Manager: Our new computer network, the purpose of which is to increase productivity, can be installed during the day, which would disrupt our employees' work, or else at night, which would entail much higher installation charges. Since saving money is important, we should have the network installed during me day. The manager's argument assumes which one of the following? ["Most of the company's employees would be able to work productively while a daytime installation is in progress.", 'The monetary value of the network equipment would not exceed the cost of having the equipment installed at night.', "Once the network has been installed, most of the company's employees will be able to use it immediately to increase their productivity.", 'The monetary value of any productivity lost during a daytime installation would be less than the difference between daytime and nighttime installation costs.']
