Example Input: Question: What's the difference between these two phrases? 
Answer: To add to Martha's answer: The simple past ("Did you see this") refers about an event in the past The present perfect ("Have you seen this") suggests a link with the present time. If "this" is something you could have seen but cannot anymore (you should have been there seeing "this" at the time, but it wouldn't have the same impact if you see it again now), then "Did you see" is more appropriate. It is about an event that happened once in the past. If "this" is something you can check out whenever you want, "Have you seen" is more to the point, because it suggests that, if you haven't seen it in the past, you could consider seeing it now or in the near future. It is about an event which can happen again or is still relevant in the present.
Example Output: yes

Example Input: 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.
Example Output:
yes
