Which phrases are examples of cause and effect?

The choice that includes "because" and "as a result" serves as a clear indication of cause and effect relationships in sentences. The word "because" introduces a reason or cause for a situation, while "as a result" describes the effect or outcome that follows that cause. This pairing illustrates how one event or action leads logically to another, effectively communicating the connection between the two parts of a statement.

On the other hand, the other options contain words that do not inherently imply a causal relationship. For example, "however" and "nonetheless" signify contrast, while "before," "after," and "next" are terms that sequence events without going into their causality. The word "therefore" indicates a conclusion but does not specify a cause itself; "in addition" implies addition rather than cause.
