QUESTION TEXT: Manager: Our new computer network, the purpose…
QUESTION TYPE: Necessary Assumption
CONCLUSION: The network should be installed during the day.
REASONING: A daytime installation will disrupt workers but save money.
ANALYSIS: A daytime installation will decrease productivity, temporarily. And that costs money. The argument ignores this and makes no attempt to consider the downsides of a daytime installation vs. a nighttime installation.
___________
- If the value of the equipment doesn’t exceed the cost of installing at night, then we should definitely not install during the night. We’d lose money.
- CORRECT. The business loses money by disrupting its workers. It also loses money by paying extra for nighttime installation. The argument assumes the latter costs more, but provides no evidence.
- Time doesn’t matter, per se. It’s the cost in money or productivity that matters.
- It doesn’t matter how long before the network is productive. We’re trying to figure out when to install it. What happens after doesn’t matter.
- This would strengthen the argument, but it isn’t necessary. It could be the installation only takes one hour, but costs $5 million extra to install at night. That might make daytime installation very cheap even if productivity was wrecked during that one hour for 51% of employees.
