Vocabulary questions

Hello everyone,  

I was doing a vocabulary test and I couldn't solve a few questions. Unfortunately, I don't have the key. I hope you will help me.  

Thanks in advance.    

Here are the questions: 1- Not only did she ..... from Christianity to Islam but she also changed her name before marriage. A) go through B) go with C) go to D) go over E) go for.  I looked up the meanings from dictionary but I really couldn't find something meaningful but ı guess it may be go through because the other prepositios doesn't sound good to my ears before from.  

2-Viewers often find the paintings of the photo-Realist school somewhat disconcerting. In this sentence they want us to fins the synonym of the underlined word.  A) rather B) thoroughly C) very D) instrinsically I think it should be A because the other ones sound funny in the context.(At least to me)  

3-No other newspaper columnist has managed as yet to rival Ann Lander's popularity in terms of readership. This is a find the synonym question too. A) though B) in spite of this C) even D)so far I think it should be so far but I don't understand the usage of as yet here. Is it a kind of reduction?   

4- A group of soldiers refused to..... the new government, thus leading to discord in the country. A) admit B)accept C) surrender D) recognise E) vizity I guess it should be either accept or admit but the two words confuse me. I looked up their meanings and both of the verbs are used to explain the other one in the dictionary. However, accept says choose me to me.

Thank you for your answer Philip but I really didn't understand what as yet stand for and why accept is correct but not admit?

I think that #4 is "D) recognize"

This is the first time I've tried tinyURL so here's the whole thing in the even that it didn't work:

Just use my excuse -- It was the British usage(nise and not nize). LOL
