But for B it says “Neanderthals had A vocal cord”. Have can they have ONE vocal chord for a plural “Neanderthals”?

If we say, Apple iPhones have a good camera that is similar to the camera found in Samsung phones. We are not saying that all the iPhones in the world have one camera. We are comparing one aspect of iPhones, i.e., the camera, with a camera of Samsung phones.

Likewise, here we are comparing one aspect of Neantherdals, i.e., vocal tracts, with a vocal tract of apes. We are not saying that all Neantherdals have one vocal tract. I hope it helps. (I know Apple or Samsung lovers may not like this comparison :) But just bear with me for the sake of clarity to our friend @donu)

Hi GMATNinja - how is the usage of 'had' correct in options A and B? Considering there are no two past events that need to be differentiated.

Hi GMATNinja - how is the usage of 'had' correct in options A and B? Considering there are no two past events that need to be differentiated.
The word "had" can be used as a helping verb to create a past perfect verb form, but it can also just be a verb on its own. For example:

    "Tim had a Porsche, until he sold it to pay for daycare."

Here, "had" is just a simple past tense verb.

The same is true in (A) and (B) -- "had" is just the simple past form of the verb "to have".

  • Present singular: "The Neanderthal has a vocal tract."
  • Present plural: "Neanderthals have a vocal tract"
  • Simple past singular: "The Neanderthal had a vocal tract."
  • Simple past plural: "Neanderthals had a vocal tract."

I hope that helps!
