Answer: 1. A. God
2. A. Infuriated
Let's talk about the first question. From the excerpt, we may understand that Adam, after having a revelation, after understanding "how it works", concludes that, if he knows he it works, he "must have invented it". That seems to mean that, once man became rational and capable of logical thinking, he started to question God's existence - if God cannot be explained, he does not exist. Thus, the best answer seems to be letter A.
Let's move on to the second question. Right from the beginning of the excerpt, we may understand that Mr. Chiu is mad at his wife to the point of thinking "What a stupid woman!" Since she didn't do what he expected the way he expected it to be done, he thinks of her as useless. The adjective "patronizing" describes someone who acts with a superior attitude toward others, in a condescending manner, and that's why I do not believe it to be the best option. His words would be a mix of pity, contempt, and politeness. From the exclamation "What a stupid woman!", we can tell he's simply infuriated. So, I believe the best option to be letter A.
