and the end of the world. Instead, they look towards the past, and try to learn lessons from the past so that they do not make the same mistakes today, because if the same mistakes happen today, well, you never know where the world will lead to tomorrow. How do they look towards the past? Well, they do NOT take bits and pieces from different timezones randomly. Instead, researchers try to find history that actually has an effect on today or tomorrow. Take for example, the world wars. People go in chronological order from even before the start of the war to a little after it, to learn of the reasons the war started, what happened during the war, and the consequences of fighting the war, and how it affects people. After that, many people would write nonfiction and fictional stories about it, sometimes adding personification to animals that “viewed” the battle while it was going on. An example of this, is “War Horse”, by Michael Morpurgo, in which a horse by the name of Joey, is given a personification, and tells us of an experience a horse had in real-life history (from a farm animal to a animal that survived WW1). With all of this information that is given to us from history, both the problems, and the resolution, it is up to us to learn what is best for our current situation, and to not make the same mistakes again. <span>
