IMO A is the right answer because it conveys the correct meaning as it states that Galileo published his theory and this activity was an attack and an exposition.


Galileo Galilei published his theory of the movement of planets in "Dialogue Concerning the Two Chief World Systems," an attack on the Ptolemaic conception of the Sun's motion as well as an exposition of his new theory to replace it.

A. an attack on the Ptolemaic conception of the Sun's motion as well as an exposition of his
this sentence is describing "Dialogue concerning the two chief world system" ... parallelism is good on this - an attack on...as well as an exposition of

B. an attack on the Ptolemaic conception of the Sun's motion and his expositing of a
this is not parallel .. attack on ....and his expositing

C. an attack on the Ptolemaic conception of the Sun's motion and expositing as well
this is not parallel .. attack on ....and expositing as well

D. attacking the Ptolemaic conception of the Sun's motion and also an exposition of his
Published his theory ...by attacking the conception ? modifier is not correct

E. attacking the Ptolemaic conception of the Sun's motion as well as the expositing of his
Published his theory ...by attacking the conception ? modifier is not correct

A seems to be the better answer!

I say its A! A.

"an attack on the Ptolemaic conception of the Sun's motion"

"as well as" acts as the conjunction - and

an exposition of his

I think it might be E. I am not far into SC yet and would appreciate an explanation if possible. I can't feel like it's "an."

A little bit analysis of the options suggest that the difference in options is of parallelism between 2 events: 'attack' and 'exposition'. Only options that follow correct parallelism is option A and option E.

The difference between A and E is of verb tense. Looking at first half of the question: 'published' suggest simple past tense, and not continuous tense; thus option A

Competition Mode Question



Galileo Galilei published his theory of the movement of planets in "Dialogue Concerning the Two Chief World Systems," an attack on the Ptolemaic conception of the Sun's motion as well as an exposition of his new theory to replace it.

A. an attack on the Ptolemaic conception of the Sun's motion as well as an exposition of his

B. an attack on the Ptolemaic conception of the Sun's motion and his expositing of a

C. an attack on the Ptolemaic conception of the Sun's motion and expositing as well

D. attacking the Ptolemaic conception of the Sun's motion and also an exposition of his

E. attacking the Ptolemaic conception of the Sun's motion as well as the expositing of his

Official Explanation



Creating a filter: The prompt starts out well but runs into problems with "as well as," a phrase that is rarely well used. We check out the answer choices looking for better options.

Applying the filter: we find bigger defects; there are parallelism problems with the attacking and the expositing all over the place here. Choices (B) through (E) all fail to be parallel. Choice (E) looks close but the article "the" before "expositing" makes it a noun and ruins it. The correct answer is (A). We could defend the "as well as" the way it's written as needed to remove ambiguity and clarify that the Dialogue wasn't an attack on the exposition, but it doesn't matter, as long as we find objective grounds for our answer.

The correct answer is (A).
