Final answer:
Option A ('The author of this paragraph likes bananas...') fails to provide an objective summary and inaccurately projects a personal opinion onto the author regarding the banana trade.
Step-by-step explanation:
In terms of objectivity in summarizing the provided information about the banana trade, Option A falls short of being objective. This summary inaccurately ascribes a personal opinion to the author ('The author of this paragraph likes bananas') without any evidence from the text. Instead, the paragraph describes the technological advancements that facilitated the transportation of bananas to America and Europe.
Options B, C, and D offer more objective summaries, but specifically, Option C ('Before 1850, most Americans and Europeans had never had the opportunity to taste a banana') and Option D ('The technological developments of the Industrial Revolution helped create a global banana trade') are directly supported by the text.
