I know that " rock samples" is the subject of the sentence. I need some perfection in eliminating middlemen to find the subject and verb of a sentence. " the size" is between "about twice" and "of the 6-mile asteroid". how should I eliminate " the size".
The method i followed is "about twice the size of the 6-mile-wide asteroid " is a prepositional phrase. Is this correct.
The correct answer is E not C. "dated at" is the correct idiom
let me try:
Rock samples taken from the remains of an asteroid
about twice the size of the 6-mile-wide asteroid that
eradicated the dinosaurs has
been dated to be
billion years old and thus is
evidence of the earliest
known asteroid impact on Earth
been dated to be 3.47 billion years old and
been dated at 3.47 billion years old and thus
(C) have been dated to be
3.47 billion years old and
(D) have been dated as
being 3.47 billion years old
(E) have been dated at 3.47 billion years old and
Read the sentence removing the yellowed part. those are craps.
all part in red are wrong with respect to idioms and subject verb agreement.
E is correct.
hope this helps..!!
