This question is testing MODIFIERS and MEANING.
Long overshadowed by the Maya and Aztec civilizations, historians are now exploring the more ancient Olmec culture for the legacy it had for succeeding Mesoamerican societies.
(A) historians are now exploring the more ancient Olmec culture for the legacy it had for succeeding Mesoamerican societies
(B) historians’ exploration is now of the more ancient Olmec culture's legacy to the Mesoamerican societies succeeding them
(C) the legacy of the more ancient Olmec culture to the Mesoamerican societies that succeeded them is what historians are now exploring
(D) the more ancient Olmec culture is now being explored by historians for its legacy to succeeding Mesoamerican societies
(E) the Olmec culture is more ancient and had a legacy to succeeding Mesoamerican societies that historians are now exploring
Whenever a sentence begins with a participial modifier such as "Long overshadowed by the Maya and Aztec civilizations...", that must be followed by the SUBJECT being modified. The thing long overshadowed by other civilizations is the Olmec civilization, not historians.
(A) historians are now exploring the more ancient Olmec culture for the legacy it had for succeeding Mesoamerican societies
- incorrect subject. This implies that historians are being overshadowed.
(B) historians’ exploration is now of the more ancient Olmec culture's legacy to the Mesoamerican societies succeeding them
- incorrect subject. This implies that historians' exploration is being overshadowed.
(C) the legacy of the more ancient Olmec culture to the Mesoamerican societies that succeeded them is what historians are now exploring
- incorrect subject. This implies that the legacy is being overshadowed.
(D) the more ancient Olmec culture is now being explored by historians for its legacy to succeeding Mesoamerican societies
- correct! "overshadowed" is modifying "Olmec culture."
(E) the Olmec culture is more ancient and had a legacy to succeeding Mesoamerican societies that historians are now exploring
- "overshadowed" is correctly modifying "Olmec culture," but...
- "legacy to succeeding" is so unidiomatic that it's nonsensical.
- the central meaning should be that historians are exploring the culture BECAUSE of its legacy to other cultures. This incorrectly makes parallel "is ancient and had a legacy" and puts the historians in a modifying clause.
D has clearer meaning and idiomatic usage, so that's the correct answer.
