Solution

Sentence Analysis

The sentence presents a contrast. The contrast is that:

  • Even though Clovis points have been found all over North America
  • They are named for a specific site i.e. New Mexico (where they were first discovered in 1932)

Using a Noun+Noun modifier (also called Absolute Phrase), the sentence also provides additional information about Clovis Points. These are spear points with longitudinal grooves chipped onto their faces.

As is, everything is fine with the sentence. There is no error in the original sentence.

Option Analysis

(A) Correct.

(B) Incorrect. For the following reasons:

  1. This option presents an illogical contrast. The contrast presented is that although Clovis points are named for the New Mexico site, they are spear points. Clearly, the contrast doesn’t make sense. The fact they are spear points bears no contrast to the fact that they are named for a particular site. Please note that this is a meaning error. If you are not sincerely trying to understand the meaning of the sentence, you’ll most likely miss the error.
  2. In “where first discovered”, it is not clear what was first discovered. It should have been “where they are first discovered”.
  3. The preposition ‘of’ in “spear points of longitudinal grooves” is incorrect. Spear points are not OF grooves.

(C) Incorrect. For the following reasons:

  1. Incorrect verb “have been discovered”. We do not use present perfect for an event completed in a specific time in the past. We need to use simple past tense “were discovered”.
  2. The sentence now doesn’t present any contrast. Thus, the original meaning, which was logical, has been changed.
  3. The preposition ‘of’ in “spear points of longitudinal grooves” is incorrect. Spear points are not OF grooves.

(D) Incorrect. For the following reasons:

  1. There is no main verb.
  2. In “where first discovered”, it is not clear what was first discovered. It should have been “where they are first discovered”.
  3. The use of two contrast words “even though” and “but” not only is redundant but also distorts the meaning of the sentence.
  4. The use of simple past “were found all over North America” changes the meaning from the original sentence, in which present perfect has been used.

(E) Incorrect. For the following reasons:

  1. The contrast is illogical. The contrast is that while Clovis points are spear points, they have been found all over North America!
  2. The use of present perfect “have been first discovered” is incorrect. We do not use present perfect for an event completed in a specific time in the past. We need to use simple past tense “were discovered”.
