Final answer:
Making inferences requires drawing a conclusion from details in the text, and option (d) regarding changing school letting-out times could be supported by context hinting at traffic and safety concerns.
Step-by-step explanation:
The question relates to making inferences based on details provided in a text. To make an informed inference, one must consider multiple details and draw a conclusion that is the most likely and supported by the text. When evaluating the options provided, option (d) can be inferred as it is reasonable to assume that if the city changed the school letting-out time, it could address issues that are hinted by the context, such as congestion or safety concerns that affect children.
This inference might be supported by various details throughout the text, for instance, arguments concerning traffic, safety, or the well-being of students. Without the precise text, it's challenging to determine the exact details, but based on the provided exercise examples, we can understand the process of making a sensible inference.
The information about children spending one-third of their time in school, for example, leads to an understanding of their daily routine rather than making assumptions about truancy.
