The words that may infer a cause and effect in a sentence are letters B. Before and C. Consequently. ‘Before’ states the cause, what happened in the past that induced the happening now. What were the happenings that were overlooked or actions taken by a certain community to achieve or for not achieving its present status now. ‘Consequently’ is the result. It gives you the now the effect of the accumulated deeds before. It gives you the current status and how what are the needed steps to go about it.
