Answer:
Anthropology is very widely the study of any and all human behavior. All humans also have a cultural position that anthropogists seek to understand. Limits to study design are examples where access to the subjects is restricted for example, or where participants might be engaging in illegal activities.
Explanation:
Because anthropologists study any human behavior or meaning system defined broadly, there are an infinite number of topics that anthropologists can study. Examples would be birthing practices in different cultures for example that can take a medical focus, and also the worldview of how engineers understand the environment and how they modify it. One limit on anthropological research is funding for example and studies where there are ethical lines that make it difficult like when study participants engage in illegal behaviors for example or where access to the informants is limited like with prison inmates. Some anthropological work on these issues would have to use different means of accessing the subjects, like via email or journal entries rather than direct participant-observation.
