Would you agree on these inputs on (C) ?

-- Traditionally most GMAT assumptions are necessary assumptions. (C) seems to go over-board
If you conclude that the text was written no later than 1167, and your only evidence is a diagram, then, yeah, your argument requires that the diagram be accurate.
It's true that we only need one little part of the diagram to be accurate, jabhatta2, but the answer choices aren't granular enough so as to question the accuracy of each part of the diagram separately.
Negation test: if we find out that the diagram does NOT accurately represent the composition of Sviatov's family at the time Sviatovin was written, then the entire logic behind the conclusion (that the text was written no later than 1167) crumbles.

Hi avigutman AnthonyRitz - thank you so much for your inputs.

What both of you said in the posts just above make sense. - the book was definitely written AFTER 1165 (that cannot be disputable) - I did not make that inference. I understand the logic for this now

The only thing questionable is : was the text written PRIOR to 1167

While we are only left with (c) so we have to pick (c) -- however, would you agree on these inputs on (C) ?

-- Traditionally most GMAT assumptions are necessary assumptions. (C) seems to go over-board

Here is why :

(C) is is suggesting two things

(i) mom / dad / brother / sisters /grandmom / grand-dad / grand-mom / great grand mom / great grand-father / children / wives / cousins = EVERYONE IS ALL listed accurately.
(ii) LIVING / Deceased STATUS of EACH ONE is listed accurately as well.

(C) is suggesting both the above bullet points.

However, I think only DAD and the living /deceased status of DAD specifically is necessary for this argument.

If mom / brother / sister /grandmom .... is listed incorrectly and THE LIVING STATUS of mom / brother / sister / grandmom is listed in-accurately as well --- it doesnt hurt the argument.

Thoughts ?

Yeah I'm not convinced that this is the typical necessary assumption question, but even if it was, imagine negating C:

Quote:
the diagram DOES NOT accurately represent[] the composition of Sviatov's family at the time Sviatovin was written

Then I'd say the family tree showing the father alive gives no reason whatsoever to assume that Sviatov's father was actually alive when the book was written. And therefore the conclusion is, if not wrong, at least without any basis in the argument. I'd consider that a good enough basis to pick this answer.

''in the diagram of Sviatov's family that accompanies the text his father, who died in 1167, is identified as still living''

isn't this a premise and we are doubting the premise in C]?

Ah, no, actually, I don't question that at all.

It is undeniably true that "in the diagram... his father... is identified as living" (emphasis added). I don't question what the diagram shows. I question whether the diagram is accurate. These sorts of fine distinctions are the bread and butter of GMAT critical reasoning, so it's important to practice picking out the little wiggle words like "identified" that create such gaps!

The argument in the passage relies on the assumption that:

(C) the diagram accurately represents the composition of Sviatov's family at the time Sviatovin was written.

The argument assumes that the diagram accompanying the text accurately reflects the family composition during the period when Sviatovin was written. If this assumption is false and the diagram is inaccurate or represents a different time period, then the conclusion drawn about the time of Sviatovin's composition would be invalid. Therefore, establishing the accuracy of the diagram is crucial for determining the timeframe of Sviatovin's writing based on the information provided.

I think option B is incorrect because of the word used here as possible, in my reasoning if author explicited as much correct information as possible means author may used the events correctly but can choose random dates, so B is not must be true

The answer here is not (B) though the word 'possible' doesn't have much role to play.

the author of Sviatovin intended it to provide as accurate a report about Prince Sviatov's exploits as possible

The argument is all about the diagram and his father shown in it. There are no question marks on the reports on Sviatovin's exploits. So (B) is irrelevant.
Also, "as accurate as possible" only means using as much information as the author could find. When we write about a person's life, only the person himself knows the whole truth. We can write about the publicly known facts and whatever the person tells us. So we can write it as accurately as possible if we duplicate the known facts honestly. We may not be able to write more accurately than that.

Here is why (C) is correct: https://gmatclub.com/forum/sviatovin-is ... l#p1158743

The passage says that in the family diagram Sviatov???s father is ???identified as still living.??? Why, then, does the argument still need to assume that the diagram represents the family as it existed at the time Sviatovin was written? If the diagram labels the father as alive, and the text even includes material attributed to him, does that not already imply that the text was written before his death?

My few words -

Sviatovin is a medieval Moringian text whose author and exact date of composition are unknown. However, the events in the life of Prince Sviatov that the text describes occurred in 1165, and in the diagram of Sviatov's family that accompanies the text his father, who died in 1167, is identified as still living. Thus Sviatovin must have been written between 1165 and 1167, assuming that _____________ .

The key point is that being identified as living does not by itself fix the end time of writing.

Even though Sviatov’s father is identified as still living in the diagram, the text could still have been written much later, for example in 1200. The diagram could simply be describing the family as it existed during the events being narrated (around 1165), when the father was indeed alive, even if the author wrote the text decades afterward. In that case, the father would correctly appear as living, but the text would not have been written before 1167.

Therefore, to conclude that Sviatovin must have been written between 1165 and 1167, we need an assumption that rules out the possibility that the diagram reflects an earlier historical moment rather than the time of writing. In other words, we need an assumption that the text was not written after 1167.

This is why choices B and C may initially seem close, but only one actually does the needed logical work.

Choice (B) says that the author intended to provide as accurate a report as possible about Prince Sviatov’s exploits. However, “exploits” refers to the actions, campaigns, routes taken, or strategies used by the prince. Accuracy about exploits has nothing to do with dating the text. The author could be perfectly accurate about events and still write long after 1167. This option does not constrain the timeline at all.

Choice (C) says that the diagram accurately represents the composition of Sviatov’s family at the time Sviatovin was written. The word “accurately” by itself is not the key issue. The crucial phrase is “at the time Sviatovin was written.” This assumption directly links the diagram to the time of writing. Once that link is established, the fact that the father is shown as alive means the text must have been written before his death in 1167. That is exactly what the conclusion requires.
