This is a sufficient assumption question, as the question stem asks: Which one of the following is an assumption that would permit the conclusion above to be properly drawn?

We’re told that every photo must in some ways be true - that stuff in between the commas is science stuff that basically means that because the light of what we capture hits the film. The next sentence begins with a “but” which indicates a potential pivot; the argument goes on to say because of things like Photoshop or angles/posing (cue social media) it doesn’t show the whole trust and is false. Our conclusion comes in and says nothing can ever be proven with photos. First, “nothing” is very strong. Second, being false and proving something are two different, albeit related, ideas. What if you can prove something to be false with an altered photograph by comparing it to what’s actually the case? Let’s link these ideas up with a rule: “If a photograph can be altered to prevent showing the whole truth and is therefore false, then nothing can be proven with it.”

Correct Answer Choice (A) This is correct because it links up our premises with the conclusion and forced our conclusion to be true. While it’s not a perfect paraphrase of our rule, it conveys the same thing.

Answer Choice (B) We’re told that photographs cannot express the whole truth. What does knowing the whole truth have to do with our argument? With our premises and this answer, we cannot force the conclusion.

Answer Choice (C) Being able to figure out whether or not a photograph is truthful does not help push out our conclusion; we still won’t know what is true or false, and this answer choice does not bridge the gap between something being false and figuring out what is not provable.

Answer Choice (D) This does not help justify that nothing can be proven with a photograph. The answer choice adds more information about finding out the truth of the scene of the photograph and then determining what we can use to photograph as evidence. This is more information unrelated to justifying our conclusion.

Answer Choice (E) This would weaken our argument - this is out.
