These types of questions contain grammatical errors in the underlined sentence and we have to choose the correct statement from the options. GMAT sentence correction is a part of GMAT verbal.

Answer: E
Explanation: The given sentence correction question can be checked by the given-below rules:

• Parallelism
• Comparison of two elements
• Modifiers

Option A: Incorrect

Option A is incorrect. The use of the word “knowledgeable” is not in accordance with the sentence following after. There has been a use of the word “in attendance” which makes the sentence more redundant.

Option B: Incorrect

Option B is incorrect. There has been a use of the word “in attendance” which makes the sentence more redundant. The use of the word “did not know” is not correct as the previous word is “attendance” which is not the main object.

Option C: Incorrect

Option C is incorrect. The use of the word “for” is redundant as the use of the word “ because” would fit well in the sentence. It is eliminated due to the use of the word “with”. These words change the meaning of the sentence from “not everyone knew” to “everyone did not know”. Both of these are different sentences having different meanings.

Option D: Incorrect

This option is incorrect. It is eliminated due to the use of the word “with”. These words change the meaning of the sentence from “not everyone knew” to “everyone did not know”. Both of these are different sentences having different meanings.

Option E: Correct

Option E is correct. The word “knew” is perfectly written to maintain the meaning of the sentence coming after. It is the best choice among all the options.
