PrepTest 143 - Section 4 - Question 11

Show summary

A development company has proposed building an airport near the city of Dalton. ██ ███ ████████ ██ ████████ █████████ █████ ███ █████████ ███ ███████ ████ ██ ██████ ████████ ██ ██ ████████ ████ █ ████████ ██ ████████ █████████ █████ █████ ███ █████████ ███ ████ ██ ████ ███████ ████ ███ ███████ █████ ██████ █████ █████████ █████ ██ ██ ████████ ████ ███ ███████ ████ ██ ██████

Summarize Argument

The author concludes that it’s unlikely the airport will be built. This is based on the following:

If most of Dalton’s residents favor the proposal, the airport will be built.

It’s unlikely most of Dalton’s residents would favor the proposal. (This is a subsidiary conclusion based on the fact that most residents believe the airport would create noise problems.)

Identify and Describe Flaw

The author confuses a sufficient condition with a necessary condition. Although most of Dalton’s residents’ favoring the proposal is sufficient for the airport to be built, that doesn’t mean it’s necessary. It’s possible for the airport to be built even if most residents don’t favor the proposal.
