Conclusion Among the various models of Delta vacuum cleaners, one cannot accurately predict how effectively a particular model cleans simply by determining how powerful its motor is. ███ ██████████ ██ ████ ██████████ ███████ ██████ ██████████████ ████ ███████ ██████ ██ █████ ██████ ████████ ████████ ████ ███████████ ████████ ███████
Summary
The author concludes that one can’t predict how effectively a Delta vacuum cleans just by determining its motor power. He supports this by saying that the efficiency of dust filtration systems varies greatly, even between models with the same motor power.
Missing Connection
The author’s conclusion is about predicting a vacuum’s cleaning effectiveness, but his premise says nothing about cleaning effectiveness. To get from his premise to his conclusion, the author must assume that the efficiency of a vacuum’s dust filtration system impacts that vacuum’s cleaning effectiveness.
