Newsletter: A condominium generally offers more value for its cost than an individual house because of economies of scale.The homeowners in a condominium association can collectively buy products and services that they could not afford on their own. And since a professional management company handles maintenance of common areas, condominium owners spend less time and money on maintenance than individual homeowners do.

The two portions in boldface play which of the following roles in the newsletter’s argument?

A. The first is the argument’s main conclusion; the second is another conclusion supporting the first.
B. The first is a premise, for which no evidence is provided; the second is the argument’s only conclusion.
C. The first is a conclusion supporting the second; the second is the argument’s main conclusion.
D. The first is the argument’s only conclusion; the second is a premise, for which no evidence is provided.
E. Both are premises, for which no evidence is provided, and both support the argument’s only conclusion.

My Ques: how is boldface 1 a conclusion? Isnt it a premise.
