Passage Summary: The law says car factories must be 'Class B,' and 'Class B' factories aren't allowed to delay inspections, so car factories can't delay inspections.

Conclusion: Automobile factories are not permitted to postpone their safety inspections under the Factory Safety Act.

Reasoning: The Act requires all automobile factories to be registered as Class B, and it also states that no Class B factory can postpone its inspections.

Analysis: The argument uses a deductive structure to reach its conclusion. It identifies a specific group (automobile factories) and notes that they must meet a certain condition (Class B status). It then identifies a requirement for that status (punctual inspections). By linking these two rules, the author demonstrates that the requirement for the subgroup is a necessary consequence of the broader regulations. To identify the method of reasoning, look for a description of how the author applies a general rule to a specific case through an intermediate requirement.
