Passage Summary: The tax office said they would get tough on companies, but they haven't completed any audits all year, so they clearly aren't doing what they promised.

Conclusion: The government's tax agency has failed to carry out its promised crackdown on corporate tax law violations.

Reasoning: Audits are the main way to catch these violations, and the agency has not finished a single corporate audit in the year since the crackdown was announced.

Analysis: The argument assumes that 'completed audits' is the only metric for a 'crackdown.' To weaken this, we need to find evidence that the agency is actually working hard behind the scenes. Perhaps they have thousands of audits currently in progress that are much more thorough than in previous years, or maybe they've switched to a different enforcement method entirely. Look for an answer that suggests the lack of *completed* audits doesn't necessarily mean a lack of *activity* or *intent* to enforce the law.
