Final answer:
Option (a) 'because, as a result, therefore, due to' contains the words that signal a cause-and-effect relationship in texts. These words link a cause directly to its effect and are essential for constructing coherent paragraphs in cause-and-effect writing.
Step-by-step explanation:
Texts that exhibit a cause-effect structure use specific signal words to indicate the relationship between causes and effects.
Among the options listed, option (a) 'because, as a result, therefore, due to' are the words that are most commonly associated with expressing cause and effect, as they directly link a cause with its subsequent effect.
Option (b) includes words that signal sequence rather than causation. Similarly, options (c) and (d) mix sequence and cause-effect signal words.
In cause-and-effect writing, it is important to identify both the reasons (causes) for and the consequences (effects) of an action, event, or idea.
For example, a cause might be 'vehicles sped without regard to the speed limit,' while the effect could be 'a traffic signal was installed.' Phrases such as 'Because of this...,' 'Due to...,' 'Therefore...,' and 'As a result...' help to make these connections clear to the reader.
Understanding the appropriate use of cause-and-effect signal words is essential for constructing coherent paragraphs that explain how one event leads to another.
These connecting words guide the reader through the logic of the events being described, ensuring the cause-and-effect relationship is understood.
