Hi Amit,
Great suggestions by everyone else thus far, and I have one more that you may find useful. If you think about it, when you narrow the answers down to 2 on any verbal question, by that point 4 out of the last 5 sentences that you've read will have been incorrect answer choices - just bad information.
Much like sushi restaurants give you the ginger slices and wineries give you soda crackers, in both cases to cleanse your palate of aftertaste so that you can appreciate what's next, you may need to cleanse yourself of the "aftertaste" of all of those incorrect answers. If you reread the question and the remaining two answer choices, treating it as a new question, you'll focus on the important components of your decision, and not be swayed or fatigued by the misinformation that you've read most recently.
In addition, you'll also find that, typically, GMAT verbal answer choices are usually incorrect for multiple reasons. 2-3 answer choices may, for example, be "out of scope" of the conclusion of an argument, but the last remaining answer choice will likely be wrong for a different reason. If you refresh the question and the remaining two answer choices before you make that final decision, you'll be more apt to recognize that a new thought process is required, and that the process you used to eliminate the initial answer choices won't work on the last one. Often times, students will narrow down to two and pick the one that "feels right" based on that current mindframe, but usually a second process is required.
