Original sentence reads best here. Although I would recommend a space between 35 and years to make it a perfect.

C 50%

Two past perfects in the same sentence don`t seem to make much sense.

What is the structure of this sentence?

yeah... weird question... sounded like Brazil migrated to TEXAS but BRASIL can be easily eliminated

[Less than 35 years] after the release of African honeybees outside Sao Paulo, their (honeybees's) descendants, [popularly known as killer bees,]had migrated as far north as southern texas.

Will go with A.

Two past perfect is not required. This is something that GMAT tests a lot along with modifiers.

how is it correct to use past perfect in a sentence with only one clause?

i would choose D, if it didnot have "when".

I think the answer is A.

D & E don't appear to make any sense, and are extremely wordy.

I had to read B & C over and over again to make a decision, but I don't believe that 'In less than' properly relates to the remainder of the sentence.

also to me the answear should be A seems the most concrete one C has past perfect problems...

A for me.

B: since releasing - unnecessary tense change
C: had been, wordier than A
D: when is incorrect
E: too wordy, and then incorrect

in case you want my opinion, here it is:

I think the problem with D is that it's unclear exactly what took less than 35 years from release of honeybees... What is IT referring to?

It took X years from the release... what took... ok Years... but "YEARS FROM THE RELEASE" doesn't make sense... "IT TOOK X YEARS to release" but not from the noun... years can't be taken from release...

so to put the sentence with D together...

It took less than 35 years from the release of African honeybees outside Sao Paulo, their descendants, [popularly known as killer bees,] had migrated as far north as southern texas.

it is saying "It took X years their descendants had migrated to texas"... does this make sense? not at all... IMO I can't see what was taken... X years or their descendants... but then, descendands migrated to texas...

I am sorry I don't know the grammar language to describe the problem, but clearly there is a problem with the logical structure.

thanks u2.

but i am not pleading for D. my question was/is "how can you use a Past perfect in a single clause sentence in which there is no sequence of tenses?" to use past perfect, imo, we need at least two past actions one happened earlier than the other.

I am absolutely agree with Professor
Can somebody explain the use of Past perfect here?
When I see Past Perfect in the sentence, I automatically look for an option with another Past Simple Tense.
But In A no Past Simple is given!

Professor and caas are making an excellent point.
In past perfect as well as in Present perfect, we have to refer to a point in the past in order to express the contiunuity of the action.

Here we are in the past perfect. The first things to do should be to seek for an earlier point that is expressed most of the time as a precedent action properly modified by the tense of the verb or that is implied in the meaning of the clause. Here it is implied.

Had + Verb => signals that the action happenned first in the past.

so will should seek for the reference point of "HAD merged" that is in that case "Less than 35 years"

Thus we know that " Bees Had migrated..." before the complete time span of 35 years.

Considering answers C it is wordier and not logical, 2 past perfect in the same sentence? "had been released" becomes the reference point and makes no sense with the tense of the whole sentence.

I will go for A
