Which signal word indicates an example is about to be provided?

• A. Consequently
• B. However
• C. For example
• D. But

Answer: (C)

The choice "For example" is the signal word that directly indicates an example is about to be presented. This phrase acts as a cue to the reader or listener that the information that follows will illustrate or clarify a previous point by providing specific instances or cases. It serves the purpose of enhancing understanding by offering concrete details that relate to the broader concept being discussed.

The other terms listed do not serve this purpose. "Consequently" suggests a result or effect, whereas "However" indicates a contrast or exception to what has been previously stated. Similarly, "But" functions to introduce an opposing idea or a shift in perspective, rather than to provide an illustrative example. Therefore, "For example" is the clear choice when looking for a word that signals the introduction of illustrative content.
