When would you use had not/ did not?
EG. Katherine felt that she had not had/ did not have any understanding of the highly intricate workings of the stock market until her uncle took her to the New York STock Exchange.
What is the difference in using while, when, as? They are all prepositions of time, right? |

The past perfect tense "had not had" is the correct answer. The past perfect tense is used to say something happened before another thing in the past (her uncle took her to the New York Stock Exchange).

"While", "when", and "as" are all used for saying that something happens at the same time as something else. They are subordinating conjunctions, used to introduce an adverb clause of time.
Hope this helps.
