Quote:
(E) The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.
Based on the evidence, we know that the bone flute could have been used to play four of the notes in the diatonic scale. But does that necessarily mean it was used to play the ENTIRE diatonic scale? Maybe it was only used to play 4 or 5 notes? In that case, the full diatonic scale may not have been developed and used until thousands of years later.

Choice (E) does not PROVE that the flute had all 7 notes. However, (E) gives us evidence that the flute could have easily been long enough to play a full diatonic scale. Sure, the Neanderthals may not have used the full length of the leg bone for the instrument. However, with choice (E), we are now better off than we were given the information in the passage.

(E) definitely supports the hypothesis and is the best option.

hey GMATNinja
I have a problem with E
it doesn't tell us whether it was found thousands of years before.

It doesn't particularly matter when the flute was found. We know that it was excavated at a Neanderthal campsite, but the argument doesn't specify when that excavation took place. Knowing that information wouldn't really impact the argument that the diatonic scale was in use thousands of years before the Renaissance.

If you're talking about when the flute was made, then sure! You've identified a small gap in the argument. The author fails to PROVE that the flute excavated at the Neaderthal site is thousands of years old. So, it would strengthen the argument to fill in that gap.

Unfortunately, there are tons of similar gaps that you could think of, and there's absolutely no guarantee that the correct answer choice addresses your particular concern. For example, I could say that the author fails to demonstrate that animals didn't chew the holes in the bone. There's another gap that (E) doesn't address!

So, thinking of how you would strengthen the argument before looking at the answer choices isn't necessarily the best way to go through a CR question. Instead, just evaluate the options in front of you. (E) strengthens the argument, even if it doesn't exactly fill the hole that you've found in the passage. That's enough to make to make (E) the correct answer.

I hope that helps!

Thanks GMATNinja for your rich explanation!

Answer E specifies that the bone was created out of "cave-bear leg".

This info (1) doesn't appear in the original text (2) doesn't contribute to E's essential argument.

This was a clear signal for me that E is not the right choice. Why is this reasoning wrong?

Information that supports a hypothesis doesn't need to appear in the original passage. It just needs to increase the likelihood that the hypothesis is true. In fact, outside information can very often strengthen a hypothesis.

So does (E) strengthen our hypothesis?

Well, if the cave-bear leg bone were too short, it may not have been able to contain the full diatonic scale. Since (E) confirms that the bone was "long enough to make a flute capable of playing a complete diatonic scale," it supports the idea that the bone was used to play this scale. This in turn supports the hypothesis that the diatonic scale was developed thousands of years ago, since the bone fragment was found at a Neanderthal campsite.

Put another way: although the current fragment is too short to play the diatonic scale, (E) says that the original bone was long enough to play the full diatonic scale. This supports the idea that the scale was developed thousands of years ago, when the bone flute was likely made. Since (E) supports the hypothesis, it's correct.

I hope that helps!

avigutman Can you please explain why B is wrong though I read the above discussion but I am still not crystal clear why that is wrong ?
According to B the bone is the first known musical instrument to use diatonic scale hence it proves the conclusion. The way B is written -before the flute, there was no instrument that used diatonic scale- seems to state that the flute was the instrument "that used diatonic scale".

Other than my sister there was nooone that i could count on- implies i could count on my sister. I ve used same logic for above interpretation. egmat GMATNinja GMATGuruNY

The implication that I highlighted in the quote is incorrect, Elite097.
Here's (B):
Quote:
No musical instrument that is known to have used a diatonic scale is of an earlier date than the flute found at the Neanderthal campsite.
This is a comparison of dates: we have the date of the fragment of a bone flute. We are told that prior to that date there's no evidence of something. That's all (B) says.
Your analogy about your sister is not analogous. That sentence is about who you can or cannot count on - it's not a comparison of dates.

The fragment of the flute was found at a Neanderthal campsite. Neanderthals haven't been around for a few thousand years. So, presumably, if the Neanderthals were using this flute to play music in the diatonic scale, then this scale has been around for a few thousand years, right?

That's what (E) is giving us evidence for. If this Neanderthal-built flute were long enough to play the diatonic scale, it increases the likelihood that the Neanderthals were, in fact, playing this scale. If the Neanderthals, who haven't been around for thousands of years, were playing this scale, it means the scale is thousands of years old. Simple as that.

I hope that clears things up!

I had a particularly hard time with this question, so I made a crude visual aid. "Fragment of a bone flute" is easy to miss.

(If anyone were interested, the real thing is called the Divje Babe flute).

Answer choice B raises significant confusion. At the time of making this post, 23% of people had selected B as their answer. The main confusion seems to stem from what the statement even means. I'll try to address that in this post.

A common interpretation is:

The flute that was found at the neanderthal campsite site is the oldest musical instrument that is known to have used a diatonic scale.

This interpretation is wrong.


To explain, let me start with a simplistic example.

Say there are 10 animals standing in front of us.

We know that 9 of them are dogs. We don’t know yet what the species of the 10th animal is.

If I now tell you that:

None of the 9 dogs is older than the 10th animal.

Does that make the 10th animal a dog?
Does that mean that the 10th animal is the oldest DOG among the 10?

No.

It just means that the 10th animal is the oldest among the 10 animals. We still don’t learn the species of the animal.


Another example:

No musical instrument is older than that yellow stick.

Can we infer that the yellow stick is a musical instrument?
No.

The yellow stick is older than all musical instruments. But we learn nothing about whether it is a musical instrument or not.



The same way,

Answer choice B just tells us that no musical instrument (of a particular kind) is older than the flute that was found at the campsite.

That means that the found flute is older than any 'musical instrument that is known to have used a diatonic scale'.
However, it doesn't imply that the found flute is the oldest 'musical instrument that used a diatonic scale'.
In fact, it doesn’t even imply that the found flute is a 'musical instrument that used a diatonic scale'.

One reason for the confusion between (B) and (E) could be that people incorrectly paraphrased the passage (just as I did). It never mentions that the bone is sufficient to play the diatonic scale. The argument only suggests that the bone might be likely to play it as it could play some parts of it.

If the argument had stated that the bone could completely play the diatonic scale, then (B) would have served as a strengthener.

Hope this helps someone.

A bone flute excavated at Neanderthal campsite had 4 holes perfectly spaced to play 3-6 notes of modern day diatonic scale

Hence,
The scale was developed before the westerners found it.

(A) Bone flutes were probably the only musical instrument made by Neanderthals.
Okay but how we can establish on the diatonic scale being before westerners - what if the 4 dots were just a fluke?

(B) No musical instrument that is known to have used a diatonic scale is of an earlier date than the flute found at the Neanderthal campsite.
No instrument which could play the scale is of a previous date than this flute. This just confirms lets say flute is 2 million yrs ago dated - no instrument more than 2 yrs old can play the D scale. But we cannot jump and say HEY THAT MUST BE FLUTE WAS USED TO PLAY D SCALE! It is just a cognitive bias to fill the gap. Remember, Our only proof is 4 holes - what if the 4 dots were just a fluke without knowledge of D scale or using the scale?

(C) The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears.
Ok great we know the material of bone? How does that help to prove our conclusion?

(D) Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.
Ok great. So?

(E) The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.­
If the bone was small enough and could not have used to make all holes - we couldnt be sure that the 7 notes which make up the D scale would even be possible hence shaking the conclusion.
marine
The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians.

Which of the following, if true, most strongly supports the hypothesis?

(A) Bone flutes were probably the only musical instrument made by Neanderthals.

(B) No musical instrument that is known to have used a diatonic scale is of an earlier date than the flute found at the Neanderthal campsite.

(C) The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears.

(D) Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.

(E) The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.­
