Official Explanation
In many countries, sparkling wine can only be called Champagne if the wine is produced following specific guidelines and using certain grape varieties, from the white Chardonnay, Pinot Noir, and Pinot Meunier usually, or occasionally including—as a result of the 2010 version of the appellation regulation—from the Arbane, Petit Meslier, Pinot Blanc, and Pinot Gris.
A. from the white Chardonnay, Pinot Noir, and Pinot Meunier usually, or occasionally including
B. from the white Chardonnay, Pinot Noir, and Pinot Meunier usually, or occasionally it includes
C. and includes usually from the white Chardonnay, Pinot Noir, and Pinot Meunier or occasionally
D. usually from the white Chardonnay, Pinot Noir, and Pinot Meunier and occasionally it includes
E. usually from the white Chardonnay, Pinot Noir, and Pinot Meunier and occasionally
After a quick glance over the options, we have a couple major differences we can focus on:
1. from…usually / and includes usually from / usually from (Parallel Structure)
2. or occasionally / and occasionally (Meaning)
3. including / it includes (Pronouns & Meaning)
Let’s start with #2 on our list because it’s an either/or split. No matter which direction we go in, we’ll eliminate 2-3 options rather quickly. In this case, it’s a matter of meaning.
Are we trying to say that only one list or the other is allowed to be called Champagne? Or are we trying to say that both lists are allowed to be called Champagne? According to the original sentence, BOTH lists of grapes are now allowed to be used to make Champagne. Therefore, we need to use “and” to show that both lists apply, and eliminate any that use “or.”
A. from the white Chardonnay, Pinot Noir, and Pinot Meunier usually, or occasionally including
B. from the white Chardonnay, Pinot Noir, and Pinot Meunier usually, or occasionally it includes
C. and includes usually from the white Chardonnay, Pinot Noir, and Pinot Meunier or occasionally
D. usually from the white Chardonnay, Pinot Noir, and Pinot Meunier and occasionally it includes
E. usually from the white Chardonnay, Pinot Noir, and Pinot Meunier and occasionally
We can eliminate options A, B, & C because using “or” changes the intended meaning of the sentence. Now that we have it narrowed down to only 2 options, let’s focus on #1 and #3 on our list to determine which is the better choice. To make problems easier to spot, we’re going to add in the rest of the list (minus the non-essential phrase). Let’s see how each option shakes out:
D. usually from the white Chardonnay, Pinot Noir, and Pinot Meunier and occasionally it includes from the Arbane, Petit Meslier, Pinot Blanc, and Pinot Gris.
This is INCORRECT because the two lists aren’t introduced using parallel wording. Also, the pronoun “it” isn’t 100% clear here – what is “it” referring back to?
E. usually from the white Chardonnay, Pinot Noir, and Pinot Meunier and occasionally from the Arbane, Petit Meslier, Pinot Blanc, and Pinot Gris.
Here is the CORRECT choice! Both lists are introduced using a similar format (adverb + from + the), and there aren’t any unclear pronouns in sight!
There you have it – option E is our winner! By removing the non-essential clause, we were able to figure out what areas to focus on without being confused by such a long-winded and complex sentence!
