A means they were sipping coffee throughout the night. That is not intended at all :-)

So I will go with phrase "as they sipped". Next morning she realized something different about her husband. That happens very often ;-) ha ha

Try looking at it crudely:

(E) he seemed disoriented, she noticed, sipping their coffee the next morning.

Now, try taking out the unimportant matter. Generally, we find that content enclosed by commas are of lesser importance to the structure of a sentence.

Deploying that logic: he seemed disoriented sipping their coffee the next morning.

What does this now represent? That he got disoriented while sipping coffee in the morning!!

What should it mean, logically? That his wife noticed his disorientation while sipping coffee in the morning. The sipping of coffee is thus a background activity while her noticing his disorientation is the the main import of the sentence.

What supports this the BEST? Option C.

The use of the plural pronoun their makes it essential that we use a plural noun as well namely they. Just referring to only- she-, the subject - pronoun number distorts agreement. So A, B and E are dropped. Chocie D is somewhat odd with the use of several split phrases. The wrong word order of the phrase - she noticed- just prior to disoriented is suspect. Therefore, C would be ideal

Hi @bradfris,

When two independent clauses are not connected properly to each other, they are called run-on sentence. The most common instance is two ICs connected just by a comma. For example:

I can’t come to your house now, I am doing my homework.

Both the sentences here are independent clauses. They can stand by their own. We can very well use a full stop instead of the comma in this sentence. Joining these two sentences with comma leads to a run-on structure.

Hope this helps.
Thanks.

OA is C.

Clark and Florence Wallace, a husband-and-wife medical team, worked steadily and efficiently through the night, but sipping their coffee the next morning, she noticed that he seemed disoriented.

Note that there is a [,but] in the sentence, and to save efforts, let's analyze only the sentence after "but".

(A) sipping their coffee the next morning, she noticed that he seemed disoriented
Wrong.
The subject is "she", however is it irrational for the wife to drink up all "their" coffee alone.
Based on the context, we know that the wife actually did, too.

(B) sipping their coffee the next morning, he seemed to be disoriented, she noticed
Wrong.
Similar to A. It is irrational for the husband to drink up all "their" coffee alone.
The word "husband" is closer to "sipping", therefore grammatically only the husband drank the coffee.
But based on the context we know that the wife actually did, too.

(C) as they sipped their coffee the next morning, she noticed that he seemed disoriented
Correct.
Both the husband and wife are drinking coffee, and the wife noticed that her husband is disoriented.
(I have to admit that the simple past tense "sipped" makes me feel uncomfortable.)

(D) as they were sipping their coffee the next morning, he seemed, she noticed, disoriented
If there is no option A, I will go for D because the present progressive tense is perfect.
But here is my reason to cross out D:
In C,"she" is the subject, which means that the sentence is stressing the wife's discovery.
In D, "she noticed" is only a parentheses. And if you actually did so, the sentence is therefore stressing the husband's disorientation, not the wife's discovery.

(E) he seemed disoriented, she noticed, sipping their coffee the next morning
Wrong.
Same as A.

Hey Nightmare007 ,

Yes, it is perfectly fine to have two IC within a sentence provided they follow the rule perfectly.

Here is a great article that should help you. https://gmatclub.com/forum/unmasking-in ... 60401.html

I hope that helps. :-)

The action "sipping their coffee" cannot be done by just one person (i.e. she or he). It should be done by both people. All choices but the correct answer make this mistake.

(A) sipping their coffee the next morning, she noticed that he seemed disoriented - Wrong: 1) Modifier issue

(B) sipping their coffee the next morning, he seemed to be disoriented, she noticed - Wrong: 1) Modifier issue 2) 2 Independent clauses connected without a conjunction.

(C) as they sipped their coffee the next morning, she noticed that he seemed disoriented - Correct

(D) as they were sipping their coffee the next morning, he seemed, she noticed, disoriented - Wrong: 1) Modifier issue 2) 2 Independent clauses connected without a conjunction.

(E) he seemed disoriented, she noticed, sipping their coffee the next morning - Wrong: 1) Modifier issue 2) 2 Independent clauses connected without a conjunction.
