The variable is the group that was given caffine, because thats what the doctors manipulated. They possibly altered the natural memory of the participants by giving them caffine. A more specific variable could be how much caffine each participant is given and what time are they given it.

Good morning/evening everyone,
My name is (your name) and I am here today to talk upon and important school tradition failure. It has been brought to my and other students' attention that there is not enough funding for the school yearbooks. School yearbooks are a trademark that most/all schools do. Usually yearbooks are sold and the school is able to recieve some or most of that additional funding back. They are made to remember that year. They have pictures of our fellow classmates, even though half of us want to retake them because of that imperfection that decided to visit, I know i do. (smile/ giggle) The yearbook includes pictures from our rallies, dances, or even friends that beg the photographer to get a picture of them. When all is said and done, yearbooks are memories for you and for us. Im sure you all still have your yearbooks and glance at them from time to time to remember those silly/fun times. This concludes my speech and I hope you all can just think about it a bit more. Thank you for your time. (backflips off stage) jkjk but goodluck! <33
