from 1900 B.C.
E. The text from 1900 B.C. describes itself as a comprehensive list of all the constellations.


Is it E?


We need to strengthen the idea that "the Egyptians had not yet named most of their later constellations, ie after 1900"
Support for this is "historians have found text in 1990 that names only 10"
What if more existed that named the remaing constellations and historians just didn't find any? I think this is take care by E....
What does the source say? and What is the source?

A. The ten constellations named in the text from 1900 B.C. were among those named in the tablets dating after 1300 B.C.
Weakens

B. Several Egyptians texts dating between 1900 and 1300 B.C. list more than ten constellations.
We are only interested in things that in 1900 not in between

C. Historians know of no Egyptians texts from 1900 B.C. that claim to be a comprehensive list of constellations.
Oppostie of what we want

D. Another Egyptians text dating from before 1900 B.C. mentions constellations other than those mentioned in the text
from 1900 B.C.
again before 1900, not interested.

E. The text from 1900 B.C. describes itself as a comprehensive list of all the constellations.
OK.

Cheers


I guess the answer is A

We need to strengthen the fact that "Some historians have inferred from this that in 1900 B.C., the Egyptians had
not yet named most of their later constellations. "

The statement means that constellations were known but the naming was not done.
A states the same thing.

OA is ...
If indeed 1900BC text acknowledged that the text is a COMPREHENSIVE LIST OF ALL constellations, how does it support
historians' position that the same 1900BC list is NOT complete.

The argument is that Egyptians knew about 40 but had not named most of the constellations. Only C supports this. Basically if none of the text claims to be comprehensive list it shows that text had listed only some of those.
C it is.

to put in a simpler terms

absence of proof or something doesn't mean the things itself does not exist. so ans choice E close this gap saying what ever text we have found in the complete text there is, confirming the assertion that these 10 constellations are only 10 Egyptians had named.

Re: Many Egyptian tablets dating after 1300 B.C. list more than [#permalink]
Jp27 u just on spot.

prem1: In 1300BC: text lists > 40 constns
Prem2: In 1900BC: text mentions only 10 constns

Concl: Historians assert that most of the constns in 1900BC are yet to be named.

What additional premise, info, or evidence will make us believe more in the historians?

Supposing it is TRUE that 1900BC text is COMPLETE.. Does it make us believe more that there are still
more constellations to be named?

Consider:
prem1: In 1300BC: > 40 constns
Prem2: In 1900BC only 10 constns; Also, says this text is a complete list of all constns
ok, if the list is TRULY COMPLETE, then we expect more listings since we are aware there are >40

What is the source of this question? if the OA is E then it is not correct.

Question says, text in 1300 BC lists more than 40 constellations but in 1900BC lists only 10. The reason is given that egyptian had not named other constellations. That is - they knew about other constellations but had not named them. Ans C correctly idenfiies a case in which none of the text claimed to be a comprehensive lists, because they knew there are more constellations just that names are not ready and so can not be put in texts.

conclusion is "Some historians have inferred from this that in 1900 B.C., the Egyptians had not yet named most of their later constellations"
historians have inferred this based on the text from 1900 B.C.
Option C - Historians know of no Egyptians texts from 1900 B.C. that claim to be a comprehensive list of constellations.

if Historians know that these texts are not complete then they cant infer / conclude anything based on incomplete texts/evidence.

Re: Many Egyptian tablets dating after 1300 B.C. list more than [#permalink]
Just have a look at this sentence..
"Some historians have inferred from this that in 1900 B.C., the Egyptians had not yet named most of their later constellations."

Notice the word "later" and its importance as explained below:

A. The ten constellations named in the text from 1900 B.C. were among those named in the tablets dating after 1300 B.C.
Correct: This option actually strengthens the historians reasoning. Refer the conclusion "the Egyptians had
not yet named most of their later constellations" The conclusion clearly states that most of "later" constellations were not named. The word "later" indicates that there are some constellations after 10 constellations, which means that these 10 constellation must have been named in 1300 BC. So this supports the argument that most of "later" constellations were not named.


B. Several Egyptians texts dating between 1900 and 1300 B.C. list more than ten constellations.
Incorrect. even if this lists more than 10 constellations, this doesn't support whether "later" that 10 were not named.

C. Historians know of no Egyptians texts from 1900 B.C. that claim to be a comprehensive list of constellations.
Incorrect. this doesn't support whether "later" that 10 were not named

D. Another Egyptians text dating from before 1900 B.C. mentions constellations other than those mentioned in the text from 1900 B.C.
Incorrect. this doesn't support whether "later" that 10 were not named

E. The text from 1900 B.C. describes itself as a comprehensive list of all the constellations.
Incorrect. this doesn't support whether "later" that 10 were not named

Answer: A

Hope this clarifies.

Which of the following, if true, would most strengthen the historians’ reasoning?
A. The ten constellations named in the text from 1900 B.C. were among those named in the tablets dating after 1300 B.C. HOW DO WE KNOW THESE WERE NOT COMPREHENSIVE ? INCORRECT..

C. Historians know of no Egyptians texts from 1900 B.C. that claim to be a comprehensive list of constellations. CORRECT.... COULD NOT BE COMPREHENSIVE.... SUPPORTS A BIT.....
D. Another Egyptians text dating from before 1900 B.C. mentions constellations other than those mentioned in the text

WEAKENS....CONFIRMS THEY WERE COMPREHENSIVE ? INCORRECT..........
