Answer:
Source A: Mary Cooper’s Diary - Primary source of data
Source B: Women’s Roles Article - Secondary source of data.
What is a Primary & Secondary source?
A Primary source of data means an information that is gotten straight from the person that has the experiences. This is not from other people but right from the Mary Cooper herself.
Given that she wrote this diary on her own, we can regard it as a primary source because the information is passed down straight from her on the experiences that she has had.
A Secondary source of data means the data that is collected by someone other than the primary user and this includes sources such as books, personal sources, journals, newspapers etc
Given that the Women’s Roles Article involves different collections of data from different primary sources of information to make a complete article, it is an example of Secondary source.
