The word "ensuing" means to occur just after an event. This implies that something happens immediately or directly following another event. It suggests a chronological order or sequence of events, where one event leads to the next. The other options, such as "never ceasing; continual," "a large sheet of waterproof canvas or plastic," and "to pass through; penetrate," do not accurately capture the meaning of "ensuing" as they do not convey the idea of something happening after another event.
