Official Solution:

The adoption of either method of extraction, open-pit mining or solution mining, will require miners to be certified in the use of safety equipment.

A. open-pit mining or solution mining
B. open-pit mining and solution mining
C. open-pit and solution minings
D. open-pit mining, including solution mining
E. mining by open-pit or by solution

This sentence requires the grammatically correct extension of the phrase either method of extraction. The underlined portion must show contrast and agree with the singular word either by using the conjunction or.
  1. This option correctly extends the phrase in the first part of the sentence to read either…open-pit mining or solution mining.
  2. And is an incorrect conjunction, because it does not agree with either.
  3. This option may seem more concise, but and is incorrect because it does not agree with either, and minings should not be plural.
  4. In this option, the meaning of the sentence has been changed to incorrectly suggest that solution mining is a kind of open-pit mining.
  5. Mining is redundant in this context, because it repeats the words method of extraction. This word order also makes the sentence awkward and confusing.

Answer: A

There may be difference opinion among grammarians whether "either..or" structure can be used for more than two options. However in GMAT such dubious points are not generally tested. (Neither it is tested in this question.)

It looks like "Open Pit mining or Solution mining" is used as an non essential modifier here. With or without the underlined portion the sentence still makes sense? If true, Open Pit mining AND Solution mining makes sense here. Isnt it?
