Why do we consider supposedly as adverb because it ends with "-ly" ??
Can somebody please clarify?

Hello PureReason,

I am not sure if your doubt still persists. Here is the explanation nonetheless. :-)


You are correct in saying that the word supposedly is an adverb because it ends with "ly".

Hope this helps. :-)
Thanks.

Let's begin with understanding the meaning of the sentence:

Carbon-14 dating reveals that the megalithic monuments in Brittany are nearly 2,000 years as old as any of their supposed Mediterranean predecessors.

The sentence says that carbon-14 dating shows something. Something = The megalithic monuments in Brittany are very old. They are some 2,000 years as old as any of their so called Mediterranean predecessors.

Now, it does not make sense to say that A is 2,000 years as old as B. On this basis, choices A, C, and E can be rejected.

Choice D can be rejected for the incorrect use of adverb supposedly to modify the noun predecessors.

Hence, Choice B is the correct answer.


Hope this helps. :-)
Thanks.

Carbon-14 dating reveals that the megalithic monuments in Brittany are nearly 2,000 years as old as any of their supposed Mediterranean predecessors.

(A) as old as any of their supposed
(B) older than any of their supposed
(C) as old as their supposed
(D) older than any of their supposedly
(E) as old as their supposedly

I was between option B and D.
As Mediterranean is adjective, which is modifying noun predecessors so don't we need adverb=supposedly to modify Mediterranean predecessors.

Adverb Adjective Noun.

I got this one wrong. The worst part is I knew what was going on - that supposedly modifies Mediterranean and supposed modifies predecessors. The reason I picked "D" i because I thought it's almost established that it is close to 2000 years old. So, there is no reason to doubt that the monuments are predecessors. Whether they are Mediterranean are not, well, that might be in question.

The only explanation I can give myself is that my reasoning would probably differ from the original statement and that if the meaning in the original statement isn't wrong, I shouldn't be changing it. But I can't help thinking about why my logic was incorrect in that case. Could you please help?

Very nice work, Gagoosh! I'll add my two cents, just in case it's helpful to somebody.

There's a pervasive myth that it's unacceptable to alter the meaning presented in choice A. This isn't true. The original sentence is one of five options, all on equal footing. If A is illogical or unclear, we want to change the meaning.

It might be helpful to think of "supposed" in this instance as meaning "incorrectly thought to be." Here's a silly example, "I thought that my friend Alan cut hair for a living, but after my haircut left me looking like an extra from The Walking Dead, I realized that this supposed professional was nothing but an incompetent amateur." "Supposed" basically means that I thought my friend was a professional, but, in fact, he was not.

Same thing in the SC above. The other artifacts were believed to be predecessors, but the dating of the megalithic monuments revealed that they were not.

I hope that helps!

Supposedly can modify mediterranean, which is an adjective here. So it just a matter of identifying whether the ancestor is supposedly mediterranean or the ancestor might not be the real ancestor. I don't see the stimulus is preferring either one of this over the other. Can someone please explain more throughly?

The whole "Carbon-14 dating" and "2,000 years older" bit supports the supposed predecessors call (and not the supposedly Mediterranean call).

Carbon-14 dating reveals that the "predecessors" of the Brittany monuments are not actually the predecessors of the Brittany monuments, as the Brittany monuments are ~2, 000 years older than their supposed predecessors.

Carbon-14 dating reveals that the megalithic monuments in Brittany are nearly 2,000 years as old as their supposed Mediterranean predecessors.

Which of the above two sentences is correct and why?

The development of carbon-14 dating caused the complete collapse of the dif­fusionist view. It was soon learned that the megalithic monuments in several ar­eas of Europe were nearly 2,000 years older than any of their supposed Medi­terranean predecessors. Some of the ear­liest of them, in Brittany, could be dated back to 4500 B.C. There could no longer be any doubt that the monuments, the earliest stone structures still standing anywhere in the world, were of local Eu­ropean origin.

Official Explanation

Diction; Grammatical construction

The sentence suggests that, based on carbon-14 dating evidence, the megalithic monuments in Brittany are 2,000 years older than certain other monuments previously believed to predate them.

The construction 2,000 years as old as . . . fails to convey this age difference; the sentences using this construction are nonsensical and can be firmly eliminated as possibilities.

A. This choice uses the nonsensical construction 2,000 years as old as.
B. Correct. This choice uses the correct construction older than and correctly uses the adjective supposed to modify the noun predecessors.
C. This choice uses the nonsensical construction 2,000 years as old as.
D. This choice uses the correct construction older than. However, it incorrectly uses the adverb supposedly to modify the adjective Mediterranean rather than using supposed as an adjective modifying predecessors.
E. This choice uses the nonsensical construction 2,000 years as old as. Furthermore, it incorrectly uses the adverb supposedly to modify the adjective Mediterranean rather than using supposed as an adjective modifying predecessors.

The correct answer is B.
