Advertisement: Avian Oculars are the newest in binocular technology for the professional bird watcher. For a price
comparable to that of traditional binoculars, Avian Oculars are specially designed with the features demanded by
birding enthusiasts: they are lightweight, compact and extremely durable. So, use Avian Oculars on your next bird
watching excursion, and see some of the world’s rarest species in all of their beautiful plumage. Which of the
following is an assumption on which the author of the advertisement relies?
• Avian Oculars weigh less than traditional binoculars.
• Avian Oculars should be used only by bird watchers.
• The reader will travel through the habitats of rare species during his or her next bird watching trip.
• Avian Oculars are similar in cost to traditional binoculars.
• Birding enthusiasts often determine the specifications of new products.

I think its C.
The conclusion says "take Avian oculars on your next trip" directed towards the readers
Negate option C and your conclusion falls apart.

A - We can't deduce the comparison based on 'light weight'.
B - Too extreme. 'Only' bothers me.
C - Very close answer. However, I am not convinced there is a reason to believe the next trip would be through habitats of rare species.
D - CORRECT. Substitute similar with comparable, and the statement is given in premise.
E - Out of scope.

What is the OA?

I will also go with C.

D is incorrect because it is stated in the argument: Assumptions are unstated premises.

It might be more difficult, in this question, to identify the 'conclusion' since the text is that of an advertisement, and not of an argument. But we do have a sentence beginning with the word 'So...', and what follows is the conclusion: if you take the binoculars "on your next bird watching excursion", you will "see some of the world’s rarest species". Well clearly that's not necessarily going to be true: it's only true if the birdwatcher goes to a location containing rare species, so C is a necessary assumption.

+1 C

The author is assuming that the reader wil find rare bird species in his next trip:

"...and see some of the world’s rarest species in all of their beautiful plumage".

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.

choice c - if you negate it, advertisement breaks - if you say the reader will not travel to the rare habitats, then how can he see those rare species

no matter you have the right tool, until you are not at the right spot, you won't see the damn thing

If you are not in Antartica, don't expect to see the penguins in Texas jungle
The reader will travel through the habitats of rare species during his or her next bird watching trip.

advertisement - So, use Avian Oculars on your next bird
watching excursion, and see some of the world’s rarest species in all of their beautiful plumage.

C. Not saying this question is easy, in fact the answer choices are so strange that it might make the question harder but C is the only option that has any connection to the prompt.

The other options are assumptions based off the prompt and not an assumption the prompt makes. If that makes sense at all.

I chose D although I now know why it is incorrect (assumption needs to be "unstate" premise - D is stated in the argument).
I have not seen this error in any OG CR questions though.

Could someone confirm if there is an example of OG CR questions that list premises as options in assumption questions?
