Can 'have' and 'are' be parallel? They are brilliant but have never practiced the sport. Seems funny.

Dear OreoShake,

I'm happy to respond.

My friend, remember that parallelism is primarily a logical structure, and the grammar is secondary to the logic. Remember that we always can create parallel structures that are grammatically flawless and logically absurd.
I cooked dinner with fresh carrots, with enthusiasm, and with my friend Chris.

The short answer to your question is "yes"---of course "are" and "have" can be parallel. In fact, "is/are" can be parallel with any other verb. The caveat, as with all parallelism, is that the parallelism must be logically sound.

Does all this make sense?

This is indeed not a test of //ism; rather it is about meaning and grammar. If you are thinking about the verb //ism here, there is only one // marker, namely, the fanboy conjunction but. The verbs on either sides of the ‘but’ are in present and present perfect tenses, which is acceptable.

(A) are visible as dark spots on the surface of the Sun but have never been sighted on ---- correct choice.
(B) are visible as dark spots that never have been sighted on the surface of the Sun ----- the vortices have been sighted on the surface; Choice says they never have been sighted; total reversal of the original meaning
(C) appear on the surface of the Sun as dark spots although never sighted at ---- although never have been is a fragment; The subordinate conjunction’ although’ requires a subject and verb or minimum a verb’
(D) appear as dark spots on the surface of the Sun, although never having been sighted at – ‘although never having been sighted at’ is not a sub-clause; same problem as in C
(E) appear as dark spots on the Sun's surface, which have never been sighted on – which flouts the relative pronoun touch rule

A is the choice

Sir,

Here are some findings on although(Courtesy to the great Ron..)

1. If it is placed in the beginning of the sentence, then ‘although’ can be followed by either a clause or a modifier.

Example: Although still continuing elsewhere, polio has been eradicated in the United States and could be brought into the country by visitors.
Although eradicated in the United States, polio continues elsewhere and could be

2. If 'although' is placed in the middle of a sentence, then it can only be a modifier and never a clause
Example: Polio, although eradicated in the United States, it still continues elsewhere and can be

3. If the ‘although’ is placed in the end portion, then it can only be a clause and never a modifier.
Ex: (imaginary); polio continues elsewhere and could be brought into the country by visitors, although it was eradicated in the United States

For option C in the following question,It is rule no #3

Hi ydmuley ,

We have

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.

Quote:
(A) are visible as dark spots on the surface of the Sun but have never been sighted on

Okay, this sentence implies the sun spots were not seen in the past and not even now. But still they are visible as dark spots. Hence, Correct answer.

Quote:
(B) are visible as dark spots that never have been sighted on the surface of the Sun

This choice is run on. Try to connect this choice with the original sentence. You will find the error as highlighted below:

Sunspots are visible as dark spots that never have been sighted on the surface of the Sun the Sun’s poles or equator.

Did you notice what I am saying? Sun the Sun's poles?? What is this? Hence, Incorrect.

Quote:
(C) appear on the surface of the Sun as dark spots although never sighted at

Okay, here is the catch. It says never sighted at. So, this happened in the past. Does that mean they are sighted now? We don't know, right?

Now, you could ask me which is the correct idiom "sighted at" or "sighted on". My answer will be I don't care about idioms unless I don't have any other option than to care about it. Technically, I believe sighted on means I have an object on which I am having something while sighted at means at some place? Again, I don't care about it.

Hence, it is not giving the intended meaning. Hence, out.

Quote:
(D) appear as dark spots on the surface of the Sun, although never having been sighted at

The usage of having been is incorrect here. Although should have a clause with it. But when I am saying 'never having been..', I am missing the correct usage.

Quote:
(E) appear as dark spots on the Sun's surface, which have never been sighted on

It implies Surface of the sun have been sighted on the pole. Lol. This cannot happen. Hence, Incorrect.

Does that make sense?

Thanks abhimahna for the detailed post!

Along with the points that you mentioned, the usage of "although" also has a major role to play.

"Although" normally introduces a subordinate clause, just as "while" does. This means we will need a subject and a verb in the sentence containing "Although".

So, for answer choice C, which I selected, we are missing a clear subject and as you mentioned the verb "sighted" in this case, the verb "Sighted" is considered incomplete as it should also have supporting verb to make clear sense out of it.

Thanks again!

Yes, that's true. We can also reject C for the reason we rejected D.

I didn't look at it because I had another solid reason to reject C.

But your reasoning is also correct.
