[Q]: Question: I sometimes see the term "critical but stable" in the news. It is often used to describe someone who has been very seriously injured. For example (15 December 2019): "[A police officer] said the man who had been shot was in a "critical but stable " condition in hospital." I understand that "critically ill" means that life is in danger. Similarly "stable" is the opposite. Quotes from www.lexico.com critically To an extreme degree with a risk of death. 'two critically wounded people died in hospital'. 'critically ill patients who were awaiting surgery' stable (of a patient or their medical condition) not deteriorating in health after an injury or operation. 'he is now in a stable condition in hospital' What does "critical but stable" really mean? 
Answer: It seems contradictory on the surface, but it really does just combine the definitions you listed. So,the patient's condition is very serious or an extreme degree of injury, but not currently deteriorating or worsening.
[A]: yes


[Q]: Question: Most grammar checkers are capable of detecting the the misuse of "your" and "you're"; providing the necessary correction. I'm curious though, is there any sentence that can be constructed where replacing "your" with "you're" keeps the sentence grammatically correct, but changes the meaning? If this is not possible, what grammar rules are in place that prevents these edge cases from occurring? 
Answer: a. I love you and your bananas. b. I love you and you're bananas. This particular case depends on the your/you're coming after an independent clause followed by "and," since its feasibility depends on functioning either as a second direct object or as another independent clause. It also depends on the noun serving either as a thing that someone might be in possession of (the bananas we eat) or as an adjective or noun complement describing a person (bananas=crazy). Easiest if that noun is plural or uncountable. The same sentence could be constructed with nuts, garbage, and other nouns which I'll let you brainstorm because my stormer hurts. You can also (and thanks to @Barmar for drawing attention to this) use verbs, in which case they act as a gerund with the possessive pronoun and a present participle with the "you're." As in: a. I love you and your cooking. b. I love you and you're cooking. Or: a. I despise you and your smoking. b. I despise you and you're smoking.
[A]: yes


[Q]: Question: Sometimes people are referring to mechanical objects as "she": I love my car. She always gets the best service. Are there any rules when it is appropriate to use "she" instead of it, and is "he" ever used in such context? 
Answer: The reason why cars and alike are called "She" is because ships are made from Female oak, being that the wood is much stronger than the male oak... This I was told by a ship builder many years ago... Basically anything Mechanical is now referred to as "She".
[A]:
no
