What assumption can be made about the upcoming strike by bus drivers based on the news story?

The assumption that parents must make alternative arrangements for school travel is rooted in the practical implications of a bus drivers' strike. When bus drivers go on strike, the transportation services that facilitate students’ travel to and from school are disrupted. This necessitates that parents take initiative to find different means of getting their children to school during the strike period. This reasoning directly connects to the expected consequences of the strike, making it a logical conclusion based on the information typically presented in such news stories.

The other choices, while related to the context of a bus drivers' strike, do not directly address the immediate action parents would need to take as a result of the strike. For instance, issues affecting students' transportation could be a consequence of the strike but do not necessitate immediate action on the parent's part. The goal of a strike may include seeking better pay, but this is more about the drivers' motivations rather than the implications for parents. Lastly, the assumption that there will be no school next week doesn't logically follow from the information about a bus drivers' strike; schools may still operate, relying on alternative transportation solutions or other arrangements. Thus, the need for parents to make alternative travel arrangements is the most reasonable and direct conclusion from the scenario.
