Which transition would appropriately indicate a point of contrast?

The appropriate transition that indicates a point of contrast is "On the other hand." This phrase is commonly used to present a differing viewpoint or counterargument to something previously mentioned. It signals to the reader that what follows will be a contrast or a different perspective, effectively highlighting the distinction between two ideas or situations. Using "On the other hand" helps to create a clear contrast between two sides, allowing the reader to easily follow the argument or discussion.

In contrast, terms like "In fact," "As a result," and "To summarize" serve different purposes. "In fact" typically reinforces or emphasizes a point rather than contrasting it. "As a result" indicates a cause-and-effect relationship, showing the outcome of a particular situation or action. "To summarize" is used to encapsulate or restate information rather than present a contrast. Hence, "On the other hand" is uniquely suited to indicate opposition or differing views.
