Which phrase signals contrast?

• A. Because
• B. For example
• C. On the other hand
• D. In contrast

Answer: (D)

Signals that show contrast in writing help the reader notice a difference between ideas. The phrase that signals contrast most clearly is "In contrast" because it explicitly tells the reader that what follows will be different from what came before, setting up a direct comparison between two statements. It’s a straightforward cue that a shift in perspective or result is about to be presented.

For example: "Some plants thrive in full sun. In contrast, these shade-loving species grow best under trees." This makes the contrast unmistakable.

Other options work differently: "Because" explains reasons, not differences. "For example" introduces an illustration or instance, not a contrasting idea. "On the other hand" also signals a contrast, but it’s a bit less direct and often introduces an alternative view rather than a straightforward difference. The clearest, most universal cue for contrasting ideas is "In contrast."
