Which phrase serves as a transition in a sentence?

The phrase "In the meantime" serves as a transition in a sentence by indicating a temporal relationship between events or actions. It helps to connect two ideas by showing that something is happening concurrently or during the period between two other events. This transitional phrase aids in guiding the reader through the sequence of thoughts or actions, making it clear that while one thing is occurring, another is also relevant.

The other phrases, while they can work as transitions, serve different purposes. "To summarize" typically introduces a recap of previously mentioned information, rather than bridging two ongoing actions. "Furthermore" adds information that builds upon a previous point, expanding on an idea rather than indicating timing. "For example" introduces an illustrative case or instance to clarify a point, rather than providing a chronological connection. Thus, "In the meantime" distinctly fulfills the role of a temporal transition, effectively linking ideas in a way that enhances the flow of information in the text.
