Hi,

what strikes you as unparallel in the original sentence?

We have:

Quote:
Sunspots... are visible as [X] but have never been sighted on [Y].

which is a perfectly acceptable construction.

It's not like there's a list or a common construction. Why do you think the sentence is bad? Why do you think there's a parallelism issue at all? Sentences only require parallelism when they have components that can be matched up. _________________ Stuart Kovinsky stuart.kovinsky@kaplan.com Kaplan Test Prep & Admissions Toronto Office 1-800-KAP-TEST http://www.kaptest.com/GMAT Prepare with Kaplan and save$150 on a course!

(A) are visible as dark spots on the surface of the
Sun but have never been sighted on : Hold
(B) are visible as dark spots that never have been
sighted on the surface of the Sun : Eliminated
(C) appear on the surface of the Sun as dark spots
although never sighted at : Hold
(D) appear as dark spots on the surface of the Sun,
although never having been sighted at Eliminated
(E) appear as dark spots on the Sun’s surface,
which have never been sighted on : Eliminated

Between A and C -

Sighted on is better. Moreover, the first clause in C introduces Sun Spots passively i.e appear as dark spots on Sun rather than actively are visible as dark spots on ...Sun.This is not a good way.

Hence C eliminated.

A prevails.

Picked A, just sounded the best.

Would this be more of an idiomatic issue?

Can anyone explain how does parallelism come into picture?
A has 'but' but other choices don't. Why do they need parallelism?
In fact, how does even A achieve parallelism?

I picked A, because of following ||ism.

Sunspots, vortices of gas associated with strong electromagnetic activity, are visible as dark spots on the surface of the Sun but have never been sighted on the Sun’s poles or equator.
