roberto is conducting research about the ethics of confining animals in zoos. which source on his list is the most credible?\n a site where people share stories about their experiences in zoos and their feelings about zoos\n a research study published on a universitys website about how being in a zoo affects animals\n an advertisement for a family vacation package that includes an amusement park and zoo\n a blog where a zoo owner discusses everyday life working at a zoo and caring for animals
Answer
Answer:
a research study published on a university’s website about how being in a zoo affects animals
Brief Explanations:
A university - published research study is likely peer - reviewed and based on scientific methods. A site with personal stories (subjective), an advertisement (biased for promotion), and a zoo owner’s blog (potentially biased) are less credible than a university - based research study.
