Agroup of scientists is attempting to verify recent data published on the chemical composition of tears and the presence of alzheimer's disease. this illustrates the critical thinking principle of

replicability

Explanation:

According to my research on the experimental process, I can say that based on the information provided within the question this illustrates the critical thinking principle of replicability. This is the ability to reproduce certain the same results using the same process. We can say this is the principle being illustrated because the scientists are trying to verify the data published, and the only way to verify the data is to copy the same experiment and see if the data produced is the same as the one published.
