Even though Clovis points, spear points with longitudinal grooves chip

Dear experts
egmat AjiteshArun generis

Can we eliminate choice B on the basis of no subject - verb for 1st IC?

Respect for Experts, they are the saviours

(B) Although named for the New Mexico site where first discovered in 1932, Clovis points are spear points of longitudinal grooves chipped onto their faces and have been found all over North America.

(C) Named for the New Mexico site where they have been first discovered in 1932, Clovis points, spear points of longitudinal grooves chipped onto the faces, have been found all over North America.

(D) Spear points with longitudinal grooves that are chipped onto the faces, Clovis points, even though named for the New Mexico site where first discovered in 1932, but were found all over North America.

I have gone through other answers and have found in them different errors in the given choices, but while solving the question I rejected the incorrect options because of some other reasons 'as well'.

GMATNinja VeritasKarishma mikemcgarry daagh If you can please provide your valuable thoughts on them.
Shouldn't the underlined part say, "where they were first discovered" or at least have a 'comma' before where. Its usage makes more sense in option 'D'
The original sentence specifically says 'onto their faces', in this option that is changed to 'onto the faces'.
Again 'onto the faces' instead of 'onto their faces'

In option A
A. Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, they are named for the New Mexico site where they were first discovered in 1932. Correct. No errors.

Is there any fragment here or are the clauses present here not independent. I am getting confused with comma splice situation??

In option D
D. Spear points with longitudinal grooves that are chipped onto the faces, Clovis points, even though named for the New Mexico site where first discovered in 1932, but were found all over North America.Incorrect.
1. There is only one verb for "Spear points??????. But still the choice is using ???but???. This means there should be another verb here. Absence of this verb leads to fragment error.

What is the verb issue here?? The first phrase has chipped as a verb right and this phrase is referring to Clovis points. Again, are all the clauses independent or is there any issue of fragment here??

(D) Spear points with longitudinal grooves that are chipped onto the faces, Clovis points, even though named for the New Mexico site where first discovered in 1932, but were found all over North America.

Here in option B although is used, it is a subordinating conjunction but there is no clause ,is it enough to eliminate the answer choice here ?

Hi there,

Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been round all over north America ,they are named for the new Mexico site where whey were first discovered in 1932.

The contrast set by the original sentence is that Clovis Points have been found in all over the North America, but they are named for the New Mexico where they were first discovered in 1932. This contrast is correct.

So let’s proceed to the PoE now:

A. Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, they are named for the New Mexico site where they were first discovered in 1932. Correct. No errors.

B. Although named for the New Mexico site where first discovered in 1932, Clovis points are spear points of longitudinal grooves chipped onto their faces and have been found all over North America. Incorrect.
Notice the contrast this choice presents. It says although CPs are named for New Mexico site where…, they are spear points. This is not the intended contrast. The contrast is between where they have been found and for what they have been named. This sentence presents the contrast that says they are named for NM site but they look like this.

C. Named for the New Mexico site where they have been first discovered in 1932, Clovis points, spear points of longitudinal grooves chipped onto the faces, have been found all over North America. Incorrect.

1. Use of present perfect tense “have been discovered” is incorrect to refer to an action that took place in 1932.

2. This sentence does not present any contrast.

D. Spear points with longitudinal grooves that are chipped onto the faces, Clovis points, even though named for the New Mexico site where first discovered in 1932, but were found all over North America.Incorrect.
1. There is only one verb for "Spear points…”. But still the choice is using “but”. This means there should be another verb here. Absence of this verb leads to fragment error.

E. While Clovis points are spear points whose faces have longitudinal grooves chipped into them, they have been found all over North America, and named for the New Mexico site where they have been first discovered in 1932. Incorrect.

1. Per this sentence, the contrast is that CPs are spear points but they have been found all over the North America and are named for the NM site. This certainly is not the intended contrast.

Take Away

1. Understand the context of the sentence very well. Carefully notice the contrasts or comparisons made.

2. Assess if those contrasts or comparisons are logical or not.

3. Once you get the intended logical meaning, do the POE to find out which answer choice conveys the intended meaning in the best way.

Hope this helps.

here named could be participle , In OG 2019 question 722 , it is mention that although should be followed by finite clause with a subject not by a participle
Can you please explain more about when we can eliminate the choice on this basis ?

OG- Although covering the entire planet, Earth has a crust

(A) Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, they are named for the New Mexico site where they were first discovered in 1932.

(B) Although named for the New Mexico site where first discovered in 1932, Clovis points are spear points of longitudinal grooves chipped onto their faces and have been found all over North America.

Compare that to choice (B):

This basically means, "Clovis points ARE spear points of longitudinal grooves chipped ALTHOUGH they are named for the site where they were first discovered."

Think about that for a moment. "Clovis points ARE spear points DESPITE THE FACT that they are named for the site..."? There is no contrast between the NAMING of the Clovis points and what the Clovis points actually ARE. So the use of "although" simply doesn't make any sense.

This is, admittedly, a subtle and tricky point. But that's the GMAT for you: you have to practice thinking really hard about the meaning of these sentences.

Trying to come up with an ever-growing list of rules will prevent you from thinking about meaning -- and, unfortunately, that endless list of "rules" probably won't help you improve your score much.

I hope this helps a bit!

I get the points and explanations given.
So, while presenting a contrast or a comparison between two things needs to be parallel i.e. apple vic-a-vis apple contrast/comparison.

Hence, can I write option B as:
Although named for the New Mexico site where first discovered in 1932, Clovis points, spear points of longitudinal grooves chipped onto their faces, have been found all over North America.

Is that correct.? If not why?

I understand that if it is correct two options would be correct but just trying to be clear.
