Hi All,

Please read this before posting your reply.

Source of this question is OG-12. This question might have been discussed in BTG already. The very reason I am posting again is to approach SC in a structured way. Hence, I request everyone to post their comments in the following manner.

IMO: A/B/C/D/E

Approach/Steps used for choosing the right answer.

For other options, List the errors associated in the following style:
Option: A/B/C/D/E
Subject-Verb Agreement : NA
Parallelism: NA
Pronouns: NA
Modifiers: NA
Verb Tense:NA
Voice and Mood:NA
Comparisons:NA
Idioms:NA
Meaning/Conciseness:NA
Others:NA

This definitely takes a bit more time and effort. But it will help a lot of students to master OG questions/strategies. We need to know the best approach to solve these. It is equally important to know why the wrong answers are wrong. Explanation for each option will detail that out. Plan is to compile all these threads to a single place for future reference. Hope everyone agrees with me!!
