Some scientists think that case studies are not useful because they provide information about only one person. what do you think? what is your opinion of case studies?

well i think you should consider your own opinion and not others but ill help you out. case studies are conducted with experiments over a period of time. its reliable in a way of time and evidence. but its also not very reliable in ways of only one subject. experiments in general consist of changing something particular, such as what you are researching. so, researching or experimenting on two or more different things, gives more accurate results. more subjects more research.

the conclusion would be the most affected category scoring

the correct answers are:

c. “never in the history of his people had a man married a woman who spoke a different tongue.”

d. “‘it has never been heard,’ was the verdict of an old man speaking a few weeks later.”

e. “this man had come with others to commiserate with okeke.”
