Passage Summary: A travel company that usually does flights is suddenly hiring bus experts; since their current fans still like flying, they must be looking for a whole new crowd.

Conclusion: Travaillier Corporation is attempting to expand its business by targeting a new demographic of customers.

Reasoning: The company is investing in bus tour expertise and infrastructure despite their current customer base still preferring air travel.

Analysis: To weaken this argument, we need to find another reason why a flight-focused company would suddenly care about buses besides 'getting new customers.' The argument assumes that if the current customers haven't changed their preference for air travel, the bus investment cannot be for them. Look for an answer that suggests the bus activity serves the current air-travel-loving clientele in some way, such as providing airport transfers or replacing short-haul flight segments.
