Which transition best signals a contrast between two ideas in a paragraph?

• A. Similarly
• B. In contrast
• C. For example
• D. Additionally

Answer: (B)

Transitions guide how readers move from one idea to another. To signal a contrast, you need a word that flags difference. “In contrast” does exactly that, telling the reader that the next idea will differ from what came before and highlighting the difference clearly. For example: some plants tolerate drought; in contrast, others require regular watering. This contrast cue makes the relationship obvious.

The other options serve different purposes: “Similarly” shows similarity or continuation of the same idea; “For example” introduces a specific instance to illustrate a point; “Additionally” adds more information, expanding on a point rather than opposing it. Therefore, the best choice to signal a contrast is “In contrast.”
