Final answer:
The sentence can be passively rewritten as 'Eyeglasses with bifocal lenses were invented by Benjamin Franklin.' The use of passive voice in scientific and historical writing adds objectivity, while active voice adds a more engaging narrative. Franklin's role as an inventor, including his development of bifocal lenses, underscores his historical significance.
Step-by-step explanation:
The sentence “Benjamin Franklin invented eyeglasses with bifocal lenses.” can be rewritten in the passive voice as “Eyeglasses with bifocal lenses were invented by Benjamin Franklin.” This change from active to passive voice shifts the focus from the subject, Benjamin Franklin, to the action and its recipient, the invention of the eyeglasses with bifocal lenses.
In both scientific writing and historical accounts, the use of passive or active voice can significantly affect the tone and focus of the sentence. Traditionally, passive voice has been used in scientific and technical fields to emphasize neutrality and objectivity, particularly in the methods and results sections of reports. Conversely, the active voice is often employed to create a more engaging narrative and is commonly seen in the introduction and conclusion sections where interpretation is key.
Renowned as an inventor, statesman, and diplomat, Benjamin Franklin's contributions, including the invention of bifocal lenses, demonstrate his ingenuity and impact on science and society. His legacy continues to influence discussions about innovation and American history.
