Question
In the question below, a passage is given followed by
three statements. You must determine which combination of the statements WEAKENS the argument presented. Argument: A tech company claims that its "Autonomous Delivery Drones" will completely replace traditional courier trucks in metropolitan areas by 2030, drastically reducing urban traffic congestion and lowering delivery costs for retailers. Which of the following statements, if true, would WEAKEN the company's argument? I. Current drone models have limited battery life and require expensive specialized landing pads that most urban retailers cannot yet afford to install. II. Public opinion surveys indicate that residents in high-density areas are concerned about the noise and privacy risks associated with constant drone activity. III. Recent trials in two cities successfully delivered lightweight medical supplies across short distances using these drone prototypes.Solution
The Argument: The company claims drones will completely replace trucks, reduce traffic, and lower costs. Statement I (Weakens): This mirrors your "energy-intensive and expensive" logic. It points out logistical and financial barriers (battery life and infrastructure costs) that make the "complete replacement" of trucks by 2030 highly unlikely and economically unfeasible for now. Statement II (Weakens): This mirrors your "consumer preference" logic. If the public is hostile toward drones due to noise and privacy concerns, regulatory hurdles or low adoption rates will likely prevent them from dominating the market, regardless of the technology's efficiency. Statement III (Neutral): This mirrors your "small batches" logic. While it shows the technology can work (Proof of Concept), a successful trial for "lightweight medical supplies" over "short distances" does not prove that drones can handle the massive, diverse scale of general retail delivery needed to replace trucks.
