Identify the sentence that uses a cause and effect relationship

There are several ways to identify a sentence that uses a cause and effect relationship. The most common indicators are conjunctions such as "because," "since," "as a result," "therefore," "so," or "thus". These conjunctions typically link the cause with the effect, showing the relationship between the two.

For example, consider the following sentences:

1. "Because it was raining, the ground became wet."
2. "Since she studied hard, she passed the exam."
3. "He ran out of gas; as a result, he couldn't reach the destination in time."

In these examples, the cause (raining, studying hard, running out of gas) is connected to the effect (ground became wet, passing the exam, not reaching the destination in time) by the use of conjunctions. These sentences clearly demonstrate a cause and effect relationship.
