Final answer:
The appropriate hashtag for a paragraph focused on cause-and-effect is 'C. Cause and Effect,' while a paragraph discussing a problem and its solution would use 'D. Problem Solution.' Identify the paragraph's main structure to choose the correct hashtag.
Step-by-step explanation:
The type of hashtag that can be used for a paragraph that explains either a cause-and-effect relationship or a problem-solution dynamic comes down to identifying the primary structure of the paragraph. If the paragraph starts by discussing a cause and then details the ensuing effects, or vice versa, then the appropriate hashtag is C. Cause and Effect. However, if the paragraph identifies a problem and then outlines potential or actual solutions for addressing this problem, the suitable hashtag is D. Problem Solution.
For instance, a paragraph that presents information such as 'Because vehicles sped without regard to the speed limit, pedestrians dodged traffic and accidents increased; for those reasons, a traffic signal was installed,' clearly illustrates a cause-and-effect situation. This example would benefit from a cause-and-effect hashtag. Conversely, if the paragraph describes an issue like combating the spread of hate speech on social media and proposes monitoring improvements as solutions, it is demonstrating a problem-solution structure.
