Advertisement: Avian Oculars are the newest in binocular technology fo

OFFICIAL EXPLANATION

The advertisement discusses the merits of Avian Oculars, explaining that they are reasonably priced and contain several popular features. The advertisement concludes, however, by encouraging readers to use Avian Oculars in order to see some of the world’s rarest bird species. A proper assumption must reasonably connect these diverse ideas.

(A) The argument states that Avian Oculars are lightweight, but makes no direct comparison to traditional binoculars.

(B) Although the advertisement is geared toward bird watchers, nothing indicates that Avian Oculars should be used only by bird watchers. Even if Avian Oculars were used by individuals other than bird watchers, no information in the advertisement would be undermined.

(C) CORRECT. The conclusion of the advertisement is that, by using Avian Oculars, the reader will see some of the world’s rarest bird species on his or her next bird watching trip. In order for this to be true, the reader would have to have access to these rare bird species. Even the best bird watching technology would prove useless to view a particular species of bird if the species were not present.

(D) This choice is true, but it is not an assumption. Remember, an assumption is an unstated piece of information that ties a conclusion to its premises. This particular answer choice is simply a stated premise from the second sentence of the argument.

(E) This argument presents one specific product, Avian Oculars, which is specifically designed with birding enthusiasts in mind. From this information, we cannot assume that birding enthusiasts themselves determined the specifications of Avian Oculars, nor can we make any assumptions about who determines the specifications of other products.
