Which choice below best explains the differences in the tone and style of the two passages?
1) Passage A is about past events, which requires an old-fashioned style that was used at the time those events took place. Passage B is about current events, so it uses modern slang.
2) Passage A is a business publication, so it is written in the third person. Passage B takes a more human view, so it is written in the first person.
3) Passage A is a scientific document, so it appeals to logic and uses technical language. Passage B is a self-help article, so it is written with emotional and encouraging language.
4) Passage A is historical, so it describes past events in terms of cause and effect. Passage B gives advice and uses a list of do's and don'ts to get the point across.
