The correct answer to this open question is the following.
According to your question, there are only two parts to be answered, a) and b).
Being that the case, we can comment on the following.
A) This is an observational study and not an experiment because the research was only limited to observation, participants never receive any kind of treatment or another interaction to experiment with them.
B) Who were the subjects of the study?
The subjects of this study were women aged 65 and older who were tracked for several years. The observation revealed that those women who had a vitamin B12 deficiency were twice as likely to suffer severe depression as those who did not.
So, according to the American Journal of Psychology, these were the women observed during the study. There were no more experiments, interactions, or activities applied to them in order to consider it an experiment.
Let's remember that in order to consider an experiment as such, there has to be another component of the study, and the experimental part of it that has to be tested and proved passing the scientific method to conclude in something valid.

Answer:
The institution of slavery usually tried to deny its victims their native cultural identity. Torn out of their own cultural milieus, they were expected to abandon their heritage and to adopt at least part of their enslavers’ culture. Nonetheless, studies have shown that there were aspects of slave culture that differed from the master culture. Some of these have been interpreted as a form of resistance to oppression, while other aspects were clearly survivals of native culture in the new society. Most of what is known about this topic comes from the circum-Caribbean world, but analogous developments may have occurred wherever alien slaves were concentrated in numbers sufficient to prevent their complete absorption by the host slave-owning or slave society. Thus slave culture was probably very different on large plantations from what it was on small farms or in urban households, where slave culture (and especially Creole slave culture) could hardly have avoided being very similar to the master culture. Slave cultures grew up within the perimeters of the masters’ monopoly of power but separate from the masters’ institutions.
