Why would a researcher use a secondary source instead of a primary source when analyzing historical event

Because a primary resource would be an interview of someone in that event or their diary or something they wrote about that event. If you couldnt find anything, you would have to use the secondary source, a book or article written about that event but the author wasnt in it or there

Towns and small farms are usually for land, lakes, rivers, and seas.they also produce other food, like crops.it's also where animals are, where we get our meat.large plantations normally have forests, where crops are grown for sale. (similar to farms)plantations have larger fields of crops.our wine, sugar canes, and fruits come from plantations.
