B. as a result

The transitional phrase that would most likely be used in an expository text with a cause-and-effect structure is "B. as a result".

To determine which transitional phrase would most likely be used in an expository text with a cause-and-effect structure, you need to first understand the purpose of transitional phrases. Transitional phrases are words or phrases that help connect ideas or sentences, making the text flow smoothly and allowing readers to understand the relationships between different parts of the text.

In the case of a cause-and-effect structure, the text aims to explain the relationship between a cause and its resulting effect. The transitional phrase should indicate this cause-and-effect relationship.

Now, let's examine the given options:

A. In contrast: This transitional phrase is used to compare or highlight differences between two or more things. It does not indicate a cause-and-effect relationship.

B. As a result: This transitional phrase is commonly used to show the direct consequence or outcome of a preceding event or action. It is frequently used in texts with a cause-and-effect structure. Thus, "as a result" is the most suitable choice for this question.

C. To solve: This transitional phrase introduces an action or solution that is intended to address a problem or issue. It does not directly indicate cause-and-effect.

D. In the same way: This transitional phrase suggests that two or more things are similar or comparable. It does not specifically indicate cause and effect.

In conclusion, option B, "as a result," would most likely be used in an expository text with a cause-and-effect structure because it clearly signifies the cause-and-effect relationship between events or actions.
