The sentence that contains subjective information and makes it objective is the following:
B. The thirty-one year-old widow Mary Pickersgill and her daughter, Caroline, moved to the corner house at Albemarle and Queen (now Pratt) streets in the heart of Old Town, Baltimore, Maryland, in 1807. (Paragraph 1).
It is known that subjective information is based on personal criteria and interpretation. In the original example of the sentence, the reader can have his or her own opinion about what the age a "young widow" can be. On the other hand, objective information is based on facts, analysis and reliable data. Thus, if Mary Pickersgill's age is given in the text; there is no place for the reader's personal interpretation.
