"lack of objection" is the attributive of "accusation".
The structure of the first half of this sentence is:
This discovery makes the judge face charges ...
Translation:
Although some people accuse one of the defense lawyers of being a friend of the judge, which may make the judge lack impartiality in judging the case, the judge insists that knowing does not mean favoritism.
(The contestants are translated as "defense lawyers"; Unfortunately, his destructive attack on the consequences of economic policy was weakened by his wholehearted acceptance of the basic assumptions of the policy.
unfortunately, because he fully accepted the most basic assumption of this economic policy, his powerful attack on some aspects of economic policy gradually softened.
This sentence is really not easy to translate. It's rather embarrassing. Let it go, GRE. Ha ha. . )
3. Ironically, the author of this book is as sensitive and knowledgeable as an Indian craftsman, and she didn't cultivate her interest in Native American art until she was an adult, because she grew up in an area rich in American Indian culture.
(The author is not interested in native American art because he lived in the environment of American Indian culture when he was a child. This thing is ironic. How to understand it? )
The writer is Indian. She grew up in a very rich environment of American Indian culture, but she was not interested in American culture until she became an adult.
That is to say, this person has been exposed to American culture since childhood. According to common sense, she should have been interested in American native culture long ago, but it was not until 26 that she began to pay attention to and become interested in American culture. So it's a little ironic.
I wish you success in the GRE exam. Taking the G test is really painful. Stick to it step by step. Believe in yourself, and you will get good grades in the exam. )
