Sentence Correction: Parts of Speech - Adjective

The Passage Tomb at Newgrange, considered one of the world's most outstanding remains of the Megalithic period, an underground burial chamber that lies under a kidney-shaped mound surrounded by 97 decorated kerbstones, attracts some 200,000 visitors every year.

Incorrect.

[[snippet]]

This answer choice is illogical. The modifier an underground burial chamber[...] is incorrectly placed after the modifier considered one of the world's [...], and therefore seems to modify the noun the Megalithic period rather than the Passage Tome at Newgrange. However, the Megalithic period is not an underground chamber.

The Passage Tomb at Newgrange, <-- considered one of ... the Megalithic period, <-- an underground burial chamber ...

As you can see, placing the modifiers one after the other creates a reference problem.

Incorrect.

[[snippet]]

This answer choice repeats the original logical mistake. The modifier considered one of the world's [...] is incorrectly placed after the modifier an underground burial chamber[...] and therefore seems to modify the noun kerbstones rather than the Passage Tome at Newgrange. However, the kerbstones are not one of the world's most outstanding remains - the passage tomb is.

The Passage Tomb at Newgrange, <-- an underground burial chamber ... kerbstones <-- considered one of ... 

As you can see, placing the modifiers one after the other creates a reference problem.

Incorrect.

[[snippet]]

This answer choice is grammatically incorrect. The Dangling Modifier considered one of the world's [...] should be followed by the noun it modifies (the Passage Tomb at Newgrange) in the main clause. However, it is followed by another modifier: an underground burial chamber[...].

Even though this reference does not change the meaning, an underground burial chamber [...] is a modifier and not a noun subject of a clause as it is not followed by a conjugated verb.

Considered one of ... , --> an underground burial chamber ... [?] , the Passage Tomb at Newgrange

As you can see, placing the modifiers one after the other creates a reference problem.

Incorrect.

While this answer choice corrects the original logical mistake, it is grammatically incorrect and stylistically flawed: 

  • the phrase considered as being is wordy and redundant
  • the phrase lies underground a .. mound is grammatically incorrect as underground is an adjective and not a preposition.

Well done!

[[snippet]]

This answer choice corrects the original logical mistake by placing one modifier (Considered one of the world's ...) directly before the noun (the Passage Tomb at Newgrange) and the other modifier (an underground burial chamber..) directly after the same noun.
